For the button graphics, I have no solution, perhaps later
Put your image in the Resource and this code in CSS, you can play with the values and top, bottom, center etc.
To get it (global) to work with the desired results I had to cut & paste and then modify a bunch of stuff from the CSS. Then RW crashed so I had to do it over again - o well
If you are copying from this message, make sure you paste it in the global css area using Edot -> Paste as plain text so that no formatting is retained and causes problems. You can also afterwards, select the CSS and go to File -> Ignore formatting…
Also, the your_image.jpg must be in the root of the Resources area or if you add them to a sub-folder in Resources then you have to add that to the path in the css.
If you put it globally, you have it in all sides equal. Works for me without problems!
You can still have other menus on certain pages. Look page 3 in demo.
I tested everything with me, works very well. Look here!
There is an additional code, now it’s perfect. I put it to the other codes, in global CSS.
