I have two new blogs that i have just started on different wordpress templates. Now i am noticing if I use any html in the posts, especially div tags or if I put the more tags in the post the right sidebar is getting pushed right to the bottom of the page. If I remove the html it goes back up into the right position. I have not experienced this with any of my other blogs. i tried changing themes and the same thing keeps happening. I hope someone can help?
It's the </div> tags that are throwing your posts off. From my experience, Word Press will allow you to put HTML, and PHP into posts, but it will not let you construct a call to action within a post...it will throw off the existing code that puts the entire blog together, You may be able to do it on a page, but the sidebars are called and organized using </div> tags, if you put extra tags in there, it will throw it off. If you say that you have used </div> tags before without a problem, that would be news to me, but my advice is simple...find another way to make your function work without using </div> tags. It is obvious that it is the code that you are trying to insert, but, This is all speculation without seeing what you are talking about....the best anyone can do to help you is guess without seeing the specifics.
There is an invisible layout that controls your theme. When you place divs or tables inside posts it can knock that out. When the browser tries to load the page it realises that your content portion needs more space, so it gives it more space. It then thinks "Oh, but I've now not got enough space for the part on the right" ... so it chucks it to the end. The divs will be causing the problems. They need to be set narrower. The problem for people without knowledge/skills/tools is you can't see the invisible placeholders that are determining where the page fits to easily be able to fiddle with it.
have you tried it in multiple browsers? i know IE is a pain in the ass for doing stuff like that. usually its a CSS related problem
