Help: Change link hover colour in post titles?

Hi guys, I’ve used WP a lot before but I just installed a new site with it, and I’m using a really cool theme I found, but one thing I don’t like and can’t seem to change is that the link hover colour on post titles does not change. I’ve looked in several places to try to find the solution and tried several times changing the code but to no avail.

My site is at: https://paulfromcanada.com/blog/, like I said I just set it up. Here’s what my style.css looks like in the area I’ve tried changing:

h1>a {
margin-left: 10px;
font-size: 1em;
font-weight: normal;
font-family: “Trebuchet MS”, sans-serif;
letter-spacing: -.1em;
}

h1 a:link, h1 a:active, h1 a:visited, a:hover {
}

According to this (https://www.tamba2.org.uk/wordpress/graphicalcss/content/index.php) there should be an “h3” somewhere in my CSS that deals with this, but all I saw was the h1 and I tried changing that but it didn’t work.

If anyone could help me out that’d be awesome…thanks!
