I have been testing and modifying IE8 compatibility during this period of time. Because I am a programmer, I may have some limitations in some explanations. I hope you can give me more advice, the goal is to make progress together. Let's talk less about it. (Hope you can make it clear)

1. I have explained this question in the previous article about filter, but I will continue to add:

-Ms-filter: "progid: DXImageTransform. Microsoft. Alpha (opacity = 50)";/* IE8 */
Filter: "progid: DXImageTransform. Microsoft. Alpha (opacity = 50)";/* IE7 */

On ieblog, it is to meet CSS 2.1. Fortunately, these two do not recognize each other, so they can be written in one piece. In addition,-MS-filter must be written in front of the filter, because it seems a problem in IE7. Then FF is written in two ways: no supporter.
In IE8, we found that using filter on table th will cover all the border in the head. You can make a small experiment to see if there is anything.
Let me know the solution.

<! Doctype html public "-// W3C // dtd html 4.01 // EN" "http://www.w3.org/TR/html4/strict.dtd">

<Html>
<Head>
<Style>
Th {}{
-Ms-filter: "progid: DXImageTransform. Microsoft. gradient (enabled = 'true', startColorstr = white, endColorstr = gray )";
Border: 10px solid red;
}
</Style>
</Head>

<Body>

<Table>
<Tr>
<TH> Give Me A border </Th>
</Tr>
<Tr>
<TH> Give Me A border </Th>
</Tr>
<Tr>
<TH> Give Me A border </Th>
</Tr>
<Tr>
<TH> Give Me A border </Th>
</Tr>
</Table>

</Body>
</Html>
2. Regarding canvas, I am still the first to use this article. Some materials I found on the Internet are a new element of html5. they are mainly used to draw, synthesize images, or make simple animations. I want to know more about it.
Check it on the Internet. Here I want to say that IE8 does not support canvas. This is because it is a buzz on the Internet, and then MF connect says it will be supported in the future. I have no idea, but Google has
The ex-canvas.js can also be used as a canvas. I will not elaborate on it here

3. I wonder if you have used jsgraphics. JS, which can be used to dynamically draw circles, ovans, diagonal lines, broken lines, and polygons. However, we are reminded that IE8 is supported only in version 3.05.
The version is not supported, but it is actually slightly changed, so you can use it with confidence.

4. For CSS expressions, I would like to tell you that this stuff is not supported since IE8, so you should use it with caution at the very beginning.

5. Recommended a website for everyone, above is IE8 50 bugs, although it is an English site, but more useful yo (http://www.gtalbot.org/BrowserBugsSection/MSIE8Bugs)

The above are some of my ideas. If you have any benefits, you need a lot of recommendations. Haha ~~~ Sleeping ~~~~
