RE: [WSG] Is it a good practice to have 'Back to Top' link?

2008-09-28 Thread Robin Shi

How about the tabs with JS? It visually breaks the page into small parts and 
switch by tabs.

Subject: [WSG] Is it a good practice to have 'Back to Top' link?

Hi all,

I have some VERY long pages in the website I maintain. Currently, I
insert 'Back to Top' after every section in the page.
Sometimes, I feel they are disturbing and am not sure if there is any
better way to do it or don't insert them at all.

Of course, splitting the page into smaller pages is the simplest way
out, but for our application, the page has to contain all the
information on the same page.

Any suggestions would be appreciated.

Cheers,
Joe

So - the visitor comes, they read to the bottom, then they have to
scroll to the top and activate the next tab (and repeat). I'm not too
keen on this idea.

Oh I did miss the point. You were talking about those small screens and the 
users really don't like scrolling. In that case, what if put the tabs on the 
bottom of the page?

RE: [WSG] Is it a good practice to have 'Back to Top' link?

2008-09-29 Thread Robin Shi

Thanks Mark for the explanation.

For those users who even don't see [Home] key or [back to top] link, I think 
they may need the extremely "good" sign to navigate inside the page.
We will be still using the tabs as navigation, but not on the top. Put the tabs 
in a div, then using the JS to position the div. If the page has been scrolled 
down or up, whatever, the JS will reposition the div to make sure it's not 
outside of the view.
But I don't like this crazy idea because
1. it increases the page-load;
2. a lot of work to do with media="print"

Cheers,

Robin

No, I think his point was that the tabs would be at the top of the page
and the user would still have to scroll back to make use of them, unless
the page was not long enough to take them out of view.

Unless you were using frames, and the tabs were outside the content frame.

Which would be a Bad Thing(tm).

Cheers

Hi Blake,

In my experience, "position: fixed" seems not work with IE.

Is it just me, or could you not use position: fixed?
