Meta-HTML elements that are easily overlooked

With the popularity of his web editor such as FrontPage and Dreamweaver, it is not a dream to be able to do a Web page with a professional level without knowing HTML. But none of these home page makers can generate a good head on their own, which requires us to understand the elements that are available in.
< Title > is already well known, and here we are looking at another important element in the head < Metab >.
First of all, Meta can tell the browser page to identify the type of file and language type, for example, we want to let the browser identify the htm/html type of the Simplified Chinese network, we can write:
< Meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">
Second, meta can allow some search engines to search your Web page:< Meta name= "description" content= "page description text" > < Meta name= "Keywords" content= "page keyword" &G T
If the basic use of these two usage meta is also the code that can be generated by FrontPage and so on, the following usages are not possible for these visual editors:
1. Through meta you can allow a page to pass a certain time, automatically go to another page or site, such as:
< Meta http-equiv= "Refresh" content= "6; url=http://www.computerworld.com.cn "> Content 6 indicates the time in seconds.
2. Meta allows you to enter the page with some special effects, the specific application is as follows:
< meta http-equiv= "Page-enter" content= "Revealtrans (duration=5.0,transition=n)" > where the value range of n is 0-23, the specific meaning is as follows:
0 Rectangle Shrink 1 Rectangle enlarge 2 Round Shrink
3 Circular enlargement 4 down to upper 5 top to bottom
6 left to right 7 right to left 8 vertical Blinds

18 upper right to lower left 19 top to bottom right down 20 left to upper right
21 horizontal bar 22 Vertical bar 23 above 24 random selection of a

It should be noted that these special effects are only valid for new pages that are entered in top.
Just write the above to < head >, and your Web page will certainly be impressive.
