7.0 - links sometimes underlined, sometimes not?

Site URL: https://www.cultivate.gg/resources

Greetings! Squarespace newb here. 👋

On one of my pages, (this one: https://www.cultivate.gg/resources) the links are underlined.

On the others (https://www.cultivate.gg/guided_meditations, or the home page, https://www.cultivate.gg), the links are not underlined.

Clearly user error, but can anyone tell me which user error ❓ And how to undo what I have done ❓

Many thanks for your time and attention. 😊

/* Add this code to Design -> Custom CSS */

#content a {
	text-decoration: underline;
}

@ShaDubya this will take care of adding the underline to all your links
