content:"\e61e" is in the
.icon-trash:before class' CSS. I know that they use a font to make icons but I don't know what "\e61e" is? Any explanation?
Thank you in advance.

But as Joonas mentioned in the comments, a font can map a character like this to a symbol, in this case an icon, of their choosing. So in actuality, what you're seeing is likely different than this character - likely a trash can icon.
Since it's inside of a
::before (two colons are used because it's a pseudo element - one colon should be used for pseudo-classes), that allows it to be placed separately from the
.icon-trash element itself, usually before or after the element. This is very common for icon fonts to do.
