Search bar disappears on small screen bootstrap css - css

Question

I bought a react template online I couldn't figure it out why this form search bar is hidden on small screen size.
<div className="col-lg-8 col-xxl-4-5col d-none d-lg-block">
<div className="header-search header-search-extended header-search-visible header-search-no-radius d-none d-lg-block">
I tried changing "d-none d-lg-block" to "d-block" but still did not work
I am not a css expert so I need a work around to make it work .
here is the full div html code:
