ie-css3.htc (let IE support box-shadow, rounded corners, text-shadow)

IE itself uses a shadow filter to achieve similar effects, and there are also some js and .htc hack files that can help you achieve this effect in IE. I can't try them all, so here I only introduce the one I have used.

How to use it is: download it and put it in your server directory

Write the following code in your 93f0f5c25f18dab9d176bd4f6de5d30e9c3bca370b5104690d9ef395f2c5f8d1:

<!--[if IE]>
<style type="text/css">img, #testdiv, .testbox{behavior: url(http://yourdomain.com/js/ie-css3.htc);}
</style>
<![endif]-->

In the blue part, enter the selector using the box-shadow attribute, and in the green part, enter the absolute path or relative path of ie-css3.htc. Anyway, you must ensure that it can be accessed.

Then this will be OK. But there are still a few things to note:

• After you use this htc file, as long as box-shadow, -moz-box-shadow or -webkit-box-shadow, IE will render.

• When using this htc file, you cannot write box-shadow: 0 0 10px red; but box-shadow: 0px 0px 10px red; otherwise it will fail in IE. .

• Alpha transparency in RGBA values ​​is not supported.

• Inset inner shadow is not supported.

• Shadow expansion is not supported.

• The shadow will only appear black in IE, no matter what other colors you set it to.

So, this script only allows IE to support some box-shadow values. If you have other better IE hacks script
