Take full account of Web-based Course page accessible design, you can provide visit for everyone. However, the vast majority of visitors do not have problem in the physiological function, why do we have such a struggle? The most important reason is, stemming from humanitarian purposes-and this should be done.

The work that this article mainly does is as follows:(1)Trough the study and summarization on Web-based Courses page accessible design both domestic and foreign. On the one hand, we can understand the foreign research trend of Web-based Courses accessible design,on the other hand, can reveal the gap between domestic and foreign research on Web-based Courses page accessible design,and provide theoretical support for future research.(2)Study on theory and evaluation of Web-based Courses page accessible design. Theory basis mainly introduce inclusive education and general design; evaluation criteria discusses section508 standards of U.S. for web-based Internet and the intranet information and the application in, as well as web content accessibility guideline 1.0 of W3C/WAI.(3)Study on domestic Web-based Courses page accessibility.
