Should delete button be on left or right?
Update: For the positioning of the buttons, I am following Luke Wroblewski's recommendations from eye tracking research for web forms (basically, the best positioning is to have the actions aligned left with the primary action on the left).
Where should back button be placed?
Place a persistent Back to Top button in the lower right side of the page. This is where people expect to see it. This position is out of the way, but noticeable. When the button is placed in a different place on the screen, it is often ignored.
What is the best color for delete button?
Used correctly, it can prevent the user from doing something dangerous which cannot be reverted. When designers use red for delete buttons, the color naturally gives users pause due to its connotations. Both deletion of a file or closing an account are good examples of using red in design.
