I am working on making a div resize-able through a draggable handle. I am using Mouse event listener to achieve this functionality by following this solution. But however I would like show the preview boundary or something like outline before resizing the div, Is there any way to achieve this?
Basically I am try to achieve this https://www.unodc.org/misc/treaties/ext/examples/resizable/basic.html, One of the basic example that uses floating handles, it show's boundary on mouse-move events and the resizes it after. Is there a css property or something that I can use and then add some sort of callback function when events ends to resize it.
