css

问题 I am running a development server and I'm trying to load some static pages and files (images, css and javasripts) in my rails application for testing. (In general, I'm new in rails.

问题 I've tried to create this css shape (ribbon) using border radius but I'm unable to do so, the curve I'm able to get isn't exactly matching the div's curve in the image. background: #008712; width: 89px; height: 22px; box-shadow: #d0dae0; background-color: #008712; border-bottom-left-radius: 70px; } If I get this curve right that solves the problem, I would like avoid svgs if possible. 回答1: Use pseudo element with some skew transformation: .box { width:200px; padding:8px; font-size:25px; color
