My First CSS Example

This is a paragraph.

Hello world!

Every element on the page will be affected by the style.

Me too!

And me!

Hello World!

Smaller heading!

This is a paragraph.

Hello World

rgb(255, 99, 71)

#ff6347

hsl(9, 100%, 64%)

Same as color name "Tomato", but 50% transparent:

rgba(255, 99, 71, 0.5)

hsla(9, 100%, 64%, 0.5)

Transparent Boxes

When using the opacity property to add transparency to the background of an element, all of its child elements become transparent as well. This can make the text inside a fully transparent element hard to read:

opacity 0.1

opacity 0.3

opacity 0.6

opacity 1 (default)

In addition to the predefined color names, colors can be specified using RGB, HEX, HSL, or even transparent colors using RGBA or HSLA color values.

This is a text inside a div element.

We are still in the div element.
