Remove Gray Filter from Web Page

Everytime when some important person deceases, most websites put on a gray filter to mourn.

Since it is a CSS trick, the filter can be removed by browser extension easily.

Install a browser extension like Stylus for Chrome, and add the following CSS style to the extension, the gray witchcraft shall be lifted for good:

Remove All filter

* {
    -webkit-filter: none !important;
    filter: none !important;
}

Remove Filter From HTML Tag Only

html {
    -webkit-filter: none !important;
    filter: none !important;
}
