CKEditor – Change the background color using JavaScript

By garywaddell ⋅ November 1, 2011 ⋅ Post a comment

I found a great article on how to change the background color of CKEditor on the fly. This became a great approach when performing form validation: Link is here, but for a quick reference, here’s how you reference it: this.document.$.childNodes[1].childNodes[1].style.backgroundColor = ‘Blue’; this refers to your CKEditor Instance (CKEDITOR.instances['instanceName'] or CKEDITOR.instances.formFieldIdName)

Opacity in CSS

By garywaddell ⋅ April 27, 2011 ⋅ Post a comment

I came across a nice article here that sums up using opacity (ie on images) that works nicely in most browsers. http://www.quirksmode.org/css/opacity.html The article summarizes it this way, use the following CSS properties to better support IE versions: .opaque { -ms-filter:”progid:DXImageTransform.Microsoft.Alpha(Opacity=50)”; // first! filter: alpha(opacity=50); // second! }

Eclipse DLTK Index Slowness

By garywaddell ⋅ March 25, 2011 ⋅ Post a comment

I have found a number of times that the DLTK index kicks off during my Eclipse Helios session and sometimes can hang. What I did to fix this was to remove the files (database index files) in this folder: <workspace folder>/.metadata/.plugins/org.eclipse.dltk.core.index.sql.h2/

Working Example using [ iframe http://www.onmiddleground.ca/index.html 640px 350], remember to remove the space before the word iframe:
