Set background colors in html

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.

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

    Did you want to change the background color of that page using HTML? Unfortunately, with HTML 5, this is no longer possible in just HTML coding. Instead, you’ll need to use both HTML and CSS coding, which works even better. This wikiHow teaches you how to change the background color of a web page by editing its HTML and CSS.

    • Although the attribute for HTML to manage background color is gone, you can still use HTML with CSS to change your background color easily.
    • You’ll need a numeric code for the color you want if you want a specific color. If you don’t need a specific color, you can use words like «orange» or «light blue.»
    • When editing a web page with HTML and CSS, you can create a solid background, gradient, or changing background.

    Setting a Solid Background Color

    

    

    

    body  background-color: #d24dff; > 

    

    DOCTYPE html> html> head> style> body  background-color: #d24dff > style> head> html> 

    

    DOCTYPE html> html> head> style> body  background-color: #93B874; > h1  background-color: #00b33c; > p  background-color: #FFFFFF); > style> head> body> h1>Header with Green Backgroundh1> p>Paragraph with white backgroundp> body> html> 

    Creating a Gradient Background

    

    

    Understand the basic syntax of this process. When making a gradient, there are two pieces of information you’ll need: the starting point/angle, and the colors that the gradient will transition between. You can select multiple colors to have the gradient move between all of them, and you can set a direction or angle for the gradient. [2] X Research source

    background: linear-gradient(direction/angle, color1, color2, color3, etc); 

    

    html  min-height: 100%; > body  background: -webkit-linear-gradient(#93B874, #C9DCB9); background: -o-linear-gradient(#93B874, #C9DCB9); background: -moz-linear-gradient(#93B874, #C9DCB9); background: linear-gradient(#93B874, #C9DCB9); background-color: #93B874; > 

    

    html  min-height: 100%;> body  background: -webkit-linear-gradient(left, #93B874, #C9DCB9); background: -o-linear-gradient(right, #93B874, #C9DCB9); background: -moz-linear-gradient(right, #93B874, #C9DCB9); background: linear-gradient(to right, #93B874, #C9DCB9); background-color: #93B874; > 

    

    For example, not only can you add more than two colors, you can also put a percentage after each one. This will allow you to set how much spacing you want each color segment to have. Here’s a sample gradient that uses this principle:

    background: linear-gradient(#93B874 10%, #C9DCB9 70%, #000000 90%); 

    

    background: linear-gradient(to right, rgba(147,184,116,0), rgba(147,184,116,1)); 

    

    DOCTYPE html> html> head> style> html  min-height: 100%; > body  background: -webkit-linear-gradient(left, #93B874, #C9DCB9); background: -o-linear-gradient(right, #93B874, #C9DCB9); background: -moz-linear-gradient(right, #93B874, #C9DCB9); background: linear-gradient(to right, #93B874, #C9DCB9); background-color: #93B874; > style> head> body> body> html> 

    Creating a Changing Background

    

    

    -webkit-animation: colorchange 60s infinite; animation: colorchange 60s infinite; 

    

    @-webkit-keyframes colorchange  0% background: #33FFF3;> 25% background: #78281F;> 50% background: #117A65;> 75% background: #DC7633;> 100% background: #9B59B6;> > @keyframes colorchange  0% background: #33FFF3;> 25% background: #78281F;> 50% background: #117A65;> 75% background: #DC7633;> 100% background: #9B59B6;> > 

    

    DOCTYPE html> html> head> style> body  -webkit-animation: colorchange 60s infinite; animation: colorchange 60s infinite; > @-webkit-keyframes colorchange  0% background: #33FFF3;> 25% background: #78281F;> 50% background: #117A65;> 75% background: #DC7633;> 100% background: #9B59B6;> > @keyframes colorchange  0% background: #33FFF3;> 25% background: #78281F;> 50% background: #117A65;> 75% background: #DC7633;> 100% background: #9B59B6;> > style> head> body> body> html> 

    Community Q&A

    Use the background-size property inside of the «body» element. For example, «background-size: 300px 150px» makes the background 300 pixels wide and 150 pixels high.
