 Hi Prateek,
   Salesforce Lightning Design System (SLDS) is a CSS based framework. SLDS provide styling to give more look and feel of lightning.

   Certain benefits of using Salesforce Lightning Design System:
    -By using SLDS it’s easier to build apps which are responsive and also have the look and feel similar to Lightning Experience.
    -It is compatible with multiple browsers like  Google Chrome, Latest Mozilla Firefox,   Latest  Safari Latest Internet Explorer 11 and above.
    -It provides a robust grid system because of which It is easier to build responsive layouts that work elegantly across different screen sizes.
    -The CSS is fully namespace with the slds-prefix to avoid CSS conflicts.

Nowadays you can use lightningStylesheets for styling your VF pages. https://sfdcpanther.wordpress.com/2017/10/16/automatic-style-your-vf-into-lightning-experience-lightningstylesheets/
