Popper vs. Screenfull.js vs. Sencha Ext JS vs. python-sql Comparison Chart

Positioning tooltips and popovers are difficult. Popper is here to help! Given an element, such as a button, and a tooltip element describing it, Popper will automatically put the tooltip in the right place near the button. It will position any UI element that "pops out" from the flow of your document and floats near a target element. The most common example is a tooltip, but it also includes popovers, drop-downs, and more. All of these can be generically described as a "popper" element. Click on the dots to place the tooltip. There are 12 different placements to choose from. Pure CSS poppers will not be prevented from overflowing clipping boundaries, such as the viewport. It will get partially cut off or overflows if it's near the edge since there is no dynamic positioning logic. When using Popper, your popper will always be positioned in the right place without needing manual adjustments.
