The 2012 theme for WordPress is a fully responsive theme that looks great on any device. Features include a front page template with its own widgets, an optional display font, styling for post formats on both index and single views, and an optional no-sidebar page template. Make it yours with a custom menu, header image, and background.
Although I find Twenty Twelve easy to use I don’t find it very responsive. Every time I click on a new page in my navigation bar blue links very briefly show behind each page which is not good. My site is at http://www.fatlossfactorreviews.co.uk and you can see what I mean when you click on each page link in the nav bar.
Keep it simple ! Wonderful : clean and mean! So far, no frustrating experience, a pleasure to work with. The problem of the box-shadow around images in pages and posts was easily solved by reading the community discussion about it. Great Theme!
I think people considering using Twenty Twelve should be aware of a serious compatibility issue with IE7 and IE8 – they will only display the Mobile menu. IE7 and IE8 still account for 15% of all web browser share, and IE8 will remain for a long time – there are still a lot of XP machines around.
I think Twenty Twelve’s incompatibility with IE7 and IE8 is currently a fatal flaw – it really is not okay to have the Mobile menu the only menu displayed on IE7/8. While the percentage of IE7/8 will drop, right now that means over 1 in 10 visitors will see a broken site.
Otherwise, the pure simplicity of Twenty Twelve is quite nice, and it does look like it will serve as a good parent theme – but only after the IE7/8 problem is fixed.
I was using a custom theme for my blog at first. However, after noticing a few problems with a couple of the plugins, I switched to the 2012 theme. The plugins now work great and the theme looks pretty good as well. I still need to customize the theme a bit more, but overall this theme looks pretty good right out of the box, especially if you already have a logo to use.
