Theme Horse

Hi ujjal.subscription.ghosal,
We don’t have this feature. We have designed our theme this way. It needs code customisation. So you need to hire a developer to fix the issue.
3. How could I set a slogan on top of the header image (like the demo of the theme)?
=> This is not below the header image, the slogan is above the slider. You may use the slider in place of header image it you want. just follow the theme instruction how to add slider.
4. Is there any option to change the font of the Slogan? If not would the Pro version have that option? Same question regarding colour as well
==> yes we have the slogan options to change the font size and we also have the font options and also the color options.
Thank You!
