Color settings in html

In HTML programming, color setting is a very common operation. HTML provides a variety of ways to set the color of page elements. Here are some of them:

1. Use RGB values:

RGB is the English "Red" /Green/Blue" (red/green/blue), these three colors are mixed in different proportions to obtain a variety of colors. In HTML, we can use RGB values to set colors, for example:

红色背景

where, rgb(255, 0, 0) represents red, which represents the values of red, green and blue respectively, and the value range is Between 0 and 255. We can also use percentages to express it, for example:

红色背景

where rgb(100%, 0%, 0%) also represents red.

2. Use hexadecimal values:

In addition to RGB values, we can also use hexadecimal values to set colors. The hexadecimal value consists of the prefix # and 6 characters. Each two characters represents the value of a color channel. For example, #FF0000 represents red, where FF represents the value of the red channel, and the values of other channels are 0. We can also use abbreviations, such as #F00 for red.

3. Use predefined color values:

HTML also provides some commonly used predefined color values, such as red, green, blue, etc. We can use these color values directly in the style, for example:

红色文字

The above introduces several common color setting methods in HTML. Developers can choose the appropriate method to set the color of page elements according to actual needs. When using, you also need to pay attention to the position of the color settings and choose the appropriate color combination to achieve better visual effects.
