Attributes give extra information about an HTML element. They can change how an element behaves, looks, or functions. Attributes are written inside the opening tag and always follow the pattern:

<tagname attribute_name="attribute_value">some content</tagname>

Key Points

• Attributes can be required or optional: some elements need specific attributes (e.g., src for <img>), while others use optional ones for customization;
• Values are written in quotes: use "..." or '...' around the value to keep your code readable;
• Each tag supports different attributes: for example, <img> uses src and alt, while <a> uses href;
• You can add multiple attributes: simply separate them with spaces inside the opening tag.

• src tells the browser where the image is located;
• alt provides text shown if the image fails to load.

Sum Up

Every HTML element can include attributes to control its behavior:

• Tag defines the type of element;
• Attributes add extra details;
• Content is what appears between the tags (if the element has closing tags).

This is the core idea you'll use throughout the course when working with different elements.
