This stack creates quick modal popup windows in pure HTML, CSS and Javascript. Useful to display important messages or to get confirmation from the user. The lack of any libraries or frontend frameworks means that each popup weighs less-than 3KB! Perhaps the most unique feature of this popup stack is that you have complete, 100% access, to the entire codebase. Meaning you can use Modally as it is, or practice your coding skills and play with editing some of its code.
