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
Create an unordered list with *at least* three list items using only Javascript. The unordered list should show up in the HTML document and output correctly. A possible output is shown below:

body{
    background-color: midnightblue;
    color: rgba(255, 255, 255, 0.912);
    font-size: 18;
}

<html>
 <head>
 </head>
 <body>
   <h1>Creating Lists using JS and the DOM </h1>
 </body>
</html>

var ul = document.createElement('ul');
var li1 = document.createElement('li');
li1.innerHTML = "list element 1";
var li2 = document.createElement('li');
li2.innerHTML = "list element 2";
var li3 = document.createElement('li');
li3.innerHTML = "list element 3";

var content = document.querySelector('body');
content.appendChild(ul);
var content1 = document.querySelector('ul');
content1.appendChild(li1);
content1.appendChild(li2);
content1.appendChild(li3);

# Challenge
Create an unordered list with *at least* three list items using only Javascript. The unordered list should show up in the HTML document and output correctly. A possible output is shown below:

We use the `document.createElement()` method to create `ul` and `li` elements. The HTML DOM `innerHTML` property helps set the value or helps specify the HTML content of the `li` elements.

The `querySelector()` returns the first element within the document that matches the specified selector; in this case **line 9** the body element is returned, and **line 10** appends the `ul` as its child.

Similarly, `li1`, `li2`, `li3` (list items 1, 2, and 3 respectively) are appended as the `ul` element's children (**lines 11-14**). 

This is how you add elements to the HTML document using JavaScript and the DOM.


In this lesson, we will add elements to the HTML document using JavaScript and the DOM concept only.
