Salesforce Ligthning Application

Hi Vikas,

Use the Lightning Design System to style your Lightning apps by extending force:slds or using a static resource. The Salesforce Lightning Design System provides a look and feel that’s consistent with Lightning Experience.

Your application automatically gets Lightning Design System styles and design tokens if it extends force:slds. This method is the easiest way to stay up to date and consistent with Lightning Design System enhancements.

Thanks
