Test your skills: Selectors

The aim of this skill test is to help you assess whether you understand CSS selectors.

To complete these tasks you should only edit the CSS, not the HTML.

Task 1

To complete the task:

  1. Make the <h1> headings blue.
  2. Give <h2> headings a blue background and white text.
  3. Cause text wrapped in a <span> to have a font-size of 200%.

Your final result should look like the image below:

Text with the CSS applied for the solution to task 1.

html
<div class="container">
  <h1>This is a heading</h1>
  <p>
    Veggies es <span>bonus vobis</span>, proinde vos postulo essum magis
    kohlrabi welsh onion daikon amaranth tatsoi tomatillo melon azuki bean
    garlic.
  </p>
  <h2>A level 2 heading</h2>
  <p>
    Gumbo beet greens corn soko endive gumbo gourd. Parsley shallot courgette
    tatsoi pea sprouts fava bean collard greens dandelion okra wakame tomato.
    Dandelion cucumber earthnut pea peanut soko zucchini.
  </p>
</div>
css
body {
  font: 1.2em / 1.5 sans-serif;
}

You need to target the h1, h2 and span selectors to change their color or size.

css
h1 {
  color: blue;
}

h2 {
  background-color: blue;
  color: white;
}

span {
  font-size: 200%;
}

Task 2

To complete the task:

  1. Give the element with an id of special a yellow background.
  2. Give the element with a class of alert a 2px solid grey border.
  3. If the element with a class of alert also has a class of stop, make the background red.
  4. If the element with a class of alert also has a class of go, make the background green.

Your final result should look like the image below:

Text with the CSS applied for the solution to task 2.

html
<div class="container">
  <h1>This is a heading</h1>
  <p>
    Veggies es <span class="alert">bonus vobis</span>, proinde vos postulo
    <span class="alert stop">essum magis</span> kohlrabi welsh onion daikon
    amaranth tatsoi tomatillo melon azuki bean garlic.
  </p>
  <h2 id="special">A level 2 heading</h2>
  <p>Gumbo beet greens corn soko endive gumbo gourd.</p>
  <h2>Another level 2 heading</h2>
  <p>
    <span class="alert go">Parsley shallot</span> courgette tatsoi pea sprouts
    fava bean collard greens dandelion okra wakame tomato. Dandelion cucumber
    earthnut pea peanut soko zucchini.
  </p>
</div>
css
body {
  font: 1.2em / 1.5 sans-serif;
}

This tests that you understand the difference between class and id selectors and also how to target multiple classes on an item.

css
#special {
  background-color: yellow;
}

.alert {
  border: 2px solid grey;
}

.alert.stop {
  background-color: red;
}

.alert.go {
  background-color: green;
}

Task 3

To complete the task:

  1. Style links, making the link-state orange, visited links green, and remove the underline on hover.
  2. Make the first element inside the container font-size: 150% and the first line of that element red.
  3. Stripe every other row in the table by selecting these rows and giving them a background color of #333333 and foreground white.

Your final result should look like the image below:

Text with the CSS applied for the solution to task 3.

  width: 300px;
}

td,

Apply a pseudo-class (:first-child) and pseudo-element (::first-line) to the content. Style the :link, :visited, and :hover states of the a element, and create striped table rows using the :nth-child pseudo-class.

css
.container p:first-child {
  font-size: 150%;
}

.container p:first-child::first-line {
  color: red;
}

a:link {
  color: orange;
}

a:visited {
  color: green;
}

a:hover {
  text-decoration: none;
}

tr:nth-child(even) {
  background-color: #333333;
  color: white;
}

Task 4

To complete the task:

  1. Make any paragraph that directly follows an <h2> element red.
  2. Remove the bullets and add a 1px grey bottom border only to list items that are a direct child of the <ul> with a class of list.

Your final result should look like the image below:

Text with the CSS applied for the solution to task 4.

html
<div class="container">
  <h2>This is a heading</h2>
  <p>This paragraph comes after the heading.</p>
  <p>This is the second paragraph.</p>

  <h2>Another heading</h2>
  <p>This paragraph comes after the heading.</p>
  <ul class="list">
    <li>One</li>
    <li>
      Two
      <ul>
        <li>2.1</li>
        <li>2.2</li>
      </ul>
    </li>
    <li>Three</li>
  </ul>
</div>
css
body {
  font: 1.2em / 1.5 sans-serif;
}

This task checks that you understand how to use different combinators. Here's an appropriate solution:

css
h2 + p {
  color: red;
}

.list > li {
  list-style: none;
  border-bottom: 1px solid #cccccc;
}

Task 5

To complete the task, provide solutions for the following challenges using attribute selectors:

  1. Target the <a> element with a title attribute and make the border pink (border-color: pink).
  2. Target the <a> element with an href attribute that contains the word contact somewhere in its value and make the border orange (border-color: orange).
  3. Target the <a> element with an href value starting with https and give it a green border (border-color: green).

Your final result should look like the image below:

Four links with different color borders.

html
<ul>
  <li><a href="https://example.com">Link 1</a></li>
  <li><a href="http://example.com" title="Visit example.com">Link 2</a></li>
  <li><a href="/contact">Link 3</a></li>
  <li><a href="../contact/index.html">Link 4</a></li>
</ul>
css
body {
  font: 1.2em / 1.5 sans-serif;
}

ul {
  list-style: none;
  margin: 0;
  padding: 0;
}

li {
  margin-bottom: 0.5em;
}

a {
  display: block;
  padding: 0.5em;
}

a {
  border: 5px solid grey;
}

/* Add styles here */

  • To select elements with a title attribute we can add title inside the square brackets (a[title]), which will select the second link, which is the only one with a title attribute.

  • Target the <a> element with an href attribute which contains the word "contact" anywhere in its value and make the border orange (border-color: orange). There are two things we want to match here, the href value /contact and also ../contact. So we need to match the string "contact" anywhere in the value using *=. This will select the third and fourth links.

  • Target the <a> element with an href value starting with https and give it a green border (border-color: green). Look for an href value which starts with "https", so use ^= to only select the first link.

css
a[title] {
  border-color: pink;
}
a[href*="contact"] {
  border-color: orange;
}
a[href^="https"] {
  border-color: green;
}
