Description from store

Rooler is a utility for automatically measuring on-screen graphics.

Not quite like every other measurement utility out there (though there are quite a few)- this one analyzes the graphics and automatically finds the edges. It's essentially an automatic ruler, for the web.

- Measures the bounds of graphics
- Measures the distance between graphics
- Allows ensuring correct positioning of elements, even in deeply nested element hierarchies.

It's quick and easy. Give it a shot.

You can also try Rooler in your browser at http://peteblois.github.io/rooler.js.

how to use?

色の差を判別して距離を測ってるようです。 手軽に素早く距離を測れてレイアウト確認がとても捗ります! 今まで苦労して小さい部分の距離を測るのに苦労していましたが、これなら一瞬です! ただ注意したいのが、色を判別して測っているので、 要素自体を判別しているわけではありません。 例えばあるボックスまでの距離を測りたい時に、 そのボックスに背景と同じ色のボーダーがあった場合、 そのボーダー分の距離は含まれません。 これはこれで便利ですが、このことは頭に入れておく必要があります。

Toller Ansatz, Abstände zu messen! Hier werden nicht die Abstände anhand von Elementen gemessen, sondern anhand von Farben. So kann man auch leicht die Zwischenabstände von Buchstaben und Co. herausfinden

This takes one of the best features of Xscope & reasons for using for buying it & brings it into the browser. It is brilliant!

This is now my measuring tool. Different than the others but more accurate. Helps you avoid the problem of getting the measurement spot right at a border by finding an edge itself. The boundary tool finds the boundaries of images or boxes. Love this thing!

Excellent for measuring relative sizes, even those not directly set by css but implicitly set the browser. I like it!
