The lay out of the p-events is standard as shown in the screen below. When you want to change, for example the text color of the p-event or the font, you can do that via the page layout.
In the page layout you have the list with the HTML codes. In that list, you will find the the code .peventnameTable and .peventTable.
For example you can create more distance between the p-events and the prices or make it smaller or you can change the font. You can even change the background color.
In the picture above you will find the options .peventTable and .peventnameTable. When you have changed the settings and click on save, you will see the results immediately after clicking on save.
