问题 Having a modal with id myModal I'm trying to hook up to events when it shows and closes. Following the documentation of https://v4-alpha.getbootstrap.com/components/modal/#events I have added the following to my modal component: this.modalElement = document.getElementById("myModal"); this.modalElement.addEventListener("hidden.bs.modal", this.onModalHidden); this.modalElement.addEventListener("shown.bs.modal", this.onModalShown); The event handlers for now will only console.log "shown" or

问题 I am using the Bootstrap 4 grid system , and want to float an aside down the right hand side of the screen.

I also tried containing the main content inside of a section tag, since the other two rows

问题 I am working on a template in bootstrap 4.0.0 that I will use for multiple gallery pages containing many (50+) mixed ratio images. I have a grid layout that works well except for IE11. My images are inside cards that are inside buttons and the card heights seem to be stretching to the maximum height of the responsive images.
