Ways to dynamically modify the CSS attributes of a webpage during the page load event

I'm looking to incorporate the

background:rgba(226, 93, 141, 0.76)
attribute into the body:after psuedo-element once my page has finished loading.

Below is my HTML and CSS code:

<style runat="server" id="myStyle" >
body:after{
    position:fixed;
    content:"";
    top:0;
    left:0;
    right:0;
    bottom:0;
    z-index:-1;
}
</style>

Is there a way for me to target the body:after element during the page load event?

Answer №1

Add a fresh class called 'active' and include it in the body element.

body:after{
    position:fixed;
    content:"";
    top:0;
    left:0;
    right:0;
    bottom:0;
    z-index:-1;
}

body.active:after{
    background:rgba(112, 201, 45, 0.89);
}

Next, implement jQuery following Faiz Ahmed's advice:

$(window).load(function() {
   $('body').addClass('active');
});

Answer №2

The issue has been resolved:

     protected void Load_Page(object sender, EventArgs e)
            {
                setStyle.InnerHtml = " body:after{ 
position:fixed;
content:'';
 top:0;
left:0;
right:0;
bottom:0;
z-index:-1;
background:rgba(226, 93, 141, 0.76)";
            }





<style runat="server" id="setStyle"  >

</style>
