Is there any way to add transparency to images in CSS with -webkit-linear-gradient
on left, and right side of the image?
I have an image I want to add transparency - with pure CSS - on both side of it avoiding using any image editor like Photoshop, Gimp, etc. I have tried to use -webkit-linear-gradient
but it uses rgba() function to define color stops.
So this snippet
height: 200px;
background: -webkit-linear-gradient(left, rgba(255,0,0,0), rgba(255,0,0,1));
does this:
In this example the last parameter in the rgba() defines the transparency of the color. So far so good. If I put right
in the -webkit-linear-gradient
the image above would show the opposite. (You don't say?!)
I want somehow to merge the two, and create a gradient that goes to transparent on both side. Only not with gradient. With an image.
I also tried to work around with box-shadow
and radial-gradient
but I couldn't figure it out.
Is there any possible way to add transparency on left, and right side of an image using only CSS?
Example:
You could use a wrapper div and then use color stops:
div {
position: relative;
display: inline-block;
}
div:before {
content: "";
top: 0;
left: 0;
position: absolute;
height: 100%;
width: 100%;
background: -moz-linear-gradient(left, rgba(255, 255, 255, 1) 0%, rgba(255, 255, 255, 0) 49%, rgba(255, 255, 255, 1) 100%);
/* FF3.6+ */
background: -webkit-gradient(linear, left top, right top, color-stop(0%, rgba(255, 255, 255, 1)), color-stop(49%, rgba(255, 255, 255, 0)), color-stop(100%, rgba(255, 255, 255, 1)));
/* Chrome,Safari4+ */
background: -webkit-linear-gradient(left, rgba(255, 255, 255, 1) 0%, rgba(255, 255, 255, 0) 49%, rgba(255, 255, 255, 1) 100%);
/* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(left, rgba(255, 255, 255, 1) 0%, rgba(255, 255, 255, 0) 49%, rgba(255, 255, 255, 1) 100%);
/* Opera 11.10+ */
background: -ms-linear-gradient(left, rgba(255, 255, 255, 1) 0%, rgba(255, 255, 255, 0) 49%, rgba(255, 255, 255, 1) 100%);
/* IE10+ */
background: linear-gradient(to right, rgba(255, 255, 255, 1) 0%, rgba(255, 255, 255, 0) 49%, rgba(255, 255, 255, 1) 100%);
/* W3C */
filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#ffffff', GradientType=1);
/* IE6-9 */
