I’ve just published a NetBeans 8 plugin that allows developers to quickly add links to Bootstrap CSS (hosted by bootstrapcdn.com) into their .xhtml files.
Once installed, the plugin is appears on the “Insert Code…” dialog within .xhtml files.
Selecting the “Bootstrap CDN…” option causes the Bootstrap version selector dialog to be displayed.
Select a version of Boostrap CSS to be linked to and press the “OK” button and a link will be added into the file, e.g.
<link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet"></link>
Let me know if you find this useful or if you find any bugs in the plugin.
