Only load OPC style sheet(s) at checkout

IMHO, for optimization purposes alone, the style sheet(s) for one page checkout should only be loaded when one is checking out -- else it's just extra stuff being loaded for no purpose.

What's more, when styling the OPC to use a two column layout with order details on the right, there is more tweaking to do than the wiki suggests, namely with modifying layout issues with pcMain and pcMainArea08-PC -- assuming one needs to get rid of navigation columns to make room for this.

If Instr(LCase(request.servervariables("SCRIPT_NAME")),"onepagecheckout.asp") > 0 Then      user_agent = request.servervariables("HTTP_USER_AGENT")      if Instr(ucase(user_agent),"CHROME")>0 then           %>          <link type="text/css" rel="stylesheet" href="onepagecheckout.css" />          <link type="text/css" rel="stylesheet" href="onepagecheckoutGoogle.css" />      <% else %>           <link type="text/css" rel="stylesheet" href="onepagecheckout.css" />      <% end if %> <% end if %>

IHMO, on principle alone there is no reason to include the OPC style sheet(s) except for when they are needed. This causes a lookup as well as extra CSS code (no matter how small). It's just not pro.

On the other hand, not a big deal to add the condition I mentioned, right? Why not just do it?

As for the wiki, I'll try to find a moment to do this on an OTB build and report back. In a nutshell, the issue that I've encountered is that the pcMain and pcMainArea08-PC areas in the OPC need more width than can be alloted for the rest of the site, plus the left margin that makes room for the left navigation needs to be eliminated in the OPC. As the style sheets for the OPC are called dynamically and later than other style sheets normally are, I've taken to adding them to the OPC style sheet and them dynamically including them only when they are called for as described above.

I really appreciate that you took our advise to add the order details to the right as it really is a much better layout -- esp. as I'm of the opinion that once in checkout, the most other navigation is just a distraction and should be eliminated to keep focus on this most wanted response.

I'll get back to you with more as time allows (yeah, right? I can hear the chuckling). But I'm getting more and more heat to improve load time and I'm seeing a lot of opportunity for that and hope to have something written up a week or two from now.
