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?

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:

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:

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:

ul {
    display: flex;
    justify-content: center; /* or other values like flex-start, flex-end */
}

8. Differentiate between an Ordered list and an Unordered list?

Aspect	Ordered List	Unordered List
Syntax	<ol> and <li> elements	<ul> and <li> elements
Marker	Displays numbers, letters, or custom characters	Displays bullets, squares, circles, or custom symbols
Purpose	Used for sequentially ordered content	Used for non-sequentially ordered content
Examples	1. Item 1 <br> 2. Item 2 <br> 3. Item 3	● Item 1 <br> ● Item 2 <br> ● Item 3
Default Style	Typically indented and with a margin	Typically indented with a bullet point marker
Accessibility	Useful for step-by-step instructions	Suitable for listing items without a specific order
Semantic Meaning	Implies a logical sequence	Implies a collection of related items

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:

<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). 10. what is difference between html & css?
