Test your skills: Values and units
(Updated: 10/10/2023)
The aim of this skill test is to assess whether you understand different types of values and units used in CSS properties.
Note: If you get stuck, then ask us for help!
Task 1
In this task, the first list item has been given a background color using a hex color code. Your task is to complete the CSS using the same color in different formats, plus a final list item where you should make the background semi-opaque.
- The second list item should use RGB color.
- The third should use HSL color.
- The fourth should use RGB color but with the alpha channel set to
0.6.
You can find conversions for the hex color at this link. You need to figure out how to use the values in CSS.
Copy and paste the code below in a file named color.html.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8"/>
<title>Values and Units Task 1: color values</title>
<style>
body {
background-color: #fff;
color: #333;
font: 1.2em / 1.5 Helvetica Neue, Helvetica, Arial, sans-serif;
padding: 1em;
margin: 0;
}
ul {
list-style: none;
margin: 0;
padding: 0;
}
li {
margin: 1em;
padding: 0.5em;
}
.hex {
background-color: #86DEFA;
}
.rgb {
