The ultimate guide to HTML front-end interviews. Developed by FAANG engineers, practice with real-world interview questions and coding challenges. Get interview-ready in just a few hours.

In front-end interviews there’s a lot to cover. You have to study up on JavaScript, CSS, and then there’s HTML, and that’s the focus of this course.

This course compiles a comprehensive range of questions that you are most likely to be tested on during front-end interviews. There’s a healthy mix of both theory and applied coding challenges to give you hands-on experience.

You will start by going through several self-assessment exams to get an idea of what you’ll need to study up on. From there, you’ll go into interview questions on markup, semantics, and the DOM.

In the latter half of the course, you’ll focus on tags, elements, and attributes, forms, web APIs, and JavaScript fundamentals. In all, this course serves as a stand-alone guide for those who are starting to prepare for front-end interviews.

With 500+ quiz questions, 74 coding challenges, and 6 projects, you will have gained the confidence to go in and answer any question, no matter the complexity.

HTML for Front-end Interviews

## Test your understanding of the modern HTML5 markup

Please list the benefits of using HTML5 as opposed to the _earlier_ versions of HTML.

<p>Please list the benefits of using HTML5 as opposed to the <em>earlier</em> versions of HTML.</p>


HTML5 has made direct functionalities and provides access for a lot of things that in the past could only be used with third party plugins or separate programs.

1. New semantic elements that are purposefully made for their name use like `<header>` for header section, `<footer>` for footer section and other `<nav>`, `<article>`, `<section>` and so on.

2. Improved JavaScript API for geolocation, drag-and-drop, and media APIs.

3. Support for audio with `<audio>` tag, Video with `<video>` tag and `<canvas>` tag for embedding graphics directly into HTML5.
4. Enhanced support for multi-platform accessibility.

5. New form elements(`<time>`, `<url>` etc) and validation process.

Please define the usage of **data-attributes** in  HTML5.

<p>Please define the usage of <strong>data-attributes</strong> in  HTML5.</p>


Data attributes in HTML5 are used to embed custom data to an element which are quite helpful in developing Single Page Applications in modern web development.

**Coding demo**:
The following example illustrates this feature of HTML5:

.btn-group button {
  background-color: #FC736E; /* Orange background */
  border: 1px solid wheat; /* wheat border */
  color: white; /* White text */
  padding: 10px 24px; /* Some padding */
  cursor: pointer; /* Pointer/hand icon */
  width: 50%; /* Set a width if needed */
  display: block; /* Make the buttons appear below each other */
  font-family: Verdana, Geneva, Tahoma, sans-serif;
  text-align: center;
  text-decoration: none;
  font-size: 16px;
  align-self: center;
  
}

.btn-group button:not(:last-child) {
  border-bottom: none; /* Prevent double borders */
}

/* Add a background color on hover */
.btn-group button:hover {
  background-color: #1c164b;
}
h1{
  text-align: center;
  font-family: Verdana, Geneva, Tahoma, sans-serif;
}
h2{
    font-family: Verdana, Geneva, Tahoma, sans-serif;

}
