Is it possible to use only CSS to alter the background color of a fixed navbar once the user has scrolled past a specific point vertically? I am curious if this can be accomplished in CSS by targeting the ID of another element, or possibly its height?
Although I am aware of JavaScript methods to achieve this effect, I am interested in finding out if there is a way to do it solely with CSS. Thank you for your help!
To achieve this effect, you can create a simulation using gradients and the CSS property background-attachment:fixed.
Check out this example below:
.fixed {
height:100px;
width:100%;
position:fixed;
color:#fff;
}
body {
height:300vh;
background:
linear-gradient(#fff,#fff) 0 100px/100% 100% no-repeat fixed,
linear-gradient(to bottom, blue 300px, red 0) center/100% 100%;
}<div class="fixed">
this is a fixed navbar where the color will change after 300px of scroll
