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.
h2 element's style attribute, and instead create a CSS style block. Add the necessary CSS to turn all h2 elements blue.
h2 element.
testString: 'assert(!$("h2").attr("style"), "Remove the style attribute from your h2 element.");'
- text: Create a style element.
testString: 'assert($("style") && $("style").length > 1, "Create a style element.");'
- text: Your h2 element should be blue.
testString: 'assert($("h2").css("color") === "rgb(0, 0, 255)", "Your h2 element should be blue.");'
- text: Ensure that your stylesheet h2 declaration is valid with a semicolon and closing brace.
testString: 'assert(code.match(/h2\s*\{\s*color\s*:.*;\s*\}/g), "Ensure that your stylesheet h2 declaration is valid with a semicolon and closing brace.");'
- text: Make sure all your style elements are valid and have a closing tag.
testString: 'assert(code.match(/<\/style>/g) && code.match(/<\/style>/g).length === (code.match(/style elements are valid and have a closing tag.");'
