小技巧给网页减肥，让网站提速。

1. 使用合理的编码技术：减少网页中不必要的字符，使用Gzip/ZIP等压缩软件，减少网页文件大小，减少HTML文件中标签、空格环节，替换静态资源为数字资源，如图片替换成 Base64 码。 2. 压缩Javascript和CSS文件：Javascript和CSS文件有一些冗余语句可以被压缩，将其进行压缩可以有效减少文件大小，减少网页加载的时间。 3. 合并Javascript和CSS文件：将多个Javascript和CSS文件合并为一个，减少浏览器发出的请求次数和页面文件大小，提高加载速度。 4. 去掉失效的链接：在网页中添加的失效链接不但无用，而且还会造成加载时间变长。 5. 选择合适的图片格式：使用 JPEG 和 PNG 图片格式能够显著减少文件大小。 6. 减少不必要的HTTP请求：浏览器加载一个页面时，为了请求脚本、图片等资源，需要在浏览器与服务器之间发出多次请求，这些请求都会占用一定的带宽资源，所以减少不必要的HTTP请求，也能提高网站加载速度。 7. 使用Content Delivery Network(CDN)：CDN 是一种将网站资源分散到全球多个节点的网络，可以大大减少用户与网站服务器之间的距离，从而加快网页的加载速度。
