## What is Bitcoin? 
Bitcoin is a unit of currency that is used for store & transmit value among participants in the bitcoin network.\
Users can transfer the bitcoin over the network to do just anything that can be done with conventional currencies , such as buy & sell goods , send money to people or organisations,or extend credit.Unlike traditional currencies bitcoins are entirely invisible.
## History of Bitcoin
Bitcoin was invented in 2008 by Satoshi Nakamoto with the publication paper titled "Bitcoin: A peer-to-peer Electronic Cash System".\
The bitcoin network started in  2009, based on a reference implementation published by Nakamoto & since revised by other programmers .\
The largest transaction processed so far by the network was $150 million US dollars , transmitted easily without any fees.

## What is Blockchain? 
- The term “blockchain as a centralized ledger” is somewhat of a misnomer because the defining characteristic of blockchain technology is its decentralized nature. However, it’s possible to have a blockchain-like structure that is centrally controlled, which could be referred to as a “centralized blockchain".
---
## Key Concepts of Blockchain technology

The key concepts of blockchain technology are:

### Blocks
In blockchain technology, a block is a fundamental component that stores a collection of transactions. Here’s a breakdown of what a block typically contains:

- **Block Header**: This includes metadata about the block, such as the version number, a reference to the previous block’s hash (linking it to the chain), the timestamp, and the difficulty target for mining.
- **Transaction Counter**: It indicates the number of transactions included in the block.
- **Transaction List**: This is the core of the block, containing all the transactions that have been validated and confirmed by the network since the last block was created.

### Transactions
In blockchain technology, transactions represent the actions carried out by participants within the network. Here’s a simplified overview of how transactions work:

- **Initiation**: A user initiates a transaction by creating and signing it with their private key. This ensures the authenticity of the transaction.
- **Broadcast**: The signed transaction is broadcast to the network and awaits validation by the nodes.
- **Validation**: Network nodes verify the transaction’s validity, including the digital signature and the sufficiency of funds.
- **Block Formation**: Once validated, the transaction is grouped with other pending transactions to form a new block.
- **Consensus**: The new block is then confirmed through a consensus mechanism, such as Proof of Work or Proof of Stake, depending on the blockchain protocol.
Chain Addition: After consensus is reached, the new block is added to the existing blockchain, creating a permanent and immutable record of the transaction.
- **Completion**: The recipient receives the transferred asset once the transaction is recorded on the blockchain.

### Nodes
In blockchain technology, nodes are the individual computers that make up the network. They play a crucial role in the functioning of the blockchain by performing several key tasks:

- **Validation**: Nodes validate new transactions and blocks, ensuring they adhere to the network’s rules.
- **Propagation**: Nodes spread transactions and blocks to other nodes, facilitating the peer-to-peer nature of the network.
- **Storage**: Full nodes store a complete copy of the blockchain ledger, maintaining the network’s transaction history.
- **Consensus**: Nodes participate in the consensus process, which is necessary to agree on the state of the ledger and confirm transactions.
- **Security**: By being distributed, nodes contribute to the security of the network, making it difficult to tamper with the transaction data.

### Cryptography
Cryptography is a fundamental aspect of blockchain technology, providing the necessary security and trust mechanisms. Here’s how it works in the context of blockchain:

1. **Encryption**: Cryptography allows for the encryption of data, ensuring that only authorized parties can access the information. In blockchain, this is crucial for maintaining the privacy of transactions.
2. **Digital Signatures**: It uses cryptographic algorithms to create unique digital signatures. These signatures verify the authenticity of a transaction and confirm that it has not been tampered with.
3. **Hash Functions**: A hash function takes input data and produces a fixed-size string of bytes. In blockchain, each block contains the hash of its transactions and the hash of the previous block, creating a secure link.
4. **Public and Private Keys**: Blockchain uses asymmetric cryptography, where each user has a pair of keys: a public key, which is shared with others, and a private key, which is kept secret. The public key is used to encrypt data, and the private key is used to decrypt it.
5. **Integrity and Security**: Cryptography ensures the integrity and security of the blockchain by making it computationally infeasible to alter transaction data once it has been included in a block.
6. **Consensus Mechanisms**: Cryptographic techniques are also used in various consensus mechanisms like Proof of Work or Proof of Stake to secure the network and validate transactions.
---
## How Blockchain Works
The step-by-step process of a transaction in blockchain technology typically involves the following stages:

