1- What's the Point of the and Tags in HTML5?

👉 Answer:

The <header> tag is like a section's title, and the <footer> tag is like a closing. They make the top and bottom parts of a webpage.

<header>
  <h1>Welcome to Our Site</h1>
</header>

<footer>
  &copy; 2023 Our Site. All rights reserved.
</footer>

2- What's the Deal with the Placeholder in Tags?

👉 Answer:

The placeholder gives a hint or example for the input field. It's shown until you type something.

<input type="text" placeholder="Enter your name">

3- How Can You Turn Off an Input Field in HTML?

👉 Answer:

Use the disabled attribute to stop interaction with an input field.

<input type="text" name="name" disabled>

4- Why Hide Elements Using the Hidden Attribute in HTML?

👉 Answer:

The hidden attribute hides stuff on a webpage. You can use it with any HTML thing.

<p>This shows up.</p>
<p hidden>This stays hidden.</p>

5- Why Do We Use the Required Attribute in Form Inputs?

👉 Answer:

The required attribute says a field must be filled before sending a form.

<input type="text" name="name" required>

6- What's the Target Attribute in <a> Tags For?

👉 Answer:

The target attribute decides where a link opens. You can make it open in a new tab like this:

<a href="https://www.example.com" target="_blank">Open in new tab</a>

7- Why Use the Download Attribute in <a> Tags?

👉 Answer:

The download attribute makes a file download when you click a link, instead of opening it. You choose where to save it.

<a href="document.pdf" download>Download PDF</a>

👉 Answer:

Use <input> with type="checkbox" for a checkmark box.

<input type="checkbox" id="myCheckbox">
<label for="myCheckbox">Check me</label>

9- What's the Autocomplete Attribute in Tags?

👉 Answer:

The autocomplete helps your browser suggest things you typed before. You can turn it on or off.

<input type="text" name="email" autocomplete="off">

10- What's the Use of the Tag in HTML5?

👉 Answer:

The <nav> tag is like a menu for a webpage. It helps you move around the site.

<nav>
  <ul>
    <li><a href="#home">Home</a></li>
    <li><a href="#about">About</a></li>
    <li><a href="#contact">Contact</a></li>
  </ul>
</nav>
