Hi there,

Thanks for contacting us. From the beginning, we try to use the bootstrap CSS framework for our product. We have recently upgraded our Helix Ultimate with some Templates. Please check our latest template.

-Thanks

If I may...

All our templates based on Helix Ultimate (it means those published in last 2 years) are based on Boostrap 4.x. The upcoming ones, after premiere of Helix Ultimate 2.0 would use Boostrap 5.x.

Jump from BT4 to BT5 would be quite easy, all major classes are very similar.

Hi thanks for your answers both of you.

My question was pretty much specific about the template business we have bought, and as far as I understand it is with bootsrap v.4 , correct ?

I would reqest to you read the previous reply. Thanks

You didn't deliver full template name and beside you can check boostrap version alone, just check /css/ folder inside template.
