Alignment
What is alignment in design?
Alignment is lining elements up to shared edges and a common grid, so the eye reads invisible straight lines connecting them. It is the cheapest way to make a layout feel considered - and its absence is the first thing that reads as amateur.
Also known as: visual alignment, edge alignment
The demo
The same little profile card, two ways. Flip between ragged and aligned and notice the tidiness arrive before you can point to what changed.

Switch to aligned and watch the layout settle.
What this demo shows (text version)
A profile card with a name, a role, two lines of detail and a message button. In ragged mode each of these sits at a slightly different left indent, so there is no shared edge for the eye to follow and the card looks subtly messy.
In aligned mode every element snaps to the same left edge, marked by a faint guide line, so they all share one vertical line. The content is identical in both modes; only the left edges change. The aligned version reads as tidier and more deliberate, which is the whole effect of alignment - it creates invisible lines that make a layout feel ordered.
The ragged version felt vaguely untidy long before you could say why; switch on alignment and the same elements suddenly look deliberate, calm, trustworthy. Nothing moved but a few pixels of edge. That quiet sense of order is alignment doing its job below conscious notice.
The rule that fixes most layouts: every element should line up with something else on the page. Pick a small number of shared edges and snap to them; strong left alignment usually beats centring for blocks of text, because a hard left edge gives the eye a consistent line to return to. Stray, almost-aligned elements are worse than boldly different ones - the near-miss reads as a mistake.
Alignment is invisible when right and glaring when wrong, which is why it rewards a grid. A grid is just a set of agreed lines so that everything has a shared edge to meet; it turns "does this look off?" from a judgement call into a yes-or-no. Pair it with consistent spacing and most of "looking designed" is already done.
