## 外掛說明

Combining HTML “minification” with cache and HTTP compression (**[WP Super Cache](https://wordpress.org/extend/plugins/wp-super-cache/)**,
or similar) will cut down your bandwidth and ensure near-immediate content delivery
while increasing your Google rankings.

This plugin will compress your HTML by shortening **URLs** and removing **standard
comments** and **whitespace**; including new lines, carriage returns, tabs and excess
spaces. Most importantly, by ignoring `<pre>`, `<textarea>`, `<script>` and Explorer
® `conditional comment` tags, **_presentation will not be affected_**.

## 安裝方式

 1. Download the plugin (zip file).
 2. Upload and activate the plugin through the “Plugins” menu in the WordPress admin.

## 常見問題集

  Installation Instructions

 1. Download the plugin (zip file).
 2. Upload and activate the plugin through the “Plugins” menu in the WordPress admin.

  Will this plugin slow down my page load times?

Yes, slightly. While you should be using **[WP Super Cache](https://wordpress.org/extend/plugins/wp-super-cache/)**
anyway, it will correct the issue.

  Will Internet Explorer conditional comments be removed?

No.

  Is this plugin HTML5-compatible?

Yes.

  Will having invalid HTML cause an issue?

Probably, however WordPress does a pretty good job of correcting invalid markup.
But honestly, it’s your job to make sure that your code doesn’t suck.

  Will this plugin interfere with my hash-based JavaScript navigation?

If the links in your HTML are _not_ hard-coded as hashes without the use of a script,
an issue could occur with URL shortening. If so, setting `$shorten_urls` on line`
21` of _libs/html-minify.php_ to `false` will fix that.

  My URLs have the “http:” and/or “https:” stripped??

This is totally fine and actually intentional. It’s standard and will not cause 
404s nor get in the way of your SEO, but it _will_ lower file size! You might be
interested in reading more about this technique, called **[scheme-relative URLs](http://paulirish.com/2010/the-protocol-relative-url/)**.

  Why does my compressed HTML have a space between most tags?

To preserve _rendered_ whitespace. One or more line breaks in your markup are rendered
as a single space in a web browser. Visual discrepancies would occur if those line
breaks were not converted to at least one space.

  How do I mark areas that should not be compressed?

While <pre>, <textarea> and <script> tags are automatically left uncompressed, you
can designate any code to be exempted from compression. Simply drop your content
between a pair of `<!--wp-html-compression no compression-->` comment tags. A picture
is worth a thousand words; so, check the **[screenshots](https://wordpress.org/extend/plugins/wp-html-compression/screenshots/)**.

  How do I compress the contents of <script> tags?

Until a settings page is created, you’ll have to edit the file from the “Plugins”
menu in the WordPress admin. Set `$compress_js` on line `21` of _libs/html-minify.
php_ to `true`. **This is not recommended** as this plugin is not yet ready to _properly_
compress inline scripts.

  Are you or have you thought of using HTML Tidy?

Since not every WordPress server supports the installation of PHP extensions, this
plugin does not currently make use of HTML Tidy. However, future releases may do
so.

  Will this plugin work for WordPress version x.x.x?

This plugin has only been tested with versions of WordPress as early as 3.2. For
anything older, you’ll have to see for yourself.
