Of course we could do that, but I thought it's more comfortable to have
"speaking ids" while debugging the CSS files.
Maybe this can be useful for other things too.
But you are right: In the first place the id has to be just unique.
Everything else is nice to have but not a must.

>> <div class="myextension_whatever_imagecontainer"
>> id="myextension_whatever_789_1_4">
>> <div class="single_imagecontainer" id="tt_content_125_2_5">
>> <div class="single_imagecontainer" id="tt_content_123_1_6">

Well - it would be nice to get something like this from stdWrap so that an
admin could assign additional dynamic CSS values to other content elements
too.
For extension developers this would mean they have to use the same stdWrap
function to assign their values. Just to make things as compatible as
possible.

Something like

temp.whatever = COA
temp.whatever {
    stdWrap.dynamicCSS_entry = 1
    stdWrap.dynamicCSS_entry {
        tag = <div>
        baseClass = imagecontainer
        params.cObject = COA
        params.cObject {
            text-align = TEXT
            text-align.field = fieldname
            width = TEXT
            width.data = whatever
            width.wrap = |px
        }
    }

This would generate an output like

<div class="imagecontainer" id ="asdf87699876asdf2">
    #Rest of the COA including wrap, innerWrap, outerWrap etc.
</div>

and the appropriate style in the CSS file

#asdf87699876asdf2 {
            text-align = left;
            width = 128px;
}

Of course you wouldn't have to use cObject for the params when you are using
the function inside your own PHP stuff.
Simply populate an array and you're done.

What do you think?
