Content offset after slider loading

Hello,

On the demo (https://demo.acmethemes.com/construction-field/) and on my website (http://www.boursorama-parrainage.info), the slider is displayed with a timeshift and spaceshift after a certain number of milliseconds. As a consequence, the content after the slider is displayed first and, then, it’s moved at the bottom when the slider is fully loaded.

I would like to know if there is a way to display the slider directly (or the slider area) as I have some progressive jpeg slider images. I didn’t check it deeply but I suppose that there is a solution (fix the slider block height ? load slider CSS before ? other ?).

Thanks for your help 🙂
