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.

Let's have look at the solution first:

<html>
 <head>
 </head>
 <body>
   <div class="content">
  <h1>A footer that stays at the bottom of the page</h1>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
</div>

<footer class="footer">

</footer>
 </body>
</html>

.content {
  min-height: calc(100vh - 70px);
  padding: 40px 40px 0 40px;
}

* {
  box-sizing: border-box;
}
footer {
  text-align: center;
  background: teal;
  color: white;
  line-height: 40px;
  padding: 0 15px;
}

## Explanation

The only line that we needed to add to the CSS is:

```css
min-height: calc(100vh - 70px);
```
We can see that the footer has a `line-height` of `40px` and a top/bottom padding of `15px`, so it should be `70px` high. We subtract that from the height of the entire page and set this value as the `min-height` of the content area.

Try adding more text to the content area and see what happens when the vertical scrolling begins to happen.
