This time I will bring you how to use CSS to make a web page black and white, and use CSS to make a web page black and white. What are the precautions? The following is a practical case, let's take a look.

The method is as follows:

This CSS code can change the web page to black and white. Add the code to the top of the CSS to achieve plain decoration.

html{
filter: grayscale(100%);
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
-ms-filter: grayscale(100%);
-o-filter: grayscale(100%);
filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1);
}

If there is no

HTML tag in your page, remember to add it. You can add the following HTML5 tag, or change the html of the above CSS tag to body or other.

There are some websites where the color of FLASH

animation cannot be controlled by CSS filters. It can be done in the FLASH code of <object …> and Insert:

<param value="false" name="menu"/>
<param value="opaque" name="wmode"/>

If some pages with Flash still display color, or the Flash FLV player changes when the browser scroll bar is dragged up and down (such as Jian Wang 3, Jian Xia World official website divert page) , change Flash to JS output (SWFObject in this example):

<script type="text/javascript" src="/js/swf.js"></script>
<p id="video_content"></p>
<script type="text/javascript">
<!--
var video_player_so = new SWFObject("video-542.swf", "sotester", "439", "246", "7");
video_player_so.addParam("wmode", "opaque");
video_player_so.addParam("allowfullscreen","true");
video_player_so.addParam("allowscriptaccess","always");
video_player_so.write("video_content");
//-->
</script>
