One of the principles of design, alignment refers to lining up the top, bottom, sides, or middle of text or graphic elements on a page.
Horizontal alignment includes (see illustration):
- flush-left (also called left-justified or ragged right),
- flush-right (also called right-justified or ragged left),
- centered, and
- fully justified.
With vertical alignment elements can be aligned vertically — top, bottom, or middle (center), for example. Baseline alignment would be aligning text to the baseline, including adjacent columns of text.
The use of grids and guides can aid in placement and alignment of both text and graphics.
Full justification of text (fully justified alignment) can create uneven and sometimes unsightly white spaces and rivers of white space in the text. When forced justification is used, if the last line is less than 3/4 of the column width the extra space added between words or letters is especially noticeable and unattractive.
Consider using flush-left alignment. If full justification is necessary, careful attention and minute adjustments to line or column widths, changing the font size of entire document, and adjusting hyphenation can make word and character spacing more consistent.
