1. Tips, Tricks and Troubleshooting
1. CSS Styling
To set the background color of an HTML element, use one of the following methods:
CSSStyleDeclaration style = ((ElementCSSInlineStyle) element).getStyle();
style.setProperty("backgroundColor", "red", null);
((CSS2Properties) style).setBackgroundColor("red");
HTMLUtils.getStyle(element).setBackgroundColor("red");

Only use if the style property is not known at compile time. Hence, the
above usage in is discouraged.
Note: It is good practice to use CSS style sheets, possibly in conjunction with HTML class names, instead of setting style properties directly on individual elements.
1. Attribute removal
To remove a style attribute, set it to the empty string, not to null.
CSS2Properties style = HTMLUtils.getStyle(element);
style.setBorderTop("solid black");
// Later ...
style.setBorderTop("");

2. URL Query Parameters
If the onLoad-method has a java.lang.String[] argument,
then the values of the URL query parameters are passed through this argument.
The java.lang.System.getProperty(String key) method can also be used to access
URL query parameters.
3. Trouble Shooting
1. Loaded page is dead
Is the correct assembly included within the <script/> tag? Is the correct static method specified as onLoad handler?
