Identifying the Salesforce Style Your Users See
There are two global variables that can help you identify which style a user sees: $User.UITheme and $User.UIThemeDisplayed. The difference between the two variables is that $User.UITheme returns the look and feel the user is supposed to see, while $User.UIThemeDisplayed returns the look and feel the user actually sees. For example, a user can have the preference and permissions to see the Lightning Experience look and feel, but if they’re using a browser that doesn’t support that look and feel, for example, older versions of Internet Explorer, $User.UIThemeDisplayed returns a different value.
- Theme1—Obsolete Salesforce theme
- Theme2—Salesforce Classic 2005 user interface theme
- Theme3—Salesforce Classic 2010 user interface theme
- Theme4d—Modern “Lightning Experience” Salesforce theme
- Theme4t—Salesforce mobile app theme
- Theme4u—Lightning Console theme
- PortalDefault—Salesforce Customer Portal theme
- Webstore—AppExchange theme
<apex:page standardController="Account">
<apex:variable var="newUI" value="newSkinOn"

<apex:stylesheet value="{!URLFOR($Resource.myStyles, 'newStyles.css')}" />
</apex:variable>
<apex:variable var="oldUI" value="oldSkinOn"

- Using the rendered attribute you can “toggle” which sections display.
- Since the <apex:stylesheet> tag doesn't have a rendered attribute, you’ll need to wrap it in a component that does.
<apex:page showHeader="true" tabstyle="Case">
<apex:pageMessage severity="error" rendered="{!$User.UITheme = 'Theme3' &&
$User.UIThemeDisplayed != 'Theme3'}">
We've noticed that the new look and feel is enabled for your organization.
However, you can't take advantage of its brilliance. Please check with
your administrator for possible reasons for this impediment.

<apex:ListViews type="Case" rendered="{!$User.UITheme = 'Theme3' &&
$User.UIThemeDisplayed = 'Theme3'}"/>
