I list below all topic groups, which I have done according to subjects, which they handle. You can return to this topic group by using this menu and the link Table of topic groups on the top of the each page.
The font size of my pages might be too small for weak-sighted. With all browsers it is possible to zoom the font size of the main content.
In my pages is also fixed size font sizes in dynamic menus, which some browsers can zoom and some not. If the used browser can't zoom the font size it might remain too small for weak-sighted persons. Dynamic menus might be also in other respects too difficult for weak-sighted persons.
Topic group have a link to the table of contents (), which works also as the site map of the visited topic group.
Zooming the font size can commonly be found from the View drop-down menu of the browsers. It is not possible to scale fixed size fonts in MS IE for Windows browsers except creating user style sheets and setting
!important for desired element or disabling all features, which affect to font sizes (MS IE 6.0: Tools > Internet Options > Accessibility).
In Opera browsers it is possible to zoom everything. In addition it is possible to set from the preferences the smallest used font size. In new Netscape/ Mozilla and MS IE Mac browsers zooming the font size affect also to fixed size font sizes. At this mean they take better account weak-sighted persons as the most used browser.
