I have purchased the Custom Design feature that allows me to customize my CSS. However, I am also using the Duster theme and am continuously being prompted to upgrade to Twenty Eleven.
If I do this, I am scared of how my blog will look. Will my blog be drastically affected? That is, will my CSS coding make the new theme look funny? And, is there any benefit of upgrading anyway?
The blog I need help with is barbarasbabbles.wordpress.com.
