Where to Find the CSS Length Unit Flowchart and Newsletter on whatunit.com

The CSS length unit flowchart is the primary content on the whatunit.com homepage. Open the site and you land directly on the tool — there is no separate page or download required. The page also mentions a weekly newsletter signup for keeping up with CSS, and encourages sharing the tool if you find it useful.

What the homepage contains

The site is built around a single interactive decision aid titled "What CSS length unit should you use?" Its stated purpose is to help you decide which unit to use, and it presents that guidance as a flowchart rather than as prose.

Two elements sit alongside the flowchart:

• A weekly newsletter signup — described as a way to "keep on top of your CSS game."
• A share prompt — the page says that if you find the tool useful, sharing it would be appreciated.

How to operate the flowchart

The page gives three interaction instructions directly:

So the flowchart is pannable and zoomable rather than a fixed image. If the diagram initially appears larger or smaller than your viewport, that is expected — use the modifier key plus wheel to set a comfortable zoom level, then drag to reach the branch you need.

Getting the newsletter

The newsletter signup is referenced on the same page as the flowchart. The page evidence does not describe the signup form fields, confirmation flow, or what a subscription includes beyond the general framing of staying current with CSS. If you want it, look for the signup link or form on the homepage itself rather than a dedicated /newsletter route, since none is documented.

Practical notes

• The tool is a decision aid, not a reference table — you answer the flowchart's questions in sequence to arrive at a unit recommendation.
• Because the content is interactive, it works best on a device with a mouse or trackpad where the ctrl/cmd + wheel gesture is available.
• Nothing on the page indicates pricing, an account requirement, or a login gate for the flowchart itself.
