Question

CSS

.block{
-moz-linear-gradient(left, #e5e5e5 0%, #000000 100%);
}

Change to

-moz-linear-gradient(left, #e5e5e5 50%, #000000 100%);

html

<div class="block" style="width:500px; height:500px;"></div>

I don’t want to replace all of the style.Because I need to give user choose 1-100
then only change the % ,so how to select the % element & change it ?

Answer 1

How about this:

var area = 'left';
var color1 = '#e5e5e5';
var percentage1 = '50%';
var color2 = '#000000';
var percentage2 = '100%';
$('.block').css('background-image', '-moz-linear-gradient(' + area + ', ' + color1 + ' ' + percentage1 +', ' + color2 + ' ' + percentage2  + ')');
