Description
properties
that you can use to change the way an element looks on your page.
When you entered <h2 style="color: red">CatPhotoApp</h2>
, you were styling that individual h2
element with inline CSS
, which stands for Cascading Style Sheets
.
That's one way to specify the style of an element, but there's a better way to apply CSS
.
At the top of your code, create a style
block like this:
<style>Inside that style block, you can create a
</style>
CSS selector
for all h2
elements. For example, if you wanted all h2
elements to be red, you would add a style rule that looks like this:
<style>Note that it's important to have both opening and closing curly braces (
h2 {color: red;}
</style>
{
and }
) around each element's style rule(s). You also need to make sure that your element's style definition is between the opening and closing style tags. Finally, be sure to add a semicolon to the end of each of your element's style rules.
Instructions
h2
element's style attribute, and instead create a CSS style
block. Add the necessary CSS to turn all h2
elements blue.
Tests
tests:
- text: Remove the style attribute from your <code>h2</code> element.
testString: assert(!$("h2").attr("style"), 'Remove the style attribute from your <code>h2</code> element.');
- text: Create a <code>style</code> element.
testString: assert($("style") && $("style").length > 1, 'Create a <code>style</code> element.');
- text: Your <code>h2</code> element should be blue.
testString: assert($("h2").css("color") === "rgb(0, 0, 255)", 'Your <code>h2</code> element should be blue.');
- text: Ensure that your stylesheet <code>h2</code> declaration is valid with a semicolon and closing brace.
testString: assert(code.match(/h2\s*\{\s*color\s*:.*;\s*\}/g), 'Ensure that your stylesheet <code>h2</code> declaration is valid with a semicolon and closing brace.');
- text: Make sure all your <code>style</code> elements are valid and have a closing tag.
testString: assert(code.match(/<\/style>/g) && code.match(/<\/style>/g).length === (code.match(/<style((\s)*((type|media|scoped|title|disabled)="[^"]*")?(\s)*)*>/g) || []).length, 'Make sure all your <code>style</code> elements are valid and have a closing tag.');
