I'm trying to make the background (only the search bar) to be a backdrop blur background without blurring the whole background image behind it.


I've tried webkit filter: blur & filter: blur, but they both blur the whole body and not just make the transparent background of the search bar blurred.
Note: I'm not using a background image in the code below because I'll embed this code in an iframe, which the background before it will be an image.
EDIT: I have removed the domain name in the ORIGINAL code so it doesn't conflict in search results for that domain name. Thanks everyone for helping me fix this issue! You're amazing!

<script type="text/javascript">
function submitSearch() {
var siteSearchUrl = "https://*DOMAIN_NAME*/_/search?query="; // Replace with your site's search URL
var query = document.getElementById("search-query-input").value;
var url = siteSearchUrl + query;
if (typeof IE_fix != "undefined") {
// IE8 and lower fix to pass the http referer
var referLink = document.createElement("a");
referLink.href = url;
document.body.appendChild(referLink);
referLink.click();
} else {
window.open(url, "_blank");
} // All other browsers
}
function searchKeyPress(e) {
// look for window.event in case event isn't passed in
e = e || window.event;
if (e.keyCode == 13) {
document.getElementById("search-icon").click();
return false;
}
return true;
}
