Hallo,
9.3.3 Hyphenation
In HTML, there are two types of hyphens: the plain hyphen and the soft hyphen. The plain hyphen should be interpreted by a user agent as just another character. The soft hyphen tells the user agent where a line break can occur.
Those browsers that interpret soft hyphens must observe the following semantics: If a line is broken at a soft hyphen, a hyphen character must be displayed at the end of the first line. If a line is not broken at a soft hyphen, the user agent must not display a hyphen character. For operations such as searching and sorting, the soft hyphen should always be ignored.
In HTML, the plain hyphen is represented by the "-" character (- or -). The soft hyphen is represented by the character entity reference ( or )
In deinem Browser vielleicht... aber wenn das in einem anderen Medium dargestellt wird, kann es viel besser zusammen präsentiert werden (zum Beispiel Sprach-Browser benutzen das).
In http://www.w3.org/TR/REC-CSS2/selector.html steht, dass
input[type="text"] { border-widht:3px; }
funktionieren sollte. Ob die Browser das können, weiß ich nicht, habs noch nie benutzt.
