I need exactly the same effect as shown in the example.

A photo of the trainer on the front, and on the back, information about him. Preferably in CSS. Is this possible with wysiwygwebbuilder?
And if not, is it possible to import things from CodePen into the builder so that it works?

You can use the following to add import custom/external code HTML Object Please note there is no help on how to use as it is understood you will understand to to add this yourself.

There is no need to write code for this.
You can implement this with a rollover layer and cards.
