Baseline Grid

In practice, the baseline grid frequently doesn’t work for me because it is behind the sections, so if you set a background, it does not work.

I suggest you add the styling to the ::before element instead, to make sure it is always visible. See this code for reference:

body {
 position: relative;
}
body.elementor-editor-active::before {
 background-image:repeating-linear-gradient(90deg, var( --e-global-color-accent ), var( --e-global-color-accent ) 1px, transparent 1px, transparent 17px);
 content: "";
 position: absolute;
 top: 0;
 bottom: 0;
 width: 100%;
 z-index: 99999;
}
