Without HTML

HTML is used to add structure and meaning to a web page. Without HTML, every web page would look like one giant block of plain text:

HTML Tags

HTML lets one mark off different elements of a page, such as paragraphs, headings and emphasized text. HTML does this with tags, which are special labels marked with pointy brackets <>. For example, a paragraph in HTML is created with <p> </p> tags:

<p>This is a paragraph.</p>

The paragraph starts with an opening <p> tag and ends with a closing </p> tag which is marked with a forward slash /. Most elements in HTML are marked with an opening tag at the beginning and a closing tag at the end.

Emphasis

Now that you can separate your text into paragraphs, let's look at one more HTML tag. To emphasize text, use the <em> tag. For example, this HTML:

Hello, <em>this is important!</em>

Will appear like this:

Hello, this is important!

HTML vs CSS

HTML tags are used to mark up meaningful elements on a page. To customize the exact appearance of elements, such as their specific size, color and spacing, you should use CSS, which will be covered later.

Challenges

Enter your HTML in the editor below to solve the challenge, and see how it would be displayed on the right. Note: the editor will automatically create closing HTML tags for you, which may sometimes need to be moved to a different position.
