Accesibilidad y estándares web
First of all, this is the link to the extension in Firefox Add-ons.
The extension generates an index (or map) of any web document structured with headings (in the main document, and in frames and iframes that contains), indicating the level of the headings and its possible errors. By clicking on any of its items, you can access directly to the content of the page. I think it is useful to facilitate navigation to anyone and it also is useful for webdevelopers, for consultants and for auditors:
- It shows the headings structure of the main content (first picture in this document) and of other document embedded through IFRAME element or those which are part of a series of FRAMES (FRAMESET).
- It shows all headings in the document, including those hidden with CSS techniques or those without content.
- It can warn when there are no headings in the document.
- It can warn when there are skipping level in the headings structure (second picture in this document).
- It is an index for acc_slide (or rumo_slides) and for HTML Slidy (W3C)
If the document includes frames, the panel can show differents sub-panels, one per frame, with their structure. If the document includes iframes, you can see their headings in the headings structure of the principal content, and optionally, it will show a line (or more) to see what of these are part of one document or other. You can choose this option by clicking with the secondary button of your mouse in the sidebar or in the icon in the statusbar.
If you want, you can choose and change this option (and more) through the options panel.
In the next picture, you can see the headings structure that the extension shows in the case of a document with an iframe and with incorrect skipping level (1 to 3).
And here it is a picture that shows the situation in wich there is a frameset (frames collection).
Do you think headingsMap is useful?… I’m waiting for your answer
