Increase the speed of web page loading-optimize web page picture files

Your web page must have pictures, and loading a web page often has the largest total image size, especially those colorful background pictures and major advertising pictures. Therefore, it is generally necessary to reduce the picture size as much as possible in the case of the same picture quality. In Photoshop we can try it with the option to save as a Web picture. Pictures are also available in several common file formats. For example, JPEG is generally used to store photos or full-color pictures, such as photos, screenshots and so on. GIF image format has fewer colors than JPEG, so it is suitable for making small pictures, such as making buttons, Logo, etc., and GIF supports dynamic effects. PNG is similar to GIF, but it is larger in size, supports more colors than GIF, and PNG supports transparent background. We can try saving pictures in a different format, such as replacing PNG and JPEG with GIF.

Speed up web page loading-pictures use height and width properties

Do you add height and width attributes to each image? These two properties allow the browser to know the length and width of the picture before loading the picture, and reserve the specified length and width to be displayed after the image is loaded. Without these two attributes, the browser also needs to process the page layout style again after reading the image successfully, which undoubtedly slows down the page loading speed. Therefore, in the case of fixed picture size, it is best to use upper length and width.

Speed up the loading of web pages-CSS file compression and slimming

DIV+CSS is now a fluent web layout, DIV defines elements, and CSS controls the display. So often we write CSS to one or more externally linked CSS files, and the CSS file code has many lines. We can use some CSS compression tools to remove unnecessary redundant content in CSS files, such as repeatedly defining styles, spaces, etc., to lose weight. Try using the CleanCSS tool to compress your CSS file.

Web page loading speed up-add a slash to the directory address (/)

If the visitor clicks to visit such a directory address: https://www.yisu.com/web, to open the index.html document in this directory. When the server receives the request, it takes some time to analyze whether it is a file or a directory. But if we add a slash (/) at the end, the server will know that you are accessing a directory address and then load the default document index.html or index.php directly. In this way, the server does not have to take the time to analyze the address, and also plays a certain role of acceleration.

Speed up web page loading-integrate CSS and JS files to reduce the number of HTTP requests

Today's web pages all have multiple images, links to CSS external files, and links to Javascript external scripts. So when visiting a web page, the browser needs to request these files from the server multiple times. There is a considerable time difference between the request and the load. Especially for some web pages with multiple small pictures and butcons, the browser needs to request as many small files as there are pictures, and more requests for these small picture files will significantly affect the loading speed of the web page. So we should try to piece together a small picture into a large PNG picture, and then display the icon through the coordinates. Requesting a large picture at a time is much faster than requesting a small picture multiple times. Similarly, it is best to integrate CSS and Javascript into a single file as much as possible to help speed up page loading.
