Setting background color in css

How to Set Background Color with HTML and CSS

First thing you should know is that there are different types of HTML colors, such as Hex color codes, HTML color names, RGB and RGBa values, HSL colors, etc. To choose your preferred color use our Color Tools.

In this snippet, you can find many different ways of adding a background color. Let’s start from the easiest one.

Add the style attribute to the element

You can set a background color for an HTML document by adding style=»background-color:» to the element.

Example of setting a background color with the style attribute:

html> html> head> title>Title of the document title> head> body style="background-color:#1c87c9;"> h1>Some heading h1> p>Some paragraph for example. p> body> html>

Result

Some paragraph for example.

Add the CSS background-color property to the element

The background-color property is used to change the background color. Inserting it to the element you will have a full colored cover of the page.

Example of setting a background color with the CSS background-color property:

html> html> head> title>Title of the document title> style> body < background-color: #1c87c9; > style> head> body> body> html>

You can also add a background color to specific elements in your document. For example, let’s see how to change the color of the heading and paragraphs.

Example of adding a background color to specific elements:

html> html> head> title>Title of the document title> style> body < background-color: #e6ebef; > h2 < background-color: #8ebf42; > p < background-color: #1c87c9; > style> head> body> h2>Some heading with green background. h2> p>Some paragraph with blue background. p> body> html>

Let’s see another example, where we add a background color with a color name value to the element. We specify a RGB value for the , HSL for the , and RGBa value for the element.

Example of setting background colors with different color types:

html> html> head> title>Title of the document title> style> h1 < background-color: lightblue; > h2 < background-color: rgb(142, 191, 66); > p < background-color: hsl(300, 100%, 25%); > span < background-color: rgba(255, 127, 80, 0.58); > style> head> body> h1>Example h1> h2>Some heading with green background. h2> p>Some paragraph with blue background. p> span>Some paragraph for span> body> html>

Create a background with gradients

Gradient backgrounds let you create smooth transitions between two or more specified colors.

There are two types of gradient backgrounds: linear-gradient and radial-gradient.

In linear-gradient backgrounds, you can set a starting point for the colors. If you don’t mention a starting point, it will automatically set «top to bottom» by default.

Example of setting a linear-gradient background:

html> html> head> title>Title of the document title> style> #grad < height: 500px; background-color: blue;/* For browsers that do not support gradients */ background-image: linear-gradient(to right, #1c87c9, #8ebf42); > style> head> body> h1>Right to Left Linear Gradient background h1> div id="grad"> div> body> html>

The given example shows a linear gradient that starts from the left. It starts from blue, transitioning to green. Change it according to your requirements.

In radial gradient backgrounds, the starting point is defined by its center.

Example of setting a radial-gradient background:

html> html> head> title>Title of the document title> style> #grad < height: 500px; background-color: grey;/* For browsers that do not support gradients */ background-image: radial-gradient(#e6ebef, #1c87c9, #8ebf42); > style> head> body> h1>Radial Gradient Background h1> div id="grad"> div> body> html>

Create a changing background

You can create a background which will change its colors in the mentioned time. For that, add the animation property to the element. Use the @keyframes rule to set the background colors through which you’ll flow, as well as the length of time each color will appear on the page.

Example of creating a changing background:

html> html> head> title>Title of the document title> style> body < -webkit-animation: colorchange 20s infinite; animation: colorchange 20s infinite; > @-webkit-keyframes colorchange < 0% < background: #8ebf42; > 25% < background: #e6ebef; > 50% < background: #1c87c9; > 75% < background: #095484; > 100% < background: #d0e2bc; > > @keyframes colorchange < 0% < background: #8ebf42; > 25% < background: #e6ebef; > 50% < background: #1c87c9; > 75% < background: #095484; > 100% < background: #d0e2bc; > > style> head> body> h1>Changing Background h1> body> html>

The percentages specify the animation length mentioned in «colorchange» (e.g. 20s).

background-color

The background-color CSS property sets the background color of an element.

