壓縮CSS YUI壓縮器

Question

任何人都知道需要哪一個選項來壓縮一行中的所有css。我使用的是一個叫做bwp-minify的wordpress插件，但是插件的css壓縮級別很低，我試圖通過YUICompressor.php來改變它。我嘗試將換行符更改爲0和100000，但都沒有影響。

是以下;

--line-break 
     Some source control tools don't like files containing lines longer than, 
     say 8000 characters. The linebreak option is used in that case to split 
     long lines after a specific column. It can also be used to make the code 
     more readable, easier to debug (especially with the MS Script Debugger) 
     Specify 0 to get a line break after each semi-colon in JavaScript, and 
     after each rule in CSS. 

源代碼：

Answer 1

你有使用--line-break選項試圖不？

當我使用YUI壓縮機，我不指定選項和輸出是在一行。

---

從你提供的，無論你叫

Minify_YUICompressor::minifyCss('/path/to.css'); 

您需要的line-break選項這樣設置-1源代碼來看：

Minify_YUICompressor::minifyCss('/path/to.css', array('line-break' => -1)); 

Answer 2

把下面的代碼開頭你的PHP腳本的

<?php header('Content-Type:application/javascript'); ?>
