CSS Formatting Full Guide: beautification, compression and prefix

1. What do you want to be glorified, compressed and verified?

The CSS is often mixed up in the daily "cleaning" of the front:

Focus on KiloCell of grammes Beautify + Minify: Toolbars Optional 2 spaces / 4 spaces / Tab Indent, enter left, and output right, display the number of characters, and support the reproduction of the results. Compressed Paths will ** delete / ... / Note** and tighten the sign next to the blank.

It is different from the full PostCSS / csssnano / Lightning CSS current line: the page is achieved as Lightweight rule for common handwritten CSS, for extreme entrapment, complex @ Rules, special characters in strings are manually reviewed. The separation of "quick-cleaning online" and "compression of authority to build pipelines" avoids false expectations.

A minute to a minute.

Compress or single-line style:

.btn{display:inline-flex;align-items:center;padding:10px 20px;background:#10b981;color:#000;border-radius:10px}
.btn:hover{background:#059669}

After aesthetic (4 spaces):

.btn {
    display: inline-flex;
    align-items: center;
    padding: 10px 20px;
    background: #10b981;
    color: #000;
    border-radius: 10px
}
.btn:hover {
    background: #059669
}

The eyes can be swept immediately to the border between the pseudo-declaration block. Note: Partially simple beautification to the last semicolon,@media The internal indentation level is handled more simply.Use diff before writing back to the warehouse.。

Rules relating to writing and formatting strong CSS

Declarant Blocks & Selector

• Each set begins with the selector.{ The first time I saw the story was in the video.} End.
• Declare as Properties: Value;, the semicolon should be decipherable before and after compression; It is usually a line for each declaration.
• Multiple selectors can use commas branches for review "who exactly matches".

Comment

• Standard Comment only / ... /，No, I'm not. //(Unless for preprocessors).
• A "licence header" or temporary after the compressor removes the comment / stylelint-disable / It's going to disappear. If a production package needs a license, it should be built into the configuration. preserve Or inject it alone.
• Page compression:To comment.。 Do not use this page to compress the scene "only want to leave blank but keep a license".

Vendor prefixes and sequences

History Properties -webkit-、-moz-、-ms- Wait for the prefix. Formatting Should not sort wrongly to change the layered intent It's hard to read, but when you write it by hand, you suggest:

1. Standard attributes are in the same logical group as prefixes, avoiding the insertion of unrelated statements in the middle.
2. The blog also shows how the government is doing this:Source-Cell Standard Properties, prefix to build, not online tool "smart prefix" (this page) Do not fill prefix）。
3. The compression prefix should still be in place; If the prefix is found to be missing, it is indicated that the entry touches the simple regular boundary on the string/note cutting, and the chain or segment processing is replaced.

/* Hands.Write兼Yon.Example：FormatBack仍ReactionsPor留各Okay. */
.box {
  -webkit-transform: translateX(4px);
  transform: translateX(4px);
}

Preprocessor and Modern Syntax:

ConclusionsPreprocessor source file is used for eco-friendly Prettier/Stylelint； This tool is suitable for quick collation of "text already CSS".

Colours and Formatting

It's usually not changed. #10b981 and rgb() is the equivalent of the choice. If you want to change between HEX/RGB/HSL, use color converter, do not expect the formatting tool "Choose-by-Colour"

3. Gorgeousization and compression in KiloCell: step by step

tools page:CSS Format。

1. Open tool。 Enter /tools/dev/css-formatter, confirm that the toolbar has indented indentation and "aesthetic code" "compression code".
2. Paste CSS. To Enter CSS Code Below or next to the "N" count.
3. Select the indent. Select 2/4 / Tab if it is necessary to match the warehouse; If the team forbids Tab, do not choose Tab and submit the results to Git.
4. Beautify。 The blogger says that the government is not a party to the law. Text with a line break and indentation on the right; Toast hint "code is beautified".
5. Check key with @rules. Scroll Output, Confirm -webkit- I'm not sure if I can.@media The parenthesis is paired.
6. Minify。 The timescale "compression code" needs to be deployed. The notes will be removed; Compares the number of characters entered/outputs to estimate the returns.
7. Copy。 Copying the results to the clipboard; Empty output does not copy.
8. Clear。 The first step is to take a "clean-up" when sensitive or unnecessary drafts are processed.

Capacity boundaries

• Do: Quick admiral common CSS, denoting compression, local character statistics, theme switching.
• Do not: Autoprefixer, DeathCode Elimination, Merge Same Selector, SCSS Compiler, and ensure consistency with csssnano bytes.
• Privacy: (b) Browser local processing; Still avoid posting an unopened whole station CSS to an untrustworthy shared session.

If you only need to be extremely condensed and the workflow fixed to "input the smallest volume", you can also use a separate type. CSS Minify Bookmarks; This page is suitable for a beautification/compression comparison of the same input.

4. Common problems and approaches

5. Real work landscape

scene A: Restore from View-Source style online

Paste single line CSS into →4 space-based beautification by searching for a selection and comparing the draft. Do not change the compression string directly. After the restoration was completed, the source library was based on the component CSS/CSS-in-JS, with only cross-references to the online code.

Scene B: Press third-party footage before you go online.

A statistical or chat plugin provides uncompressed CSS. - Is it suspicious to read it? * Selector or large font package references, which are then compressed by inlink or drop-off. Character statistics can be used as a rough indicator of whether it is worth being inlined.

C:Code Review style dispute

Each of them is beautified to the same indentation, then to the true difference in attributes. Take the "space" off the report noise. If there is a Prettier, which is the Prettier, the online tool only handles "temporary clips from the other side".

scene D: CSS from email HTML

Mail client to CSS supports breakup. First, you'll be a beauty, then you'll decide what properties you use. Formatting does not ensure compatibility of mail client; It just helps you read.

Scene E: Suspected that the manufacturer's prefix was removed from construction

Get construction product CSS beautification, search transform and -webkit-transform。 If the target browser still needs prefixes but the product is not, the Autoprefixer Brownerslist is repaired instead of handwritten prefixes to business source code.

scene F: screen with HTML "The Style is Not Active"

Use HTML to purge the class nest before you can be adorned in CSS. The Scrabble is 10 times more common than "need to compress" (see below).

Performance and engineering habits

• Transfer: The story is full of compressed + Gzip/Brotli; Only the spaces to go are still to open the HTTP compression.
• Cache: (a) The name of the document in Hashi; Change the line CSS to replace the URL.
• Critical path: Key CSS blocking rendering; Key critical routes, the rest packed.
• don't want The first one is a "supplied" document for production. The admiralization is left to development and miscalculation.
• Source Map： The formal compression is given to the construction with the Map so that the source can be mapd back with the error reported on the line.
• Repeated declaration: Formatting does not merge .a{color:red} and .a{color:red}； Repeat is a design/generation problem.
