"First word" would be like :to-content(" >") or whatever. It should be consistent with XPath, so elem::substring-before(" ") { font-size: xx-large } would be a better approach. In addition a substring-after pseudo-element could be included like elem::substring-after(" ") { color: inherit } A proposal: ----------- The ::substring-before(string) pseudo-element The substring-before pseudo-element selects the substring of the textual content of the given element that precedes the first occurrence of the string provided as argument to the selector; it selects nothing if the textual content does not contain the desired string. Example: code::substring-before("/*") selects everything before the first comment in this code fragment <pre><code> UL OL LI.red /* a=0 b=1 c=3 -> specificity = 13 */ </code></pre> The ::substring-after(string) pseudo-element The substring-after pseudo-element selects the substring of the textual content of the given element that follows the first occurrence of the string provided as argument to the selector; it selects nothing if the textual content does not contain the desired string. Example: p::substring-after("CSS")::substring-before("3") selects the string "level" in this paragraph: <p>This draft describes the selectors that are proposed for CSS level 3</p> [1] If these pseudo-elements are included in the draft, :contains pseudo-class semantic needs to be extended to process only the selected substring if called in context of one of the substring-pseudo-elements; all three pseudos need some clarification on white-space normalization as I stated earlier. See http://www.w3.org/TR/xpath#function-substring-before http://www.w3.org/TR/xpath#function-substring-after for the definition of these functions in XPath.
