问题 Despite it compiles and runs in sbt console. Intellij complains that I should have Binding[Node] instead of Elem in editor. @dom def renderDiv: Binding[Div] = <div>...</div> From intellij IDEA's perspective, this method returns a Elem which is a subtype of scala.xml.Node , but when rendering: dom.render(document.getElementById("root"),renderDiv) it requires a org.scalajs.dom.raw.Node .

How can the tight bounding box be selected for a rotated text as shown in the image below. (The text was

问题 i'm pretty new to modern frontend development tools. I installed Nodejs and NPM. Downloaded some packages (es: "jquery") and everything worked.

问题 I am writing a front-end code for a website using jQuery and AJAX and Handlebars.js. I have HTML,CSS and script.js files. I am pretty new to Javascript and techniques. This is the first time i'm using Handlebars in my code. I used JSON parsing to parse through the entire data provided in a URL. It's something like {"products": [{"id": 0, "name": "Ocean Blue Shirt", "description": "<p>Ocean blue cotton shirt with a narrow collar and buttons down the front and long sleeves.

问题 Is there a plugin/download for Velocity syntax in WebStorm? I came across this post but do not have the dir filetypes in my path (for Mac). I'd like some syntax highlighting for easier reading if it's available: 回答1: Velocity support in only available IntellJ IDEA Ultimate.