1. **Transaction Creation**: A user initiates a transaction by creating a digital signature using their private key. This signature is used to authenticate the transaction.
2. **Broadcast to Network**: The transaction is then broadcast to the blockchain network, where it is visible to all nodes.
3. **Verification by Nodes**: The network of nodes verifies the transaction’s validity, ensuring that the digital signature matches the public key and that the transaction adheres to network rules.
4. **Transaction Pool**: Verified transactions are pooled together in the memory pool (mempool) while they await inclusion in a block.
5. **Block Creation**: Miners or validators select transactions from the mempool and form a new block. In Proof of Work (PoW) systems, miners solve complex mathematical puzzles to create a block. In Proof of Stake (PoS) systems, validators are chosen based on their stake in the network.
6. **Block Verification**: Once a block is created, it is verified by other nodes. If the block is valid, it will be accepted by the network.
7. **Adding to Blockchain**: The new block is then added to the existing blockchain. This addition is permanent, and the block cannot be altered without redoing the work of subsequent blocks.
8. **Transaction Completion**: After the block is added to the blockchain, the transaction is considered complete, and the recipient receives the transferred asset or information.

Blockchain is a decentralized , distributed ledger technology that records transection across multiple   computers in a way  that is secure, transparent & immutable It consists of series of blocks, each containing a cryptographic hash of previous block , creating a chain blocks.

Creating an accordion with HTML and CSS is a great way to add interactivity to your website without relying on JavaScript. An accordion allows you to present content in a compact and organized way, making it easier for users to navigate and find the information they need. In this tutorial, we’ll walk you through the steps to create a simple and elegant accordion using just HTML and CSS.

## Step 1: HTML Structure

First, let’s set up the HTML structure for our accordion. We will use a combination of `ul`, `li`, `input`, `label`, and `div` elements. The `input` elements will be of type `radio`, allowing us to control which accordion section is expanded.

Create a file named `index.html` and add the following code:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Accordion with HTML & CSS</title>
    <link rel="stylesheet" href="index.css">
</head>
<body>
    <ul class="accordion">
        <li>
            <input type="radio" name="accordion" id="first" checked>
            <label for="first">Products</label>
            <div class="content">
                Lorem ipsum dolor sit amet consectetur adipisicing elit. Ex, in. Ut alias temporibus, ea perferendis mollitia odio ratione provident. Delectus?
            </div>
        </li>
        <li>
            <input type="radio" name="accordion" id="second">
            <label for="second">Cart</label>
            <div class="content">
                Lorem ipsum dolor sit amet consectetur adipisicing elit. Ex, in. Ut alias temporibus, ea perferendis mollitia odio ratione provident. Delectus?
            </div>
        </li>
        <li>
            <input type="radio" name="accordion" id="third">
            <label for="third">Accounts</label>
            <div class="content">
                Lorem ipsum dolor sit amet consectetur adipisicing elit. Ex, in. Ut alias temporibus, ea perferendis mollitia odio ratione provident. Delectus?
            </div>
        </li>
        <li>
            <input type="radio" name="accordion" id="fourth">
            <label for="fourth">List</label>
            <div class="content">
                Lorem ipsum dolor sit amet consectetur adipisicing elit. Ex, in. Ut alias temporibus, ea perferendis mollitia odio ratione provident. Delectus?
            </div>
        </li>
    </ul>
</body>
</html>
```

In this structure, each accordion item is represented by an `li` element containing an `input` (radio button), a `label`, and a `div` with the class `content`.

## Step 2: CSS Styling

Next, we’ll style our accordion using CSS. Create a file named `index.css` and add the following code:

```css
@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@400;500;700&display=swap');

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

.accordion {
    color: white;
    font-family: 'Roboto', sans-serif;
    margin: 60px auto;
    width: 600px;
}

