Creating web-page layouts with a constant line-height is difficult. LineheightJS adds horizontal stripes on any HTML document, enabling you to visualize where your elements get misaligned.
Create a bookmark pointing to the following address:
javascript:!document.lineheightjs?document.body.appendChild(document.createElement("script")).src="http://www.bravebolt.com/lineheightjs/lineheight.js":document.lineheightjs.toggle();void(0)
Clicking on it toggles the display of LineheightJS on (almost) any page.
LineheightJS uses PNGlib to generate the overlay image.
