Use of the logo in the page, and use of the page icon

 

I have said that I want to sort out the content and share it with you for work reasons. Now, I have caught up with the Qingming house and shared it with you.

CSS sprite)
The so-called sprite graph is actually to combine several images into one. In this way, the content can be quickly transmitted and presented in a low-concurrency browser (reducing requests ).

• When using these images, You need to reference the entire image and then set the coordinates to the desired small image.
• In addition, images are grouped by color into multiple files. Each image has only one color, which makes each image smaller.
• Of course, this selects a suitable solution based on the current project. The following two attributes are used to process the sprite:

1 background-image: url (".../*. png"); 2 background-position: 0px 0px; 3 4/* Note: negative value of position. */

• > [Icomoon. io]
• > [Alibaba icon library]
• & Gt; [Font Awesome 3.0]
