body {
background-image: url("background.jpg");
background-repeat: no-repeat;
background-size: cover;
}

23- How can you create an unordered list with custom bullet points using HTML?
Answer:
You can customize the bullet points of an unordered list using CSS by assigning a specific image or shape to the list-style-image property.

The <progress> element represents the progress of a task or process, providing a visual indication of the completion percentage.
<progress value="50" max="100"></progress>
25- How can you create a responsive video that adjusts to different screen sizes?
Answer:
To create a responsive video, use the max-width CSS property and set the height to auto. Wrap the video element in a container to maintain its aspect ratio.
<style>
.video-container {
max-width: 100%;
height: auto;
}
</style>
<div class="video-container">
<video src="video.mp4" controls></video>
</div>
26- Explain the purpose of the autocomplete attribute in <input> tags.

The autocomplete attribute allows the browser to suggest or remember previously entered values for an input field. It can be set to on or off.
<input type="text" name="email" autocomplete="off">
27- How can you create a tooltip for an element using HTML?
Answer:
To create a tooltip, you can use the title attribute on an HTML element. When the user hovers over the element, the tooltip text will be displayed.
<a href="#" title="This is a tooltip">Hover me</a>
28- What is the purpose of the <time> element in HTML5?
Answer:
The <time> element represents a specific point in time or a duration. It helps provide semantic meaning to dates and times on a webpage.
<p>My birthday is on <time datetime="1990-05-15">May 15th</time>.</p>
29- How can you disable the browser’s default form validation in HTML?
Answer:
Use the novalidate attribute on the <form> tag to disable the browser’s default form validation. This allows you to implement custom validation logic.
<form novalidate>
<!-- Form fields -->
</form>
30- Explain the purpose of the meter element in HTML5.
