Background styling - Add any background to your ComboStrap component

Undraw My Documents


The background element defines and adds a background.

It's mostly used with bar component to create compelling landing page.

You can create cover or tile background with:

The background area is defined as being the content plus the padding


     opacity="0 to 1"


  • image is to use an image (raster or svg) as background
  • fill defines how the image takes the space of its container.
    • cover (default) - The image is scaled within its container and cropped, if necessary (ie responsive background)
    • tile: The image is repeated until the container is filled.
  • color: defines a background color - if you have set an image, the color value is seen while the image is loading.
  • pattern and pattern-color are used to define the css_pattern name and color respectively.
  • opacity brings depth level on color. Value goes from 1 (no opacity, default) to 0, completely opaque, not visible). By layer, below are typical values.
    • First: 0.15
    • Second: 0.3
    • Third: 0.45
    • Fourth: 0.6
    • Fifth: 0.75
    • Sixth: 0.9
  • scroll: the scroll effect - how the background is moving while scrolling
    • local: the image is moving with its container
    • fixed: the image stays at the same position on the screen
  • If you set more than one background, the first background in the list is the farthest on the stack.
  • The background area is the content plus the padding but not the margin.


You can set a background color with:

All color value (name and hex) described in the color page are supported.

Uniform Color

<note info>
<background color="light"></background>
==== Background Color ====
A info note with a bootstrap light color as background

The background-color attribute is just a short cut.

<note info background-color="#6FE2E9">
==== Direct Background  Color ====
A info note with the background-color attribute
Direct Background Color

A info note with the background-color attribute

Gradient Color

ComboStrap implements also a gradient color naming scheme in order to show a linear color gradient in the background.

If you want to have a gradient on your color, just add the gradient- prefix to a color value.

Example with a light gradient background.

<bar background-color="gradient-light" hero="md">
=== A gradient light slide ===
A gradient light slide

If you want to have full gradient customization, you can add a gradient css style in your theme

The below CSS style gradient generator may help you in this task.

Because the gradient generated a image, you can't use a gradient color and an image at the same time in a background element. You just need to add another background.
