问题 I have almost got a nested Bootstrap menu working exactly as I want it. The menu is on two levels. The top are major menu categories, the bottom sub-categories. Selecting a major menu will turn that menu heading active and open up the appropriate sub-category, with no subcategory selected at this time.

问题 In R Shiny, I would like to change the background colour of the navbar menu. I would like to change the colour everywhere on the menu bar (including the colour of the buttons when hovering over them, or when they're inactive, etc.), except for the font, to one colour (black). However, I do not wish to change any other default colours, such as the background colour of the main part of the page. I've attempted to do so by creating a CSS file as follows: body, #selector, .container, .navbar

问题 My fixed navbar works fine when I resize my computer screen to below 980px. Once my screen is 979px or less the navbar collapse kicks in and works perfectly. However, when I push code up to Heroku and load the site on my iPhone 4S, not only does my navbar not collapse, but it looks a bit different -- the float right drops underneath the logo causing it to look weird. Here is my custom.css.scss file: @import "bootstrap"; @import "bootstrap-responsive"; /* universal */ html { overflow-y: scroll
