at work they decided to center divs thus:
body {text-align:center}
#content {width: 612px; text-align:left; margin: 0 auto 0 auto; }
this works fine in IE & FF, EXCEPT in FF it doesn't work if I change
'auto' to 0 for left and right margin values; I have to leave those at
'auto'.. so I would like to know what exactly means 'auto' -- what
value it represents exactly (and does it apply for all elements/values
you might apply 'auto' to?)
(please don't tell me I should do this differently, I don't think they
will change the template at this point.. I had not say in it.. I just
would like to know what I can expect from 'auto' value..)
thank you very much..

It doesn't represent a value exactly. It means that you are leaving it
to the browser to figure out the best value. Of margin-left,
border-left, padding-left, width, padding-right, border-right, and
margin-right, if you specify measures for some and auto for the others,
the browser works out the autos as it thinks most suitable.

This could be summarised as:
margin: auto;

That would be margin: auto auto auto auto, not margin: 0 auto 0
auto--unless auto necessarily resolves to 0 for vertical margins. Does it?
In any event, it could definitely be abbreviated to margin: 0 auto.

I know this is a strange question, but I have inherited a system where files are copied

the number can go without the system crashing.
An ancillary question is how one resets an auto number so that the sequence starts again
at 1.
In the case of this file, the auto number field serves no useful purpose except as an

I have 2 virtually identical tables and wish to move data between them.
Basically one table is called "live_table" and the other is named

primary key is just a standard integer.
Here's the life-cycle:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
