Use a Custom Stylesheet in a Visualforce Email Template
By default, Visualforce email templates always use the standard look and feel of
other Salesforce components. However, you can extend or overwrite these styles by defining
your own stylesheet.
Unlike other Visualforce pages, Visualforce email templates cannot use referenced page styles or static resources. Although the CSS appears to render in the email template preview pane, it does not appear the same to the recipients of your email. You must define your style using CSS within <style> tags.
This example changes the font of your email to Courier, adds a border to the table, and
changes the color of the table
rows.
<messaging:emailTemplate recipientType="Contact"
relatedToType="Account"
subject="Case report for Account: {!relatedTo.name}"
replyTo="support@acme.com">
<messaging:htmlEmailBody>
<html>
<head>
<style type="text/css">
body {font-family: Courier; size: 12pt;}
table {
border-width: 5px;
border-spacing: 5px;
border-style: dashed;
border-color: #FF0000;
background-color: #FFFFFF;
}
td {
border-width: 1px;
padding: 4px;
border-style: solid;
border-color: #000000;
background-color: #FFEECC;
}
th {
color: #000000;
border-width: 1px ;
padding: 4px ;
border-style: solid ;
border-color: #000000;
background-color: #FFFFF0;
}
</style>
</head>
<body>
<p>Dear {!recipient.name},</p>
<table border="0" >
<tr>
<th>Case Number</th><th>Origin</th>
<th>Creator Email</th><th>Status</th>
</tr>
<apex:repeat var="cx" value="{!relatedTo.Cases}">
<tr>
<td>
<a href="https://MyDomain_login_URL/{!cx.id}">
{!cx.CaseNumber}
</a>
</td>
<td>{!cx.Origin}</td>
<td>{!cx.Contact.email}</td>
<td>{!cx.Status}</td>
</tr>
</apex:repeat>
</table>
</body>
</html>
</messaging:htmlEmailBody>
</messaging:emailTemplate>
Define Visualforce Stylesheets in a Custom Component
Although you cannot reference an external stylesheet in a Visualforce email template,
you can place the style definitions within a custom
component that can be referenced in other places. For example, you can
modify the previous example to place the style information in a component named
EmailStyle.
<apex:component access="global">
<head>
<style type="text/css">
body {font-family: Courier; size: 12pt;}
table {
border-width: 5px;
border-spacing: 5px;
border-style: dashed;
border-color: #FF0000;
background-color: #FFFFFF;
}
td {
border-width: 1px;
padding: 4px;
border-style: solid;
border-color: #000000;
background-color: #FFEECC;
}
th {
color: #000000;
border-width: 1px ;
padding: 4px ;
border-style: solid ;
border-color: #000000;
background-color: #FFFFF0;
}
</style>
</head>
</apex:component>
Then, in the Visualforce email template, you can reference just that
component:
<messaging:htmlEmailBody>
<html>
<c:EmailStyle />
<body>
<p>Dear {!recipient.name},</p>
...
</body>
</html>
</messaging:htmlEmailBody>
