1. Optimize CSS. We know that the appearance of CSS, so that the content and elements of the performance method of separation, the user opened the Web page with CSS design, CSS is generally downloaded users of the local computer, unlike the HTML element performance tag, each Web page will be called once, using CSS, only need one time! In addition, CSS in some places can replace the picture, which is why now advocate Div! However, using DW to write CSS, there will be some extra CSS code. CSS is too bloated, it will also affect the speed of the Web page, here is a tool cleancss for everyone to try, it is an online tool. The other is to hand-streamline the code, this does have this for beginners is indeed difficult, but, look at some of the simplified CSS skills of the article will help you, see more, also know that the code can be streamlined.

2. Optimize the picture. This is not a trick, through the software is done. I like to use PS, in PS, choose the format used to store the Web, and then choose the quality of the pictures and other options, the picture looks very clear, size and appropriate to save it.

3. Picture format problem. It is important to choose the correct picture format. JPG is generally used in photos or True color pictures, gif use flat color pictures, generally used for buttons or logo pictures, PNG and gif very similar, but is more support for some colors!

4. Picture long width marking problem. This problem is generally seen in HTML, some people often forget to write the picture long and wide.

5. In the URL to learn to use "/". When a user opens a URL that is not followed by "/", the server will determine what type of file or Web page, then you add a "/" behind the URL, then the server will know is a directory page, reduce loading time.

6. Reduce the number of responses to Web pages. The opening of the Web page, in fact, is a very complex process. From the Web application open, to the Web server response, compile, and so on, and then send back to the browser, before showing us the text and pictures, multimedia files and so on. So I'm going to try to reduce the number of responses, and now Ajax is doing well in this area. Of course, a static page is an exception, static pages pay more attention to the size of the picture and web design on the line.