Try it

Syntax

/* Keyword values */ background-color: red; background-color: indigo; /* Hexadecimal value */ background-color: #bbff00; /* Fully opaque */ background-color: #bf0; /* Fully opaque shorthand */ background-color: #11ffee00; /* Fully transparent */ background-color: #1fe0; /* Fully transparent shorthand */ background-color: #11ffeeff; /* Fully opaque */ background-color: #1fef; /* Fully opaque shorthand */ /* RGB value */ background-color: rgb(255 255 128); /* Fully opaque */ background-color: rgb(117 190 218 / 0.5); /* 50% transparent */ /* HSL value */ background-color: hsl(50 33% 25%); /* Fully opaque */ background-color: hsl(50 33% 25% / 0.75); /* 75% opaque, i.e. 25% transparent */ /* Special keyword values */ background-color: currentcolor; background-color: transparent; /* Global values */ background-color: inherit; background-color: initial; background-color: revert; background-color: revert-layer; background-color: unset; 

The background-color property is specified as a single value.

Values

The uniform color of the background. It is rendered behind any background-image that is specified, although the color will still be visible through any transparency in the image.

Accessibility concerns

It is important to ensure that the contrast ratio between the background color and the color of the text placed over it is high enough that people experiencing low vision conditions will be able to read the content of the page.

Color contrast ratio is determined by comparing the luminance of the text and background color values. In order to meet current Web Content Accessibility Guidelines (WCAG), a ratio of 4.5:1 is required for text content and 3:1 for larger text such as headings. Large text is defined as 18.66px and bold or larger, or 24px or larger.

background

The background shorthand CSS property sets all background style properties at once, such as color, image, origin and size, or repeat method. Component properties not set in the background shorthand property value declaration are set to their default values.

Try it

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

/* Using a */ background: green; /* Using a and */ background: url("test.jpg") repeat-y; /* Using a and */ background: border-box red; /* A single image, centered and scaled */ background: no-repeat center/80% url("../img/image.png"); /* Global values */ background: inherit; background: initial; background: revert; background: revert-layer; background: unset; 

The background property is specified as one or more background layers, separated by commas.

The syntax of each layer is as follows:

• Each layer may include zero or one occurrences of any of the following values:
  • The value may only be included immediately after , separated with the ‘/’ character, like this: » center/80% «.
  • The value may be included zero, one, or two times. If included once, it sets both background-origin and background-clip . If it is included twice, the first occurrence sets background-origin , and the second sets background-clip .
  • The value may only be included in the last layer specified.

  Values

  See background-clip and background-origin . Default: border-box and padding-box respectively.

  See background-color . Default: transparent .

  The following three lines of CSS are equivalent:

  background: none; background: transparent; background: repeat scroll 0% 0% / auto padding-box border-box none transparent; 

  Accessibility concerns

  Browsers do not provide any special information on background images to assistive technology. This is important primarily for screen readers, as a screen reader will not announce its presence and therefore convey nothing to its users. If the image contains information critical to understanding the page’s overall purpose, it is better to describe it semantically in the document.

  Formal definition

  • background-image : none
  • background-position : 0% 0%
  • background-size : auto auto
  • background-repeat : repeat
  • background-origin : padding-box
  • background-clip : border-box
  • background-attachment : scroll
  • background-color : transparent
  • background-position : refer to the size of the background positioning area minus size of background image; size refers to the width for horizontal offsets and to the height for vertical offsets
  • background-size : relative to the background positioning area
  • background-image : as specified, but with url() values made absolute
  • background-position : as each of the properties of the shorthand:
    • background-position-x : A list, each item consisting of: an offset given as a combination of an absolute length and a percentage, plus an origin keyword
    • background-position-y : A list, each item consisting of: an offset given as a combination of an absolute length and a percentage, plus an origin keyword
    • background-color : a color
    • background-image : discrete
    • background-clip : a repeatable list of
    • background-position : a repeatable list of
    • background-size : a repeatable list of
    • background-repeat : discrete
    • background-attachment : discrete
