CSS Gradient Constants

I often visit this website, to create a nice gradient for my html elements.

Example of CSS that is created:

myElement {
    background: rgb(30,87,153); /* Old browsers */
    background: -moz-linear-gradient(top,  rgba(30,87,153,1) 0%, rgba(41,137,216,1) 50%, rgba(32,124,202,1) 51%, rgba(125,185,232,1) 100%); /* FF3.6+ */
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(30,87,153,1)), color-stop(50%,rgba(41,137,216,1)), color-stop(51%,rgba(32,124,202,1)), color-stop(100%,rgba(125,185,232,1))); /* Chrome,Safari4+ */
    background: -webkit-linear-gradient(top,  rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* Chrome10+,Safari5.1+ */
    background: -o-linear-gradient(top,  rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* Opera 11.10+ */
    background: -ms-linear-gradient(top,  rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* IE10+ */
    background: linear-gradient(to bottom,  rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* W3C */
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#1e5799', endColorstr='#7db9e8',GradientType=0 ); /* IE6-9 */
}

Now when I have multiple different gradients on my elements you can imagine that the CSS file gets quite messy.

Is there a way that I can define these gradients as constants or some other way to create a simple tidy solution?

So all I would have to do was something like this

myElement {
    background:GRADIENT_BLUE_GREEN;
}

Thanks! Any help is appreciated.

Like stated in other answers, declaring variables is not possible with pure css.

you can however, work around that and still achieve the desired tidy result using pure css - by using css animations.

you can define a static animation that will run once very fast and keep the last frame, and use the animation name as a variable for your elements for a tidy css:

.myElement {
  width: 200px;
  height: 100px;
  display: block;
  animation: GRADIENT_BLUE_GREEN 1ms 1 forwards;
}



/* you can define those in a separate file and link it where needed */

@-webkit-keyframes GRADIENT_BLUE_GREEN {
  to {
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(30, 87, 153, 1)), color-stop(50%, rgba(41, 137, 216, 1)), color-stop(51%, rgba(32, 124, 202, 1)), color-stop(100%, rgba(125, 185, 232, 1)));
  }
}
@-moz-keyframes GRADIENT_BLUE_GREEN {
  to {
    background: -moz-gradient(linear, left top, left bottom, color-stop(0%, rgba(30, 87, 153, 1)), color-stop(50%, rgba(41, 137, 216, 1)), color-stop(51%, rgba(32, 124, 202, 1)), color-stop(100%, rgba(125, 185, 232, 1)));
  }
}
/* define more keyframes per browser as needed */
<div class="myElement"></div>

You can make it easy on yourself with CSS Preprocessors but the actual file size is not going to change.

You can't do that with pure CSS, but fortunately you can use a-built-on CSS softwares like LESS and many other alternatives
