orschiro You can add a signature message that appears automatically below all your comments
Use this CSS code in your custom CSS:
.CommentPost .Post-body::after {
content: "This is a signature area. It appears below all comments.";
display: block;
margin-top: 10px;
padding: 10px;
background-color: var(--control-bg-shaded);
border-top: 1px solid var(--muted-color);
font-size: 0.9em;
color: var(--text-color);
text-shadow: 0 0 0 rgba(0, 0, 0, 0.2);
}
You can customize the colors, but in its current form, the design will work seamlessly with both light and dark modes. Additionally, you won't need to use a signature extension after adding this.
