从中心开始的CSS线性渐变

Question

I am wondering if it is possible to do something like this with css gradients alone:

In this example the center orange would fade into grey in all directions. The black rectangle represents a div.

I couldn't find this on w3 schools, although there were various other gradient-related capabilities.

Answer 1

Isn't that exactly what radial gradient is all about?

background: #eded2f; /* Old browsers */
background: -moz-radial-gradient(center, ellipse cover,  #eded2f 0%, #474919 100%); /* FF3.6+ */
background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(0%,#eded2f), color-stop(100%,#474919)); /* Chrome,Safari4+ */
background: -webkit-radial-gradient(center, ellipse cover,  #eded2f 0%,#474919 100%); /* Chrome10+,Safari5.1+ */
background: -o-radial-gradient(center, ellipse cover,  #eded2f 0%,#474919 100%); /* Opera 12+ */
background: -ms-radial-gradient(center, ellipse cover,  #eded2f 0%,#474919 100%); /* IE10+ */
background: radial-gradient(ellipse at center,  #eded2f 0%,#474919 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#eded2f', endColorstr='#474919',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
