HTML Elements & Tags

### What is an HTML Element? An HTML element is defined by a start tag, some content, and an end tag:

<tagname>Content goes here...</tagname>

Examples of HTML Elements - `<h1>My First Heading</h1>` - `<p>My first paragraph.</p>` - `<button>Click Here</button>`

Nested HTML Elements HTML elements can be nested inside other elements:

<div class="container">
  <h2>Subheading</h2>
  <p>Paragraph nested inside a container div.</p>
</div>

Empty / Self-Closing Elements Some elements do not have content or a closing tag, such as `<br>` (line break) and `<img>` (image):

<p>Line 1<br>Line 2 after line break</p>
<img src="logo.png" alt="Company Logo">
