I like jquery despite its you got to know it to use it tricks and when i finally started to write some mobile friendly css i found that normal jquery is far to gone to help.
That means mobile jquery which i have spotted on the bbc and have some war stories with. Tabs are thoroughly useless, accordions work ui wise so i suppose some of gui but have not translated well into mobile phone hell.
I have a template that mostly does what i want it to do as a single template for desktop and mobile , but that might change in testing. where less ui jquery is deemed better. I expect to have at least two versions which seems an not ideal situation for a html site.
css people have this magic word where one template fits every known subset of browser and manufacturer. In practice its a huge disaster of possibly unmaintainable themes and even some examples out there do four versions of a website for devices
It strikes me that the world of css is conning itself into thinking it has no problems – very consumer driven and throw awaywhen i see something different. Data (base64) in css files further complicates life and files get minified to make them efficient or non maintainable.
