JSTL Loop

<c:forEach begin="0" end="${numbers}"   var="status">
 ${status}
<c:if test="${status %2 == 0}">hi</c:if>
</c:forEach>

The value of varStatus represents the name of a scoped variable that you can use to obstain information about the status of the iteration performed by action.

The following code

<c:forEach begin="0" end="${pageNumbers}"   var="i" varStatus="status">
var: ${i} and status: ${status.count} <br/>
</c:forEach>

generates the following output:

var: 0 and status: 1
var: 1 and status: 2
var: 2 and status: 3
var: 3 and status: 4

<c:if test='$( param.cardType =="Visa"}'></c:if>
<c:if test='$( not empty param.cardType}'></c:if>
<c:if test='$( isRight}'></c:if>
<c:choose>
 <c:when test='${isRight}'>
  </c:when>
 <c:otherwise>
 </c:otherwise>
</c:choose>

[%@ attribute name="label" type="java.lang.String" required="true" %]
[%@ attribute name="compulsory" type="java.lang.Boolean" required="true" %]

CSS

Writing about web page http://www.w3schools.com/css/css_syntax.asp

This is the only CSS acknowledge I need to know :)

Selectors: Any HTML element is a possible CSS1 selector
Contextual Selectors: P EM { }
Class selector : selectors.class i.e., p.right. the classes can be combined e.g class="classA, classB"
ID selector : element.id i.e., p#right
Without the prefix selector, it will allow to any element
Contextual ID/Class : #form_properties table ??
Inherentence:
span.highlight {background–color–yellow} will only applied to span tags with a declard class attribute of hightlight.

Table Element Display

In first column, you have a checkbox. In second column, you input some text. Then the text will align to left and close to checkbox.
If you have a text or textarea field and use colspan="2". It will force checkbox column become very big and consequently the text become very far to checkbox.

I fix this by use a text style. td width: 20
