  • Inline css code can be defined for HTML tags inside the HTML page.
<apex:page standardController="Account">

<style>

html,body,p {font-family:sans-serif;}

</style>

<apex:form>

<h1> {!Account.Name}</h1><br/>

<h2>Account Details</h2><br/>

<div id="theAccForm">

<div>

<apex:outputLabel for="name" value="Account Name"/>

<apex:inputField  id="name" value="{!Account.Name}"/>

</div> <br/>

<div>

<apex:outputLabel for="emp" value="Number Of Employees"/>

<apex:inputField  id="emp" value="{!Account.NumberOfEmployees}"/>

</div>

<div> <br/>

<apex:outputLabel for="site" value="Account Site:  "/>

<apex:inputField  id="site" value="{!Account.Site}"/>

</div>

<div>  <br/>

<apex:outputLabel for="desc" value="Description:  "/>

<apex:inputField  id="desc" value="{!Account.Description}"/>

</div>

<div id="formControl">

<apex:commandButton  action="{!Save}" value="Save"/>

</div>

</div>

</apex:form>

</apex:page>

Let’s take some examples to see how to add these to the visualforce page?

1)Adding CSS Style Sheets:

<apex:stylesheet> tage can be used to add stylesheets to a visuaforce page.

The CSS stylesheet is saved as a static resource.

The stylesheet can be referenced by the $Resource global variable in the <apex:stylesheet> tag’s value attribute.

Example: SampleSty.css


h1 {color: #f00; }

p { background-color: #eec; }

sales {color: #f60; font-weight: bold; }

Example:VisualforceExample2.vf

<apex:page showHeader="false" >

<apex:stylesheet  value="{!$Resource.SampleSty}"/>

</apex:outputText>

</apex:page>

2)Adding Javascript inside visualforce page:

  • Javascript functionality such as javaScript libraries can be accessed by including a javaScript in a visualforce page.
  • The javascript file needs to be uploaded as a static resource and called from the visualforce page.

Example: JavaSExam.js


function changeFont(input, textid) {

if(input.checked) {

document.getElementById(textid).style.fontWeight = "bold";

}

else {

document.getElementById(textid).style.fontWeight = "normal";

}

}

Example:VisualforceExample3.vf

</pre>
<apex:page>

<apex:includeScript value="{!$Resource.JavaSExam}"/>

<apex:outputPanel layout="block">

<label for="checkbox">Click this box to change text font:</label>

<input id="checkbox" type="checkbox"

onclick="changeFont(this,'{!$Component.thePanel}');"/>

</apex:outputPanel>

&nbsp;

<!-- This outputPanel is the target, and contains

text that will be changed. -->

<apex:outputPanel id="thePanel" layout="block">

Change my font weight!

</apex:outputPanel>

</apex:page>
<pre>

3)Adding iFrame Component:

  • The <apex:iFrame> component is used to create an inline frame within a visualforce page.
  • It can be used to display an external website in salesforce.
  • The external web source can be specified using the src attribute.
  • Other attributes such as width and height can be used to customize the size of the inline frame.

Example:VisualforceExample4.vf

</pre>
<!—remove the width and height attributes and see the difference à

<apex:page >

<apex:iframe src="https://mytutorialrack.com/"  width="400" height="500"/>

</apex:page>
<pre>
