When step above all WooCommerce blue buttons becomes smaller.

1.1) Would want to just change ONLY “on hover” color (same your web enfold at kriesi.at).

1.2) In some of them buttons there is no effect “hover” (“Update cart” for example).

I like to add style to produce the same effect in all blue woocommerce buttons.

1.3) Which css for modify color and size button?

If I click on the logo and then go to the cart, the text is large. But it is small. How to always be small?

Thank you!

Xavier.