.accordion li {
    width: 100%;
    margin: 20px 0;
    padding: 10px;
    list-style: none;
    background-color: #0f172a;
    border-radius: 8px;
    box-shadow: 0 5px 5px rgba(0, 0, 0, 0.1);
}

.accordion li label {
    display: flex;
    align-items: center;
    font-size: 18px;
    padding: 10px;
    font-weight: 600;
    cursor: pointer;
}

label::before {
    content: "+";
    margin-right: 24px;
    font-size: 24px;
    font-weight: 700;
}

input[type="radio"] {
    display: none;
}

.accordion .content {
    color: #cbd5e1;
    padding: 0 10px;
    line-height: 26px;
    max-height: 0;
    overflow: hidden;
    transition: max-height 0.5s, padding 0.5s;
}

.accordion input[type="radio"]:checked + label + .content {
    max-height: 400px;
    padding: 10px;
}

.accordion input[type="radio"]:checked + label::before {
    content: "-";
}
```

In the CSS file, we’ve styled the accordion to have a sleek and modern look. Key points include:
- Importing the Roboto font for better typography.
- Styling the accordion items with a dark background, white text, and rounded corners.
- Hiding the radio inputs to make the accordion labels clickable.
- Using transitions to animate the opening and closing of the accordion content.

## Conclusion

With these simple steps, you’ve created a functional and stylish accordion using only HTML and CSS. This technique leverages the power of CSS transitions and radio buttons to create an interactive UI component without any JavaScript. Feel free to customize the styles and content to better fit your project’s needs. 

Now you have a clean, accessible, and easily maintainable accordion for your web pages. Happy coding!

Creating an accordion with HTML and CSS is a great way to add interactivity to your website without relying on JavaScript. An accordion allows you to present content in a compact and organized way, making it easier for users to navigate and find the information they need.

How to create Accordion with HTML & CSS

In the realm of web development, adding animations can bring life and interactivity to a webpage, enhancing user experience and engagement. Scalable Vector Graphics (SVG) offer a versatile and lightweight option for creating animations that scale seamlessly across different screen sizes and resolutions. With CSS (Cascading Style Sheets), you can manipulate SVG elements to create captivating animations without relying on JavaScript or external libraries. Let's delve into the fascinating world of SVG animations powered solely by CSS.

## Understanding SVG

SVG is an XML-based format for vector graphics, allowing you to define shapes, paths, text, and more. Unlike raster images, SVG graphics maintain their quality regardless of the display size, making them ideal for responsive web design. SVG elements can be styled and animated using CSS, providing endless possibilities for creative expression.

## Getting Started

To begin, you'll need a basic understanding of HTML and CSS. Start by creating an HTML file and embedding an SVG element within it. You can either include an inline SVG or reference an external SVG file using the `<img>` tag. For simplicity, let's use an inline SVG:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>SVG Animations with CSS</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <svg width="100" height="100">
        <circle cx="50" cy="50" r="40" fill="blue" />
    </svg>
</body>
</html>
```

## Adding CSS Animation

Now, let's animate the SVG circle using CSS. Create a separate CSS file (styles.css) and define the animation:

```css
@keyframes spin {
    0% { transform: rotate(0deg); }
    100% { transform: rotate(360deg); }
}

circle {
    animation: spin 2s linear infinite;
}
```

In this example, we've defined a keyframe animation called "spin" that rotates the circle 360 degrees clockwise continuously over a duration of 2 seconds. Then, we apply this animation to the SVG circle using the `animation` property.

## Exploring Animation Properties

CSS provides a plethora of animation properties to control the timing, duration, and behavior of animations. You can experiment with properties like `animation-duration`, `animation-timing-function`, `animation-delay`, and `animation-iteration-count` to achieve the desired effect. Additionally, CSS transforms and transitions can be applied to manipulate SVG elements further.

## Advanced Techniques

Beyond basic animations, CSS offers advanced techniques for creating complex SVG animations. You can animate individual SVG elements, apply gradients, morph shapes, and synchronize multiple animations for stunning visual effects. By combining CSS animations with media queries, you can create responsive animations that adapt to different screen sizes and orientations.

