hi Kriti

What exactly is not working? can you please give me a little bit more details?

The effects of image constant but text moving while scrolling down

We have made the website live but these features are not working on mobile. It all looks great on laptop but on mobile the header is not sticky (it is on laptop). The parallax section on homepage dont have the same effects on mobile. Please let me know how to fix it
