CSS style Writing code

CSS (Cascading Style Sheets) is a style sheet language used to describe the visual presentation of HTML elements. Its syntax is simple and easy to understand, and the code is easy to write.

Syntax structure

CSS style code consists of three parts:

• Selector: Specify to apply Styled HTML elements.
• Attributes: Set the visual properties of the element, such as color, font, size, etc.
• Value: Set the specific value of the attribute.

Writing Format

CSS style code is usually written in the following format:

<code>选择器 {
  属性1: 值1;
  属性2: 值2;
  ...
}</code>

Step Guide

1. Select the HTML element you want to style.
   For example, to style a paragraph element, you would use the selector p.
2. Add attributes and values.
   For example, to set the font of a paragraph to blue, you can add the attribute color and the value blue:

<code>p {
  color: blue;
}</code>

3. Repeat styling for other elements or attributes.
   You can add multiple style rules for different elements or attributes.

Notes

• Cascading: CSS style rules are applied in the order they are declared from back to front. Subsequent rules will override previous rules.
• Specificity: The stacking order of elements is determined by the specificity of their selectors. Selectors with higher specificity have higher priority.
• Browser Compatibility: Not all browsers interpret CSS code the same way. Compatibility should be considered when writing style code.

Example

The following CSS code will set the <h1> and <h2> elements The font is red and the font for paragraph elements is green:

<code>h1, h2 {
  color: red;
}
p {
  color: green;
}</code>
