Fix Those Jagged Edges
After banishing those extra spaces in your text and toning down the type, you now must decide the best way to line up your lines of text.
Text alignment (also known as justification) refers to how the ends of lines of text line up. Most text in books, magazines, and other reading material is lined up on the left side (in those countries where materials are primarily read from left to right). Some people also like to align the right side as well as the left. That’s called fully-justified text alignment. In desktop publishing we have rules to help you decide which alignment to use.
Use Left-Aligned or Fully-Justified Alignment Wisely
There will undoubtedly be well-meaning friends, business associates, clients, and others who will question your choices for text alignment. Be prepared to explain why you chose the alignment you did and be prepared to change it (and make necessary adjustments to keep it looking good) if the person with final approval still insists on something different.
