how does a hiatal hernia cause gerd?

"Yo-Yo" stomach.: One mechanism that prevents reflux of food or acid from the stomach up the esophagus is the fact that the pressure within the abdominal cavity is higher than the pressure in the stomach. If the stomach "yo-yo's" into the chest cavity through a hiatal hernia, the negative pressure within the chest cavity changes this pressure gradient, favoring reflux.
Dr. Scott Grover

Mechanics: The hiatus helps control reflux by placing pressure at the distal esophagus where it comes through the hiatus. When you have a hernia, this pressure is reduced which can now allow reflux to occur. The position can change with a hernia and this change of position can allow reflux as well.

A 23-year-old female asked:

If I eat something that bothers my GERD in moderation, will it make my hiatal hernia bigger?

Not necessarily: The hiatal hernia would be made worse by increasing your intraabdominal pressure--from activities like heavy lifting. Things that bother GERD increase the reflux of stomach contents into the esophagus. The two are not necessarily related.

It's up to you: There are no hard and fast rules. Eating something that gives you symptoms of gerd is your choice. If you want to avoid the symotoms then don't eat it. It certainly will not affect your hiatal hernia size.
