Thank you David, you are very kind and helpful, and I think your recommendations worked!
I have increased the fond size a little bit more, because I prefer that.
I have another small question: Since I will be using those fonds you have recommended (Georgia + Lato), and not likely to be using others.
And have read that disabling the loading of some font groups can improve the WordPress loading speed a little bit.
Are there any fond groups / sources I can turn off from my WordPress site that safely do not include Georgia and Lato? And if yes, how could I do that?
Thank you again, very much.
