The ultimate guide to CSS interviews, developed by FAANG engineers. Prep faster and get interview-ready in hours with battle-tested, real-world questions and a structured approach to styling and advanced concepts.

In front-end interviews there’s a lot to cover. You have to study up on JavaScript, HTML, and then there’s CSS, 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. This is an intermediate course with more than 250 coding challenges and multiple choice questions, so there’s plenty of opportunities to get your hands dirty.

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 styling such as text, colors, backgrounds, and display.

In the latter half of the course, you’ll focus on advanced concepts like Flexbox, block formatting, and working with SVG. In all, this course serves as a stand-alone guide for those who are starting to prepare for front-end interviews.

By the end of this course, you will have gained the confidence to go in and answer any question.

CSS for Front-end Interviews

# Solution Review

Let's go over the solution, step by step. HTML skeleton, first:

<html>
 <head>
 </head>
 <body>
  <nav class="dropdown">
    <button class="mainmenu">Products</button>
    <div class="submenu">
      <a href="#">Living</a>
      <a href="#">Garden</a>
      <a href="#">Kitchen</a>
    </div>
  </nav>
 </body>
</html>

We are using a `<nav>` tag to setup the navigation bar with the dropdown menu and unordered lists for the top and second level menus. Next, let's add some CSS:

.dropdown {
    display: inline-block;
    position: relative;
}
.mainmenu {
    border: none;
    padding:10px;
    margin-top:10px;
    cursor: pointer;
    background-color: olive;
    color: white;    
}
.mainmenu:hover {
    background-color: blue;
}
.submenu {
    display: none;
}

Here's what we've done so far:
* positioned the `<nav>` element 
* added a bit of padding an margin to the `mainmenu`
* hid the sub menus by setting `display: none;`
* changed the cursor for the `mainmenu` to a `pointer`
* changed the background and text colors for the `mainmenu`
* added a color change effect to the `mainmenu` item on hover 

Now, let's make it so that hovering on the `mainmenu` causes the sub menu to show up
