C What conceptual schemes and term trees relate with CSS

Handled conceptual schemes and term trees


Conceptual shemes

HTML/XML comment tag

comment tag
open identifier end identifier
markup open delimiter comment open delimiter comment close delimiter markup close delimiter
<! -- comment text -- >

Element tags

start-tag end-tag
open delimiter generic identifier close delimiter open delimiter generic identifier close delimiter
< HTML > contents </ HTML >

Term trees


CSS needs identifiers in two meanings. First the browser must find target elements to the declaration-blocks. The browser needs element and rule identifiers in the relation to the main documents. These could be called as external identifiers. Second CSS needs internal identifiers in order that the CSS-parser could be able to read correctly individual style sheets. It must be able to identify properties. The browser needs internal rule and property identifiers. I have completed the term list also with terms, which are not handled in the actual explanation page of the used terms.

Markup codes

In addition the same kind of tags as xml-declarations are used also in server-side scripts, for example in PHP3 (<?php ... ?>; ASP and many other server-side scripts use instead <% ... %>).
