Escaping characters that break HTML
Five characters change the meaning of HTML: &, <, >, " and '. Writing them as entities tells the browser to display the character rather than treat it as markup — which is also the baseline defence against cross-site scripting when user input ends up in a page.
Numeric references (& or &) mean the same thing as named ones and work in every parser, which makes them the safer choice when the output will be consumed by something other than a browser.
Frequently asked questions
Does escaping make my page safe from XSS?
It is necessary but not sufficient. Escaping for HTML text is different from escaping inside an attribute, a URL, or a <script> block. Use the escaping that matches the context the value lands in.
Why is not a normal space?
It is U+00A0, a non-breaking space. It looks identical but prevents a line break and is not collapsed with adjacent whitespace.
