I believe that anyone who has done applications using B/S method may encounter such a problem, how to facilitate, Beautifully realize report printing. If you use the browser's print menu to print, some useless things on the web page will be printed on the report, such as application menus, etc. Because selecting the print menu to print a web page will print out all the content in the web page. If your application has frames, the printed content will include the content in each frame, and the content you actually want is only part of it. Therefore, many applications can only complete the printing function in the background. What should we do in this situation? In fact, there are many ways to implement the web page printing function.
One way is to use professional printing tools, such as Crystal Reports. Friends who have used Visual Studio 5.0 must remember this tool, but the version at that time was only 4.0. The latest version is now version 9, and recent versions of Crystal Reports support WEB printing. The simplest method is to first use Crystal Reports to create a template, and then use ASP to call the prepared template with parameters. After Crystal Reports generates a report on the web page, it can be printed directly or transferred to other files that pass the comparison, such as Excel files. You can create very beautiful styles using Crystal Reports. The key lies in your ability to develop Crystal Reports. However, due to the high price of Crystal Reports, you can only afford it if the project is very profitable.
The second method is to purchase a third-party online printing control. The cost is cheaper than Crystal Reports, but the effectiveness and performance are different.
The third method is to use style sheets and JavaScript custom functions. Web page printing is achieved through style sheets and JavaScript, and the effect is acceptable. Here is an example for everyone to take a look at.The following is a detailed explanation of the printing function implementation:

Using scroll shadows, especially for mobile devices, is a subtle bit of UX that Chris has covered before. Geoff covered a newer approach that uses the animation-timeline property. Here’s yet another way.

Let’s run through a quick refresher. Image maps date all the way back to HTML 3.2, where, first, server-side maps and then client-side maps defined clickable regions over an image using map and area elements.
