Note: I'm not sure about this convention. The W3C validator recognizes the "HTML Level" with or without the URL. The convention comes from mozilla (see URLs below), but Dillo doesn't have the same rendering modes, so it may be better to chose another behaviour. –Jcid

Tags

const TagInfo Tags[]

static

Function index for the open, content, and close functions for each tag.

(Alphabetically sorted for a binary search). The open and close functions are always called. They are used for style handling and HTML bug reporting. Content creation (e.g. adding new widgets or text) is done in the content function, which is not called in the display:none case. Note: many tags don't need a content function (e.g. <div>, <span>, ...).

Explanation for the 'Flags' field:

*   {"address", B8(01110), ...}
*                  |||||
*                  ||||`-- inline/block element (1/0 resp.)
*                  |||`--- inline container
*                  ||`---- block container
*                  |`----- body element
*                  `------ head element
* 

Notes:

• The upper two bits are not used yet.
• Empty elements have both inline and block container clear. (flow have both set)
