The Web Developer online test assesses knowledge of front-end web development skills (HTML, CSS, and JavaScript) through a series of live coding questions that test the ability to implement and style a user interface. Tasks on this test are executed inside the Google Chrome web browser.
The assessment includes solving work-sample tasks such as:
- Defining HTML elements and their attributes, and applying CSS styles to them.
- Handling user events and manipulating DOM to build responsive web pages.
- Serializing to/from JSON and making AJAX calls.
A good front-end web developer needs a solid understanding of HTML, CSS, and JavaScript in order to create modern, interactive, and responsive websites and user interfaces.
Sample public questions
A client has a web page with a series of tasks. They want to implement a reordering feature that behaves like the following example:
After performing the clicks shown in the animation above, the document's body should be:
<div>
<span>Read emails</span>
<button class="downButton" type="button">↓</button>
</div>
<div>
<span>Prepare presentation</span>
<button class="downButton" type="button">↓</button>
<button class="upButton" type="button">↑</button></div>
<div>
<span>Monthly report</span>
<button class="upButton" type="button">↑</button>
</div>
Implement the initialize function to apply the described functionality. The body tag will be prepopulated with the initial HTML which includes all the div, span, and buttons tags. The feature should work with any number of tasks.
A website features a menu with multiple menu items. However, the borders and spacing between and within these items are not properly styled.
Update only the CSS styles for the menu-item class so that the website looks like the image below:
All borders have a thickness of 2px.

What others say
Simple, straight-forward technical testing
TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
