CSS writing specifications, ordering, and naming conventions

Reprint, Original source http://www.jb51.net/css/141575.html

Wrote so long CSS, but most of the front-end er are not in accordance with good CSS writing code to write CSS, this will affect the code reading experience, here summarizes a CSS writing specification, CSS Writing order for everyone to reference

These are references to some foreign articles and my personal experience summed up, I would like to write CSS front-end users are worth learning.

First, the 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. Other (animation, transition, etc.)

Second, the CSS writing code
1. Using CSS abbreviation properties
CSS Some properties can be abbreviated, such as Padding,margin,font, and so on, so that the refinement of the code at the same time can improve the user's reading experience.

2. Remove the "0" before the decimal point

3. Shorthand naming

Many users like abbreviated class name, but the premise is to let people understand your name to shorthand Oh!

4.16 Binary color code abbreviations

Some color code can be abbreviated, we try to abbreviate it, improve the user experience mainly.

5 hyphen CSS Selector naming specification

1). Long name or phrase you can use the middle horizontal line to name the selector.

2). It is not recommended to use the "_" Underline to name the CSS selector, why?

The input of the time to press a SHIFT key, browser compatibility issues (such as the use of _tips selectors named, in the IE6 is not valid) can be good to distinguish JavaScript variable naming (JS variable named "_")

6. Don't feel free to use the ID

ID in JS is unique, can not be used multiple times, and the use of class selector is reusable, and the priority of the ID priority and class, so the ID should be used on demand, and can not be abused.

7. Add a status prefix to the selector

Sometimes you can add a prefix to the selector to indicate the status, so that the semantics are clearer, such as adding the ". is-" prefix.

Third, CSS naming conventions (rules)

Iv. Matters needing attention::
