Review of the first tutorial

I have undergone an one-hour tutorial yesterday noon. The question asked meanwhile was whether it is a good idea to format HTML by using frame. It is no sense to say yes as everyone knows the reason.

First, the format of frame may not be supported by every single browser and leads to information hiden in some website.
Second, using frame could downgrade the capability of search engine. In other words, the search engine may sometimes search the subframe rather than an entire of the web site.
Third, using frame is hard to control CSS style, which is the core of the website's layout, thus no good for future maintainance.
Fourth, our current location may be confused by the frame function when we have had been performing page-backward/forward at the sub-frame level because a subframe itself could produce several subframe contents like the parent and child contents together, which is not supposed to appear, when clicking some internal hyperlinks inside the subframe.
Fifth, we always need to pay attention on the setting of frame width and height so that our web site could be displayed properly unaffected by the size of monitor and internet explorer.

Last but not the least, our helpful tutorial tutor,Ken, had introduced another technical issue concerning about using frame - the accessibility of the web design will be lessened. Web usability emphasizes every users should be able to gain access to a web. Taking blind users into consideration, some of the current speech recognition device used to read text of website could not read out the content from frame, or authentically. However, they should have the right to enjoy those privilege. This unuser-friendly function may be a vital reason for the market to give up frame.
