1- How can you create a responsive image that scales with the screen size?
👉 Answer:
Use the max-width CSS property set to 100% to make an image responsive. This ensures that the image’s width adjusts to fit the container while maintaining its aspect ratio.
<img src="image.jpg" alt="A responsive image" style="max-width: 100%;">
2- What is the purpose of the <figure> and <figcaption> tags?
👉 Answer:
The tag is used to encapsulate media content, such as images or videos, along with an optional caption provided by the <figcaption> tag. It helps associate the media with its description.
<figure>
<img src="image.jpg" alt="A beautiful landscape">
<figcaption>A breathtaking view of nature.</figcaption>
</figure>
3- How can you add a background image to a webpage using HTML?
👉 Answer:
To add a background image to a webpage, you can use the background-image CSS property within the <style> tag or in an external CSS file.
<style>
body {
background-image: url("background.jpg");
background-repeat: no-repeat;
background-size: cover;
}
</style>
4- 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>
5- How can you embed an audio file in HTML?
👉 Answer:
To embed an audio file, use the <audio> element and specify the source file using the src attribute. You can include additional attributes like controls to add playback controls.
<audio src="audio.mp3" controls></audio>
6- Explain the purpose of the defer attribute in <script> tags.
👉 Answer:
The defer attribute is used to indicate that the script should be executed after the HTML content has been parsed. It helps improve page load performance by allowing other resources to load in parallel.
<script src="script.js" defer></script>
7- Explain the purpose of the pattern attribute in <input> tags.
👉 Answer:
The pattern attribute is used to specify a regular expression pattern that the input value must match. It is commonly used for form field validation.
<input type="text" pattern="[0-9]{3}-[0-9]{3}-[0-9]{4}" placeholder="XXX-XXX-XXXX">
8- How can you make an HTML element drag-gable?
👉 Answer:
To make an HTML element drag-gable, use the drag-gable attribute and set it to true. You can then define event handlers to control the drag-and-drop behavior.
<div draggable="true">Drag me!</div>
9- How can you create a sticky/fixed navigation bar in HTML?
👉 Answer:
To create a sticky/fixed navigation bar, use CSS to set the position of the navbar to fixed and specify a top or bottom value.
<style>
.navbar {
position: fixed;
top: 0;
width: 100%;
}
</style>
<div class="navbar">
<!-- Navigation links -->
</div>
10- How can you embed a YouTube video in HTML?>
👉 Answer:
To embed a YouTube video, use the <iframe> tag with the video’s embed code provided by YouTube.
<iframe
width="560"
height="315"
src="https://www.youtube.com/embed/VIDEO_ID"
frameborder="0"
allowfullscreen
>
</iframe>
