# <apex:slds/> tag vs the Lightning Design System Static Resource for Manage package developement

I am new to manage package development. I want to develop a Visual force page with Lightning styles. I know the two approaches as below:

1. Using <apex:slds> tag. (I will have to change the version if the VF page to 39 or above)

I am a bit concern about the changing version for manage package component. Also, does referring <apex:slds> tag would create any ambiguity in long run in case any style class changes? As referring static resource I can rely on the resource CSS I uploaded. Apart from this, I am missing on any perspective or alternative doing the same?

Any suggestions will be helpful! Thanks!

• AFAIK you don't need any of them, slds is generally available, OOTB, just use slds classes in your markup, and should be working fiine – patryk Dec 18 '18 at 7:41

You should use apex:slds in all cases.
