How to use alignment in Microsoft word
Alignment shows where texts appear on each line in relation to your document margins.
In word, there are four types of alignments:
Left: this aligns texts in straight left margin
Right: this aligns texts in a straight right margin
Centre: this aligns the texts at the center of your document.
Justified: this aligns you text on both sides of your document (left and right).
It all depends on what you want, most often; users prefer the justified texts because it looks much presentable.
