CSS filters are not plug-ins of the browser and do not comply with CSS standards, however, Microsoft specifically developed and integrated a set of functions in the IE browser to enhance the browsing function.

I. Filter attributesIn fact, the filter is a simple transparency, but it is such a simple transparency, but because of its very good effect, so the application frequency is very high.
1. Alpha Channel
. Alpha {filter: alpha (opacity = 50) // indicates that the transparency is 50%}2. Blur (Fuzzy)
<span style="font-size:14px;">.blur{ filter:progid:DXImageTransform.Morcrosoft.blur(pixelradius=4,makeshadow=false);}</span>3. Transparent color

Although this filter is very powerful, it does not mean that PhotoShop is not good. The two have their own advantages and disadvantages. Photoshop can still create images for us.
