What to use to write css

CSS (Cascading Style Sheets) is a language used to describe document display styles, including fonts, colors, layouts, animations, etc. In front-end development, CSS is almost an indispensable part. Its role is to make the website more attractive and readable. So, how to write CSS? Let’s introduce it below.

1. Basic syntax

CSS syntax is very simple and mainly consists of selectors, attributes and attribute values. The selector is used to specify which elements need to apply the corresponding style, the attribute is used to describe the style attribute to be modified, and the attribute value is the value of the specified attribute.

For example, we can use the following code to modify the color of the text:

p{
  color: red;
}

Here, p is the selector, color is the attribute, and red is the attribute value. When applied to a

tag, the text will appear red.

2. Writing specifications

In order to improve the maintainability and readability of the code, we need to follow some CSS writing specifications. For example:

• Use indents and line breaks: Adding indents and line breaks to your styles can improve the readability of your code.
• Follow naming conventions: In order to facilitate other people’s understanding, CSS naming conventions should be followed uniformly. It is generally recommended to use the BEM (Block Element Modifier) ​​specification, which can make the code more readable and maintainable.
• Avoid overly complex selectors: The more complex the selector is, the lower the performance will be and it will not be conducive to maintenance.

3. Use browser compatibility prefixes

Different browsers may implement certain CSS properties differently, so you need to use browser compatibility prefixes . For example, if we want the text-shadow to take effect in all browsers, we can write it like this:

text-shadow: 1px 1px 1px #000;
-webkit-text-shadow: 1px 1px 1px #000;
-moz-text-shadow: 1px 1px 1px #000;
-ms-text-shadow: 1px 1px 1px #000;
-o-text-shadow: 1px 1px 1px #000;

Here, we add the browser compatibility prefix in front of text-shadow to ensure that all browsers can correctly Show text shadow effect.

4. Use CSS preprocessor

In large projects, handwriting pure CSS code will greatly increase the code volume and complexity. In order to reduce the occurrence of this situation, developers usually use CSS preprocessors such as Sass, Less or Stylus. The preprocessor allows developers to use advanced language features such as variables, nesting, and mixing to improve the efficiency and maintainability of CSS writing.

5. Use CSS framework

If you need to write a lot of CSS code when creating a website, consider using a CSS framework. Some common CSS frameworks include Bootstrap, Foundation, Materialize, etc. These frameworks provide a large number of CSS classes for developers to use directly, which can help developers quickly build an attractive website layout.

In short, CSS writing needs to follow certain specifications, and using some techniques and tools can improve writing efficiency and readability. Whether you are a beginner or an experienced developer, you can benefit from it.
