Change color of heading 1

Hello,

I'm trying to change the colour of one h1 heading on one page, and none of the usual stuff is working. I'm putting it in the advanced area of that page. What am i doing wrong? At the very bottom of this page, where it says "connect with me". I want that to be red, not white https://www.caroline-shenaz-hossein.com/caroline-shenaz-hossein

div#block-yui_3_17_2_1_1579648522750_5881 h1 {
    color: red;
}

Thank you so much. I was thinking maybe the problem was that i was putting it in the wrong place. I'll research more on when the code is supported to go in the individual page coding section.
