bootstrap-4

问题 For a website I need one horizontal menu in Bootstrap 4 (.container) after the header (.container-fluid) which should collapse into right sidebar using slideout.js. Currently I have horizontal menu (code below) but I can't figure out how to properly collapse items for slideout. How can I do it? I can't load two menus. If there is any solution I am open to suggestions. <nav class="navbar navbar-expand-md navbar-light bg-light m-0 p-0" id="menu"> <div class="container"> <div class="collapse

问题 I want to create a responsive grid of squares with Bootstrap 4, to do so, I'm doing something like this (One row): <div class="container"> <div class="row"> <div class="col"></div> <div class="col"></div> <div class="col"></div> <div class="col"></div> <div class="col"></div> </div> </div> And I'm setting the col class to have the following rule: .col { padding-top: 100%; } But that only creates a row with each column of the height of the viewport.

问题 I've got a website being developed with Bootstrap 4. When viewing from a mobile device and the menu items have collapsed to the 3 bars, the menu items are not clickable. I've tried implementing it the way the bootstrap docs suggest, but it's still not working. I've tried some other tweaks to no avail. What am I doing wrong here (other than using the alpha version)?

问题 according to the bs3 to bs4 migration docs: Buttons Renamed .btn-default to .btn-secondary. But the secondary does not look at all as the old default button. I mean the white shaded button/dropdown etc... When I do btn-light that is not the original btn-default. So how do I get my default theme back for buttons/dropdowns etc... ? AFAIR literally now... there was a correct default button in the bs4 but it was in a former alpha version. I guess thats true. 回答1: The btn-outline-secondary class
