css

.slider_overlay_menu
{
    float: right;
    position:relative;
}


.slider_overlay_menu:before
{
    -webkit-fliter:blur(5px);
}
.banner_questions
{
    float:right;
    width:825px;
    text-align:center;
    position:relative;
    display:block;
    margin-top:50px;
}

.overlay_menu input[type="submit"]
{
    margin-left:30px;
    vertical-align:middle;
}
.overlay_menu
{
    position: absolute;
    background: url('../images/banner_bg.png')no-repeat;
    height: 155px;
    overflow: hidden;
    width: 1007px;
    right: 0;
    z-index: 99998;
    bottom: 10px;
    padding:2%;
}

Actually, my slider is responsive, its width is 100%, and the overlay green shape is also position absolute which means when we increase the page size of the browser its changes it position.

Bottom line: I want to blur the content behind the green shape.

Just add -webkit-filter property for .overlay_menu like this:

.overlay_menu
{
    position: absolute;
    background: url('../images/banner_bg.png')no-repeat;
    height: 155px;
    overflow: hidden;
    width: 1007px;
    right: 0;
    z-index: 99998;
    bottom: 10px;
    padding:2%;
    -webkit-filter: blur(5px);
}
