My First CSS Example

This is a paragraph.

Hello World

Same as color name "Tomato":

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)

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.

CSS background-color example!

This is a text inside a div element.

This paragraph has its own background color.

We are still in the div element.

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)

The border-style Property

This property specifies what kind of border to display:

A dotted border.

A dashed border.

A solid border.

A double border.

A groove border.

A ridge border.

An inset border.

An outset border.

No border.

A mixed border.

The border-width Property

This property specifies the width of the four borders:

Some text.

Note: The "border-width" property does not work if it is used alone. Always specify the "border-style" property to set the borders first.

The border-color Property

This property specifies the color of the four borders:

A solid red border

A solid green border

A dotted blue border

Note: The "border-color" property does not work if it is used alone. Use the "border-style" property to set the borders first.
