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 have a look at the solution first:

.outer-bar { 
  top: 50px;
	height: 30px; 
	position: relative;
	background: #333;
	border-radius: 50px;
	padding: 10px;
}

.outer-bar > .progress-bar {
  display: block;
  height: 100%;
  width: 50%;
  border-top-right-radius: 8px;
  border-bottom-right-radius: 8px;
  border-top-left-radius: 20px;
  border-bottom-left-radius: 20px;
  background-color: rgb(24, 141, 55);
}

## Explanation

```css
.outer-bar { 
    top: 50px;
	height: 30px; 
	position: relative;
	background: #333;
	border-radius: 50px;
	padding: 10px;
}
```

We have used `top: 50px;` to push the progress bar downwards with a total height of `30` pixels. The position is set to `relative` because we want the `top` effect applied. The background color of the bar is set to `#333`. The rounded corners are the result of `border-radius`. The padding of `10` pixels is added across all the sides.


```css
.outer-bar > .progress-bar {
  display: block;
  height: 100%;
  width: 50%;
  border-top-right-radius: 8px;
  border-bottom-right-radius: 8px;
  border-top-left-radius: 20px;
  border-bottom-left-radius: 20px;
  background-color: rgb(24, 141, 55);
}
```

The `<span>` with `display: block` acts exactly like a div in this case. The height and width of the `progress-bar` are set to `100%` and `50%` to fulfill the requirements of the challenge. The `border-top-right-radius` and `border-bottom-right-radius` is set to `8px` as we want slight curves on these sides. The `border-top-left-radius` and `border-bottom-left-radius` is set to `20px` as we want sharp curves on these sides. The background color of the bar is set to `rgb(24, 141, 55)`.


The solution to the challenge of creating a progress bar using the background and border properties is discussed in this lesson.
