I haven’t done any art work for a long time. In the front-end time, the teacher of a small website in the school needed the overall green style of the website, but they could not provide relevant materials, so the project has been delayed and the requirements cannot be determined. The basic functions of the backend are already in place, and I am just waiting for the page. I originally wanted to learn other things and consolidate some basics of Java, but it is still uncomfortable for me to delay this matter. The example of the security framework is not easy to make, so I decided to summarize the CSS filters I have recently learned. CSS filters are more handsome and can replace some of the effects that can only be achieved with PS, but their shortcomings are also obvious and not all browsers support them. But considering that IE6, 7... still occupy a large market share, there is a need to learn. There is no shortage of knowledge about CSS filters on the Internet, but most of them are lengthy or not comprehensive enough. Now, combining my own examples and online information, my learning experience is summarized as follows. After all, I am not a professional artist, so this essay is basically for beginners to help them master it quickly. Also understand what current CSS can do. In order to enrich the content, the source code of jQuery to implement pop-up layer effects is given.