## Conclusion

In conclusion, SVG animations powered by CSS provide a lightweight and efficient way to add dynamic content to your web projects. By leveraging the expressive power of SVG and the flexibility

In the realm of web development, adding animations can bring life and interactivity to a webpage, enhancing user experience and engagement. Scalable Vector Graphics (SVG) offer a versatile and lightweight option for creating animations that scale seamlessly across different screen sizes and resolutions. With CSS (Cascading Style Sheets), you can manipulate SVG elements to create captivating animations without relying on JavaScript or external libraries.

## Introduction 
If you are preparing for interview & you are finding the top html interview questions, then this post is for you.
In this blog post , first we will see what is html & why it is used . Then we will see top interview questions related to html & thier answers with proper explanation. If you want to crack interview then read the complete blog post. 
## What is html?
Before going forward we will see , what is html? Html is a *hypertext markup language*. It is a standard markup language used to create web pages. 
It defines structure & layout of web pages by using variety of tags.

## Top interview questions:
1. What is html? \
**Ans**: HTML stands for HyperText Markup Language. It is the standard text formatting language used for creating and displaying web pages on the Internet. HTML documents consist of elements and tags that format content for proper display.

2. What are html tags? \
**Ans**: HTML tags are used to place elements in the appropriate format. Tags are enclosed in angle brackets (< and >). Some tags require closing tags (e.g., <p>), while others are self-closing (e.g., <img>).

3. What are html attributes?\
**Ans**: *Attributes* are properties added to HTML tags. They modify how a tag behaves or is displayed. For example, the <img> tag has an src attribute to specify the image source.
4. What is marquee tag in html?\
**Ans**: A *marquee* is used for scrolling text or images on a web page. It automatically scrolls content up, down, left, or right. To create a marquee, use the <marquee> tags.

5) How do you separate sections of text in HTML?\
**Ans** :
- <br> tag: Separates lines of text by breaking the current line and shifting the flow to a new line.
- <p> tag: Defines a paragraph of text.
- <blockquote> tag: Used for large quoted sections.

6. Define the list types in HTML.\
**Ans**:
- Ordered list: Uses the <ol> tag and displays elements in a numbered format.
- Unordered list: Uses the <ul> tag and displays elements in a bulleted format.
7. How do you align list elements in an HTML file?\
**Ans**: 
To align list elements in an HTML file, you can use CSS (Cascading Style Sheets) to apply alignment properties to the list items. Here are a few common methods:

- **Text Alignment:** You can align the text within list items using the `text-align` property. For example, to align the text to the left, right, or center within a list, you can use:

```css
ul {
    text-align: left; /* or right, center */
}
```

- **List Item Alignment:** You can also align the list items themselves using the `list-style-position` property. This property determines whether the list item marker appears inside or outside the content flow. For example, to align the list items to the center:

```css
ul {
    list-style-position: inside; /* or outside */
}
```

- **Using Flexbox or Grid:** If you need more control over the layout, you can use CSS Flexbox or Grid layout techniques. These provide powerful tools for aligning and positioning elements within a container. For example, using Flexbox to align list items horizontally:

```css
ul {
    display: flex;
    justify-content: center; /* or other values like flex-start, flex-end */
}
```
8. Differentiate between an Ordered list and an Unordered list? \

9. what is an element in html? \
**Ans**: In HTML, an element is a fundamental building block that defines the structure and content of a web page. An HTML element consists of several parts:

- **Start Tag**: The opening tag that marks the beginning of the element. It is enclosed in angle brackets (`< >`) and usually contains the name of the element.
   
- **End Tag**: The closing tag that marks the end of the element. It is similar to the start tag but includes a forward slash (`/`) before the element name.

- **Content**: The actual content or text that appears between the start and end tags. This can include text, other elements, or multimedia content.

- **Attributes**: Optional additional information or properties that can be added to the start tag to modify the behavior or appearance of the element.

Here's an example of a simple HTML element:

```html
<p>This is a paragraph element.</p>
```

In this example:
- `<p>` is the start tag.
- `</p>` is the end tag.
- "This is a paragraph element." is the content.
- `<p>` is the element name (in this case, it represents a paragraph).
