How can I change the name of my interests?

// Hide General.
.details-table tr:nth-child(1) td:first-child p:first-child {
    display: none;
}

// Add new title to General.
.details-table tr:nth-child(1) td:first-child::after {
    content: "New Title 1";
}

// And so on for the rest.

.details-table tr:nth-child(2) td:first-child p:first-child {
    display: none;
}

.details-table tr:nth-child(2) td:first-child::after {
    content: "New Title 2";
}
