Hi I wanted to ask questions. can one adjust the editor as in Adobe DW that one can see code unteranader
Can you please explain a little more detailed what do you want to do?
If you want to have the code under the design view then you can change it in the options, the cog icon just above the profile in the bottom left. There you can change it to split vertical.
You can see the css in the Styles panel on the right.
