Block of text
A block of text is text that is grouped together in some way, such as with the use of paragraphs or blockquotes on a Web page. Often times, the text takes on the shape of a square or rectangular "block". For example, the paragraph below is a block of text.
This paragraph forms
a block of text, which
can be short like this,
or extremely long!
When reading Web content, users tend to like text broken up into shorter "blocks" that have a clear separation between them (such as the use of paragraphs). For example, the blocks of text below should be fairly easy to read and to locate where lines and ideas begin and end.
This block of text is the first paragraph in this
example, and is not very long.
This block of text is the second paragraph, and
is also not very long, which is nice.
On the other hand, if the content within a block of text is long and has no visual separation, it is much more difficult to read, as shown in the example below.
As you can see, the previous block of text was probably a bit more difficult to read. It ran a bunch of topics together into one block, rather than separating them with paragraphs or through other means (sidebars, tables, etc). If this were to be posted on an Internet forum or blog others might comment "Please use paragraphs" or "I stopped reading because it was such a long block of text". Typically, it is best to separate text into shorter, more manageable blocks.
When blocks of text are referred to in Web page coding, it is often in reference to how they are marked up, formatted, or controlled via scripting/programming. For example, a Web developer may want one text block formatted in bold and another in italics. Or, he or she may want a block of text to display only when a visitor performs an action on the page, such as clicking a button.
