Small alignment and adjustments for Slider Revolution Slides

I need to make some adjustments on a Homepage slider for Revolution slider. At the moment some text is unaligned on different devices and heights. I need to standardize so the size of the headers that look good on all devices and heights.

• Homepage Slider had 3 slides
• 2 Languages (French + English), so 6 slides total
• The only thing I need is for the text to align centered and sizes of text to be all standardized on each slide.
