Off-Grid Blocks

[Sokair]

So then I'm working on my "fun" map..but then sometimes blocks, rooms, or anything I include in my map gets "off-grid". It doesn't snap, or align to the grid. This really frustrates me, how do I refrain this from happening?
EDIT: Is this supposed to happen? I'm all new to Source SDK.

You're probably pressing shift-w, which disables snap-to-grid, or lowering the grid down to 1 by accident. In the lower right of your screen, Hammer should tell you if grid is on or off, and the grid size. To turn snap-to-grid on and off, press shift-w; to increase/decrease grid size, press ]/[, respectively.

Thanks so much. I'm probably confused, pressing random buttons. Thanks (again)!
