Prevent Custom CSS Affecting Table of Content Plugin?

Hi, I'm using the following custom CSS to make all text links bold and underlined. But I want to exclude this from affecting the links in the Table of Contents plugin. Is there a way to prevent this? Thanks Site = makemesustainable.com

/* Link Float Down */
.entry-content p a:hover,
.entry-content li a:hover {
border-bottom: 2px solid currentcolor;
}
.entry-content p a,
.entry-content li a {
border-bottom: 2px solid currentcolor;
}

/* Bold Links */
.single-post .inside-article .entry-content p a,
.single-post .inside-article .entry-content li a {
font-weight: bold;
}
