Change loading animation

[ildarius]

Hello

I was wondering if there was an easy way to change the loading animation in the screenshot below to a loading bar instead of the wheel that turns? Maybe there's a parameter that can be switched somewhere? Or may be an animated GIF file? (pardon my ignorance)

Sorry I don't have much details about the version etc. It's a theme that came with the swiper-bundle.min.js which seems to be loading the animation when the page loads.

Thank you
