[Resolved] How could I exclude the CSS for hyperlink on this place?

Hi everyone, how could I exclude this CSS styling for the “show/hide” text on Table of content? (Screenshot here)

This is the CSS code I use for my hyperlink:

/* Link hover color */
.entry-content p a {
    border-bottom: 2px solid #465362;
}
.entry-content a:hover {
     color: #333333;
}
