Action Tabs

The gallery has a choice of two thumbnail animations on hover - slide out captions and thumbnail scale.
Grid
The thumbnail grid has controls for setting the grid gap, and padding and the images can have a border. The caption is aligned left and centered vertically. The captions and the optional link icons can appear on hover when the grid is viewed on computers.
As can be seen from the demo the captions can run to two or more lines.
Container
The container has the option to be a two color gradient with adjustable angle and has controls for horizontal and vertical spacing.
Animation
The slide out captions and the thumbnail scale on hover animations are preset and are removed on mobile devices.
Gallery
The gallery has all the usual controls plus the option to change the overlay and caption background color and their opacity.
The caption inherits the font set for the grid captions and shares the same color as the controls.
The directional arrows have the option to be removed on touch devices where the slides can be swiped. There is a control to set the breakpoint at which the arrows are removed.
