One of my favorite ways to change the interface is to use the split code view. If you really like working on a code, you can change the code view and see only the code. If you hate that HTML code by all means, hide it behind the design view but as I am working it is a very helpful reference to ARC as I select different elements of the page. What is happening behind the scenes?
If you are not familiar with HTML, you can actually pick up lots of HTML tags and get more familiar by just noticing what appears when you select different elements on the page. Expression Web is very well integrated so each time I select a different element on the page, it will jump to the place in the HTML code that corresponds to what you have selected on the page.
Sometimes when you are working with Expression Web, or any other web design tool that has a design interface, you will select something on the page and not always get exactly what you selected in the code. That is the bread crumb trail across the top to help make sure you really select the layer and not just the image or in this case, the link.
I can choose whether I want the image or the layer or the link selected and depending on what I want to do, for example, if I want to do apply a style, making sure I selected the right tag can be vitally important. I found the design marking if I can go back and forth between the code I see in split view and the bread crumb trail, I can get very precise and make sure I have selected the right element before I apply style, change formatting or any other change that I want to make to specific element on my page.
