About this tool

IconVault's Box Model Visualizer makes the CSS box model click for real: sliders control content size, padding, border and margin, with uniform or per-side values, while a live color-coded diagram labels every layer and pixel measurement. Below it you get the border-box and outer totals plus copy-ready CSS.

Everything is free and runs fully in your browser, so it is a great companion when layouts do not behave: see exactly which layer is pushing your element around before you change the code.
