Use strong tag to make text bold

I can’t seem to get my code to bold a statement after applying the right CSS tag. Please help
Here’s the code:
~
h4 {
text-align: center;
height: 25px;
}
p {
text-align: justify;
}
.links {
text-align: left;
color: black;
}
.fullCard {
width: 245px;
border: 1px solid #ccc;
border-radius: 5px;
margin: 10px 5px;
padding: 4px;
}
.cardContent {
padding: 10px;
}
.cardText {
margin-bottom: 30px;
}
