Have been looking everywhere. Can´t find it. I know how to change
fontsizes when visiting a webpage. But I have seen also sites giving
users the opportunity to change the size by pressing one button.
example: http://www.seniorweb.nl/ ( Grote letters).
How can I code that in my webpage? No idea how it is done.
Appreciate any help

A look at the source reveals that the stylesheet is served up by a server
side process (an .asp). The link that the grote letters menu pulls down is
buried in that menu system and I couln't be bothered looking for it but I'll
bet it just sends of a parameter to the same page stating what font size is
requested. This is probably then stored in a session variable (and noticed
by the server) so an appropriate style sheet may be built, when it is
requested.

On the other hand this is a re-invented wheel, and a square one at that. The
viewer already has a perfectly servicable user setting available to change
her font size, or she would have if the site had not stupidly specified font
size in pixels, or points.

Please do not consider using this on your site. Specify font size in %,
preferably 100 of them. If you feel you should allow your viewer to change
her font size (assuming she does not know how to) then provide a link to a
page that explains how to do this for the most common browsers.

Another reason not to use that technique is that search engines will be
able to follow the link and will arrive at a page with the same content.

Search engines might think you did that one purpose in an effort to deceive
them and penalize the site.

see... http://www.google.com/webmasters/guidelines.html

"Don't create multiple pages, subdomains, or domains with substantially
duplicate content."

Search engine bots do not follow javascript generated "links".

In neither the original post or your response did I notice a reference for
javascript.

Of course I can explain how to change the size on antother page. But my
point is that the site is especially for old people. If they have
trouble reading the smaller size it would come in handy to have a button
large enough to read stating "Bigger Fonts" wich they only have to click
on and have everything on the screen larger.

Then you missed this bit in my post:

</q>

That menu system is javascript. You would have seen this if you had looked
at the source of the offending page

Seems a reasonable idea.

Go here:
http://www.hounslow.gov.uk

and look at the code (both the HTML, CSS, and JavaScript).

That'll show you exactly how to do it, and what to put on your page

Basically, they use a Javascript function to switch between stylesheets.

I was too lazy to look at the source.

I would like to avoid javascript. I don´t understand the beginning of
it. So when I just copy that I don´t understand what I´m doing.
I don´t like that

Well, Peter, what can we do? What you want to do requires some scripting.
If we don't do it that way, the best way is to simply make the text easily
resizable.

This is simply done by using either no font-size changes, or only CSS
which specifies font-size: 100% - then the standard font-size adjustments
on all browsers will be able to accomplish the font size change. Also, if
the user already has a larger font set, they'll get the content in their
set preference.

Well, it's either JavaScript or some server-side language like PHP, and
the latter would probably be more difficult to understand. Or, you could
take the advice of Richard and simply not include it. If you don't mess
with the fonts and sizes in the first place, you won't have a problem.

I had hoped there would be another solution, just to accommodate old
people with little understanding of how computers work, so they won´t
know themselves how to increase the font-size.

Peter, you could put a note on the page ("Is the text too small?") linking
to an explanation of how to change size in most browsers. It's very simple
in IE, which most of your users will be using. All users should be able to
learn this, it's only a little more complicated than the Back button.

No, I'm afraid it's either Javascript -- or a server-side solution.

If you feel it's an important facility that needs to be provided (and I
quite like the idea of giving non-computer literate folk an easy way to
adjust their viewing preferences) it's going to have to be one or the
other :-(

regards.

 

[Sam Hughes]

--even better I found it on this site :http://www.glish.com/
the possibility to change back en forth in size.
Peter

Just so you know, you have this tendency to put your replies in a manner
that makes them show up as a sig - you are putting them below a line that
consists of two hyphens and a space: "-- ". Many newsreaders show this in
a different font, or not at all, and when replying they just cut out the
sig all-together. It's confusing and weird, so please don't continue
doing that.

Thanks everybody. I know for sure that I won´t be able to do this for
my old visitors that also come to the " Digitaal Café" to learn how to
surf on the Internet. I´ll have to learn more myself to find a proper
solution.
Thanks again
