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.

## Explanation

```css
body {
  font: 1.2em / 1.5 Helvetica Neue;
}
```

The `font` shorthand property is used where `1.2em` is the `font-size`, `1.5` is the `line-height`, and the `font-family` is `Helvetica Neue`.

```css
* {
  box-sizing: border-box;
}
```

All the elements must have a `border-box` around them so that the `padding` and `border` are included in an element’s total `width` and `height`.

```css
.box {
  width: 90%;
  padding: 0.5em;
}
```

We have set the `width` of the outer div to `90%`, and a `padding` of `0.5em` is added along all the sides of the box.


```css
.float {
  margin: 15px;
  width: 150px;
  height: 150px;
  color: white;
  border-radius: 5px;
  background-color: steelblue;
  padding-top: 3em;
  text-align: center;
}
```

Both the boxes (One and Two) have a `height` and `width` of `150` pixels and a `steelblue` background color. The text `color` is set to `white`, and the text is aligned in the `center`. The text is pushed down `3em` using the `padding-top` property. For rounded corners, the `border-radius` is set to `5` pixels. The `margin` of `15` pixels is added around the boxes.  

```css
.float1 {
  float: left;
}
```

The div with value `One` is floating on the `left` side.

```css
.float2 {
  float: right;
}
```

The div with value `Two` is floating on the `right` side.

The solutions to the challenges based on the CSS float property are discussed in this lesson.
