Can't override theme style with CSS

Technical Q&A

I cannot for the life of me get my css to change a font size—it will change the font, but not the size.

My store preview is available here.

The text I would like to change is the static text overlaying the hero image. [note the image also has text within it, to be replaced once I get this problem figured out]

Here’s the css I am using:

/* This is the MORE GOODNESS title font, top of homepage */
.block-id--template--15051013783622__af3e824e-6ca9-4ac4-9510-a07cb14e4a66-text_static-1 * { 
  font-family: "sirenia", sans-serif; /* this line works */
  font-weight: 900;
  font-style: italic;
  letter-spacing: 0;
  font-size: 200px !important;  /* this line DOES NOT WORK */
}
/* This is the MORE GOODNESS subtext, top of homepage*/
.block-id--template--15051013783622__af3e824e-6ca9-4ac4-9510-a07cb14e4a66-text_static-2 * { 
  font-family: freight-neo-pro, sans-serif; /* this line works */
  font-weight: 600;
  font-style: normal;
  letter-spacing: 0;
  font-size: 40px !important;  /* this line DOES NOT WORK */
}
