/*
TOUCH-CONTROLS.CSS

On-screen controls for phones and tablets. The control styles (both layouts
and the layout editor) come from Halo Mobile's port/web/site/style.css
(https://github.com/OMG-Guest/Halo-Mobile, CC0); the touch-mode screen, the
in-game menu and the portrait hint at the end are this port's own.
*/

/* ---------- touch controls

Laid out like the original Xbox controller (the Controller S): A, B, X and Y
as green, red, blue and yellow translucent gems in a diamond, the white and
black buttons below them, the L and R triggers above each side, back and
start between the thumbs, a round d-pad under the left thumb, and the left
stick where the left thumb lands. */
