A second common application of non-breaking spaces is in plain text file formats such as SGML, HTML, TeX and LaTeX, whose rendering engines are programmed to treat sequences of whitespace characters (space, newline, tab, form feed, etc.) as if they were a single character (but this behavior can be overridden).
The cellpadding attribute was added to version 2.0 of the HTML language in 1996. [4] Space between text and borders is an important element of web page design, because it improves the readability of text and visual appeal of graphics in table cells. [5]
Web browsers usually do not differentiate between single and multiple spaces in source code when displaying text, unless the text is given a "white-space" CSS attribute. Without this being set, collapsing strings of spaces to a single space allow HTML source code to be spaced in a more machine-readable way, at the expense of control over the ...
In most HTML elements, a sequence of whitespace characters is treated as a single inter-word separator, which may manifest as a single space character when rendering text in a language that normally inserts such space between words. [32] Conforming HTML renderers are required to apply a more literal treatment of whitespace within a few ...
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
The zero-width space can be used to mark word breaks in languages without visible space between words, such as Thai, Myanmar, Khmer, and Japanese. [1] In justified text, the rendering engine may add inter-character spacing, also known as letter spacing, between letters separated by a zero-width space, unlike around fixed-width spaces. [1]
This code generates "page C‑2" just like the plain code "page C-2", but prevents a line break at the hyphen. However, like , the use of ‑ instead of "-" renders the source text harder to read and edit. Don't use it unless it is really necessary to avoid a line break.
In a typewriter font, <space> will equal  , but will vary according to the font designer's specification in all other fonts, whether proportional or monospace. The HTML standard also specifies display behavior, not just character encoding, so web browsers following the HTML standard will collapse multiple <space>s to a single <space>. Non ...
