How to add css in post?
I use Wordpress. I need to add in my post CSS and I didn`t find any plugins...
Have you tried inline style="background: #00ff00;"?
Or am I not understanding your questions correctly? You should be able to do inline styles by clicking the HTML tab when you create your post.
As I was feeling generous, I did a search for 'wordpress css in post' and got this result: http://digwp.com/2010/02/custom-css-per-post/
Hope that helps.
