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

## Challenge
Modify the following ordered list *programmatically* to use uppercase Roman numerals for the list items. The expected output is shown below:

code {
    color: #c7254e;
    background-color: #f9f2f4;
    border-radius: 4px;
  	padding: 2px 4px;
}

<html>
 <head>
   <title></title>
 </head>
 <body>
   <h1>Modifying HTML elements:</h1>
   <ol>
     <li>DOM manipulation is fun</li>
     <li>Access the <em>element node</em> associated with the HTML element using <code>document.querySelector()</code></li>
     <li>Use the element node's <em>properties</em> to modify the actual element.</li>
   </ol>
 </body>
</html>

var input = document.querySelector('ol');
input.setAttribute('type', "I");
