In addition to using hexadecimal color codes, you can also use color names and RGB values. and HSL value to set. For example, the following code sets the background color of a div to blue:

.myDiv {
  background-color: blue;
}

  background-color: rgba(0, 0, 255, 0.5); /* 50% 透明度的蓝色 */
}

In addition to the background color, you can also set the text color of the div. The text color can be set using the color attribute in CSS. The specific syntax is as follows:

.myDiv {
  color: white;
}

where white is the color name, or other color names or color codes can be used to set it. Likewise, colors can also be represented using RGB values ​​or HSL values.

In addition to writing the color name or color code directly, we can also use the gradient effect in CSS to set the background color of the div. The gradient effect can also use the background attribute. The syntax is as follows:

.myDiv {
  background: linear-gradient(to right, #FF0000, #00FF00);
}

Among them, to right indicates that the gradient direction is from left to right, and #FF0000 and #00FF00 indicate the starting and ending colors of the gradient respectively. You can also set the radial gradient effect. The syntax is as follows:

.myDiv {
  background: radial-gradient(circle, #FF0000, #00FF00);
}

Among them, circle indicates that the shape of the radial gradient is a circle, and #FF0000 and #00FF00 indicate the starting and ending colors of the gradient respectively.

In short, it is very simple to use CSS to set the color of a div. You only need to use the background-color attribute or the background attribute. You can also flexibly use color names, color codes, RGB values, HSL values ​​and gradient effects to achieve it. Colorful style effects make web pages more colorful.
