This article mainly introduces "the optimization scheme of the web front-end page". In the daily operation, I believe that many people have doubts about the optimization scheme of the web front-end page. The editor consulted all kinds of materials and sorted out a simple and easy-to-use operation method. I hope it will be helpful to answer the doubts of "the optimization scheme of the web front-end page". Next, please follow the editor to study!

1. Reduce HTTP requests to achieve performance optimization

The easiest way to improve response time is to reduce the number of HTTP requests.

2. Use font icons

Where we can use a lot of font icons, we can use font icons as much as possible. Font icons can reduce the use of a lot of pictures, thus reducing http requests. Font icons can also be used to set color, size and other styles through CSS.

3. Merge scripts and style sheets

Merging multiple stylesheets or script files into a single file can reduce the number of HTTP requests and thus shorten the effect time. However, merging all style files or script files may cause more styles or scripts to be loaded when a page is loaded, which may lead to an increase in downloads for people who visit only one (or more) pages of the site.

4. CSS Sprites technology

CSS Sprites is called css genie by many people in China, which is a way to deal with web pictures. It allows you to include all the sporadic pictures involved in a page into a large picture, and then use CSS background background positioning techniques to lay out the background of the page. In this way, especially for websites with a lot of pictures, if you can use css sprites to reduce the number of pictures, it will bring about an increase in speed.

5. Page rendering optimization

When writing front-end pages, put the CSS resource reference code in the header of the HTML file so that browsers can download CSS first and finish rendering the page as soon as possible! The reference code for JavaScript is placed at the bottom of the HTML file to prevent the loading and parsing of JS from blocking page rendering!

6. Optimization of mobile phone

When accessing the mobile terminal, there may not be WiFi, and occasionally the network speed will be relatively slow. Therefore, in order to speed up the loading of the page, it is necessary to minimize the loading resources of the first screen. Instead of the data on the first page, we can use asynchronous loading or scrolling loading.

7. Page cache optimization

Rational use of browser cache can greatly improve the loading speed of static resources in pages.

8. Picture optimization

It is more important on the mobile phone, try not to use it directly in the form of the original image, because it consumes a lot of traffic and takes longer to load! Using smaller pictures or compressed pictures can not only complete the loading as soon as possible, but also save traffic.

At this point, the study on the optimization scheme of the web front-end page is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
