I have been writing CSS for so long, but most front-end ers do not write CSS code according to good CSS writing specifications, which will affect the reading experience of the code. Here is a summary of CSS writing specifications and CSS writing order for your reference
These are summarized with reference to some foreign articles and my personal experience. I think it is worth learning for front-end users who write CSS.
1. CSS writing order
1. Position attributes (position, top, right, z-index, display, float, etc.)
2. Size (width, height, padding, margin)
3. Text series (font, line-height, letter-spacing, color-text-align, etc.)
4. Background (background, border, etc.)
5. Others (animation, transition, etc.) )
2. CSS writing specifications
1. Use CSS About the writing standard order and naming rules of CSS properties
Some CSS properties can be abbreviated, such as padding, margin, font, etc. This streamlines the code while improving the user's reading experience.
2. Remove the “0” before the decimal point
3. Abbreviated naming
many Users like to abbreviate class About the writing standard order and naming rules of CSSs, but the prerequisite is that people can understand your naming before you can abbreviate it!
4.16 Color Code Abbreviation
Some color codes can be abbreviated, so we will try to abbreviate them as much as possible to improve user experience.
5 hyphen CSS selector naming convention
1). Long About the writing standard order and naming rules of CSSs or phrases can use a hyphen to About the writing standard order and naming rules of CSS the selector.
2). It is not recommended to use "_" underscore to About the writing standard order and naming rules of CSS CSS selectors. Why?
Press one less shift key when typing; Browser compatibility issues (such as using _tips selector naming, which is invalid in IE6) Able to distinguish JavaScript variable naming (JS variable naming uses "_" )
#6. Don’t use id randomly
id is unique in JS and cannot be used multiple times, but it can be reused using the class selector , In addition, the priority of id takes precedence over class, so id should be used as needed and not abused.
7. Add a status prefix to the selector
Sometimes you can add a prefix indicating the status to the selector to make the semantics clearer, such as the following figure The ".is-" prefix is added.
