I'm curious if I can use CSS to target the first url syntax below if a user is below a certain screen width.
For example, if a user's browsers is below 700px, I do not want to show the first background image (background.png) - just the second (background1.jpg).
<div class="right-header" style="background-image: url('/wp-content/uploads/2020/11/background.png'), url('/wp-content/uploads/2020/11/background1.jpg');">
