Css gradients and background image

CSS Gradients

CSS gradients let you display smooth transitions between two or more specified colors.

CSS defines three types of gradients:

• Linear Gradients (goes down/up/left/right/diagonally)
• Radial Gradients (defined by their center)
• Conic Gradients (rotated around a center point)

CSS Linear Gradients

To create a linear gradient you must define at least two color stops. Color stops are the colors you want to render smooth transitions among. You can also set a starting point and a direction (or an angle) along with the gradient effect.

Syntax

Direction — Top to Bottom (this is default)

The following example shows a linear gradient that starts at the top. It starts red, transitioning to yellow:

Example

Direction — Left to Right

The following example shows a linear gradient that starts from the left. It starts red, transitioning to yellow:

Example

Direction — Diagonal

You can make a gradient diagonally by specifying both the horizontal and vertical starting positions.

The following example shows a linear gradient that starts at top left (and goes to bottom right). It starts red, transitioning to yellow:

Example

Using Angles

If you want more control over the direction of the gradient, you can define an angle, instead of the predefined directions (to bottom, to top, to right, to left, to bottom right, etc.). A value of 0deg is equivalent to «to top». A value of 90deg is equivalent to «to right». A value of 180deg is equivalent to «to bottom».

Syntax

The following example shows how to use angles on linear gradients:

Example

Using Multiple Color Stops

The following example shows a linear gradient (from top to bottom) with multiple color stops:

Example

The following example shows how to create a linear gradient (from left to right) with the color of the rainbow and some text:

Example

Using Transparency

CSS gradients also support transparency, which can be used to create fading effects.

To add transparency, we use the rgba() function to define the color stops. The last parameter in the rgba() function can be a value from 0 to 1, and it defines the transparency of the color: 0 indicates full transparency, 1 indicates full color (no transparency).

The following example shows a linear gradient that starts from the left. It starts fully transparent, transitioning to full color red:

Example

Repeating a linear-gradient

The repeating-linear-gradient() function is used to repeat linear gradients:

How to Add Both a Background Image and CSS3 Gradient to the Same Element

CSS gradients are used for styling elements. They display smooth transitions between two or more defined colors. But have you ever tried to combine a CSS3 gradient and background image on the same element? If no, then this snippet is for you.

Solutions with CSS properties

You can combine a background-image and CSS3 gradient on the same element by using several backgrounds.

In our example below, we set the height and width of our and add a background. Then, we set the background image fallback using the “url” value of the background-image property. Finally, we set a background image and gradient for browsers that can deal with them. Also, set the background-size to «100%».

Example of using several backgrounds on the same element:

html> html> head> title>Title of the document title> style> div < height: 150px; width: 150px; background: lightgreen; background-image: url("/build/images/emojin-01.svg");/* fallback */ background-image: url("/build/images/emojin-01.svg"), linear-gradient(lightgreen, lightblue); background-size: 100%; > style> head> body> div> div> body> html>

Result

You can get a similar result by setting multiple background images. The first defined background image will be on the top, and the last defined one will be on the bottom.

In the following example, we use the «inline-block» value of the display property for our and set its background and background-size . Then, we add background images.

Example of combining a background-image and gradient on the same element with several background images:

html> html> head> title>Title of the document title> style> span < display: inline-block; height: 150px; width: 150px; background: #eb01a5; background-size: contain; background-image: url("/build/images/emojin-01.svg"), linear-gradient(pink, purple); background-image: url("/build/images/emojin-01.svg"), -webkit-gradient(linear, left top, left bottom, from(pink), to(purple)); background-image: url("/build/images/emojin-01.svg"), -moz-linear-gradient(top, pink, purple); > style> head> body> span> span> body> html>

If you want the image to be displayed above the gradient, put the URL before the gradient.

Example of displaying the image above the gradient:

html> html> head> title>Title of the document title> style> .background-gradient < background: url('/build/images/logo-color-w3.png') no-repeat, -moz-linear-gradient(135deg, #6ec575 0, #3b8686 100%); background: url('/build/images/logo-color-w3.png') no-repeat, -webkit-gradient(135deg, #6ec575 0, #3b8686 100%); background: url('/build/images/logo-color-w3.png') no-repeat, -webkit-linear-gradient(135deg, #6ec575 0, #3b8686 100%); background: url('/build/images/logo-color-w3.png') no-repeat, -o-linear-gradient(135deg, #6ec575 0, #3b8686 100%); background: url('/build/images/logo-color-w3.png') no-repeat, -ms-linear-gradient(135deg, #6ec575 0, #3b8686 100%); background: url('/build/images/logo-color-w3.png') no-repeat, linear-gradient(135deg, #6ec575 0, #3b8686 100%); height: 500px; width: 500px; background-position: center; > style> head> body> div class="background-gradient"> div> body> html>

In the next example, we set the width and height of the and specify both the background-image and gradient through the background property.

Example of combining a background image and gradient with the background property:

html> html> head> title>Title of the document title> style> div < width: 100%; height: 100px; background: url("/build/images/logo-color-w3.png") no-repeat left top, linear-gradient(#F7CFB6, #F08E86); > style> head> body> div> div> body> html>

In our last example, we combine the background image and gradient in the same way but use the «center» value. Also, we set the background-size to its «contain» value.

Example of combining the background image and gradient:

html> html> head> title>Title of the document title> style> div < width: 100%; height: 100px; background: url("/build/images/emojin-01.svg") no-repeat center, linear-gradient(135deg, lightgreen 0, lightblue 100%); background-size: contain; > style> head> body> div> div> body> html>
