Visual editor and HTML coding

I am using the visual editor plugin (from site-builder). It says that it supports HTML. However, when I type HTML into the box and then ‘update’ it will just show the coding I have used on the main web page.

The main reason why I have this problem is:

1. If I am trying to align a simple text widget, it ends up aligning with the whole page and pushes out all the writing that I had next to it.
2. Visual editor doesn’t seem to have a way to change the look of HTML links. They are always blue/underlined and I cannot seem to use CSS to remove that effect without the language showing up on the actual page.
3. If I just use Vantage Headline (which recognizes HTML and aligns itself automatically), there is still an empty space above the text.

Basically I want the pictures (at this point I am using singing success for a place holder) to be closer to the words underneath them. The font/look and alignment of the words is just how I want it. I achieved this by writing HTML into Vantage Headline. Surely there’s a better way to do this? I’m surprised I can’t just write HTML/CSS into visual editor and for it to recognize that.
