Salesforce - Static Resources

The user interface in a Visualforce base can display dynamic content the value of which keeps changing based on user responses. But there are times when we need some content which should not change with the change in values of other components in the page. For example, an image file may be required to remain constant. Such content which cannot be changed in a page is known as a static resource.

Following are a few static resources in Salesforce −
