Measuring Ruler

The plugin is designed to measure the height, width and margins of elements on the page during the preview when editing. It also shows the absolute and relative positions of elements.
In auto-correction mode, the program can automatically detect the borders of elements and correct inaccuracies in cursor positioning. Auto-correction occurs at the end of the measurement.
The plugin does not affect the appearance and html code of the page when its published.
