Get a baseline grid overlay on your site in one painless, javascript-free step.
Here's an example demonstrating how to get a 24px baseline overlay on your site:
<link rel="stylesheet" href="http://basehold.it/24">
Easy, huh?
Specify a 6 digit hex code:
<link rel="stylesheet" href="http://basehold.it/24/DEEFFF">
Specify separate RGB values:
<link rel="stylesheet" href="http://basehold.it/24/255/42/85">
You can use Baseline to grab the image on it's own, if you'd rather apply it as a background in your own stylesheet.
Simple example:
html {
background-image: url(http://basehold.it/i/24); // 24px baseline
background-image: url(http://basehold.it/i/24/ff0000); // with Hex colour
background-image: url(http://basehold.it/i/24/255/0/0); // with RGB colour
}
