What is this?
Elements are tags with content; attributes add extra info like href, src, class, and id.
Why should you care?
MarkupVerse links, images, and forms all depend on correct attributes.
See it live — copy this example
Save as demo.html and open in your browser, or use Run Example below.
<p id="intro" class="lead">MarkupVerse builds real sites.</p>
<a href="/pricing" title="See plans">Pricing</a>
<img src="logo.svg" alt="MarkupVerse logo" width="120">Run Example »

What happened?
- Attribute names are lowercase in HTML.
- Values go in quotes.
- id should be unique on the page.
Practice next
- Add class to the paragraph.
- Change href.
- Give the image a new alt.
- Add data-track="cta".
- Add rel="noopener" on a new-tab link later.
Remember
Tags + attributes. Quoted values. Unique ids.
MarkupVerse attribute drill
CTA link gets href + title.
Outcome: Click goes to /pricing with a tooltip.
