The solution to this problem is to employ a conditional form of pre-formatting. Because the text must be displayed just as it was typed, such lines will cause the text to spill out of the box and extent far to the right. When code lines are to be listed, it often happens that some lines are longer than the page width. ![]() To avoid a struggle in finding codes to explain the matter, interested parties can find the solution, should they ever need it, by accessing the markup for this page.īrowser Pre-wrap Test It may be of interest for some to note that, since a literal typed into an editor window displays on the page as if a conventional tag notation were entered, it follows that in order to display a literal itself on the page, such as in the table below, a still different format is needed. The literals are shown for two sets of tags in the table below. The entire tag is reconstructed by running all of the parts together into one word. Notice that literals start with an ampersand symbol then add other characters to it finally a semi-colon is added. To make a literal form, the wording within a tag need not be changed it is only the less than symbol and the greater than symbol that need be substituted. The literal form is treated as text as opposed to being interpreted as having a function. This method can be applied elsewhere, such as for the tags when similar problems arise. To get around the problem, and other problems of this type, all of the text block's pre symbols must be written in their literal form instead of their usual HTML tag format. This results since the first closing tag is taken instead of the last. When the block of text that is to be displayed within the pre tags has itself pre tags in it, then the display will be corrupted. Pre-formatted text tags cannot be used within Wiki or other lists.The tags can be styled with CSS properties.Long lines do not wrap though this has been corrected for recent browser versions.Nesting pairs of pre tags will corrupt a layout the inner pair need to be literals.It uses the whole width of the page even for a word or two, unless the tags are in-line styled.The format looks contrived in that it does not entirely match any page format.They are simple to use as such, their shortcomings are easily dismissed.However, a number of HTML-like tags have been made for other kinds of pre-formatted text these preserve white-space to varying extents and each has characteristics of its own. ![]() True pre-formatted text is said to preserve white-space, because it must display text exactly as it is typed. As the reader will be aware, the Wiki software permits only one space after punctuation or between words, and will ignore a single line space, needing two of these to make a new paragraph. Un-formatted text also depends on the software to handle line spacing, and to remove any extra spaces between words. It is distinguished from the more usual un-formatted text, where the software takes care of wrapping text while the user just keeps typing. It is seen mainly in writing for poetry, prose, lyrics, and most of all, in the listing of programming code. It has spacing in it that is contrary to the preferred web-page layout, usually because its format has been determined in the culture from which it was obtained. Pre-formatted text is text that has been wrapped and additionally spaced by the user. ![]() 3 The 'code' and 'syntaxhighlight' Tags.
