Textarea-selection-bounds NPM

textarea-selection-bounds

Easily get the bounds of a selection in a textarea or text input element.

Motivation 💥

textarea-selection-bounds is a simple library that allows you to get the bounds of a selection in a textarea or text input element. It is written in TypeScript and has no dependencies. It is perfect to overlay content on top of a textarea or text input element that should follow the selection.

top & left are the coordinates of the top-left corner of the selection. They are relative to the window (fixed). width & height are the dimensions of the selection.

⚠️ Caution ⚠️: If you want to style an element that follows the selection, make sure to set the position of the element to fixed and use the top and left values from the bounds object.
