If one follows text, it does not actually result in whitespace. But, two sequential newline sequences between text blocks results in a blank line between the blocks.

One or more space characters read by conforming display-time processors of those markup languages are collapsed to 0 or 1 space, depending on their semantic context. For example, double (or more) spaces within text are collapsed to a single space, and spaces which appear on either side of the "<code>=</code>" that separates an attribute name from its value have no effect on the interpretation of the document. Element end tags can contain trailing spaces, and empty-element tags in XML can contain spaces before the "<code>/></code>". In these languages, unnecessary whitespace increases the file size, and so may slow network transfers. On the other hand, unnecessary whitespace can also inconspicuously mark code, similar to, but less obvious than comments in code.

An XML document author can use the <code>xml:space="preserve"</code> attribute on an element to instruct the parser to discourage the downstream application from altering whitespace in that element's content. </p><p>In most <a href="/wiki/HTML_element" title="HTML element">HTML elements</a>, a sequence of whitespace characters is treated as a single <i>inter-word separator</i>, which may manifest as a single space character when rendering text in a language that normally inserts such space between words.<sup id="cite_ref-36" class="reference"><a href="#cite_note-36"><span class="cite-bracket">[</span>32<span class="cite-bracket">]</span></a></sup> Conforming HTML renderers are required to apply a more literal treatment of whitespace within a few prescribed elements, such as the <code>pre</code> tag and any element for which <a href="/wiki/Cascading_Style_Sheets" class="mw-redirect" title="Cascading Style Sheets">CSS</a> has been used to apply <code>pre</code>-like whitespace processing.
