A quick implementation of a 3 pane display with highlighting, hiding and resizable border actions.

Kindly inspired in the frontend-boilerplate put together by TJ Holowaychuk, this module can be tested by opening the index.html file in the dist folder or, if you want to try out anything:

npm install
npm run start

If you want to produce a stable build, updating dist folder contents run:

npm run build

• ctrl+l hides the leftmost pane, adding its size to the panel on its right, the center pane
• ctrl+r hides the rightmost pane, adding its size to the panel on its left, the center pane
• ctrl+h selects the hovered pane, turning it green

All actions are "toggable", which means when pressing the second time it will undo the previous action

• No pane should be smaller than 10% of the viewport width
• No pane should be bigger than 70% of the viewport width
• Viewport should be always 100% filled with the panes and helper borders

• limits are not being properly applied, which, width resize and hide combinations should produce unwanted behaviors
• borders lack better grab feel for the user
• applications' state are not immutable nor components properties are clean
• multi-row support incomplete
