I was going thru Trailhead module in SDLS.
There it is mentioned
<html xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" lang="en">
Can someone tell what is the use of this tag. Bcoz even if I remove this from code ,still the output is same.
My code from trailhead :-
Salesforce Lightning Design System Trailhead Module
<!-- MASTHEAD --> <p class="slds-text-heading--label slds-m-bottom--small"> Salesforce Lightning Design System Trailhead Module </p>
Even the code written in tag also doesnt create any difference . ExcePt the tag ,which is required to include slds. IF it doesnt create any difference then why to use it ?
