Here's a good drop-in solution for perfectly centered circular X icon buttons

• Using only CSS
• Not relying on a font
• The thickness and length of the tines of the X can be configured without affecting centering, using width and height in the pseudo element rule .close::before, .close::after
• Screen reader support using aria-label
• Works on a light or dark background by using transparent grays and currentColor to adapt to the current text color specified on the button or an ancestor.

.close {
    vertical-align: middle;
    border: none;
    color: inherit;
    border-radius: 50%;
    background: transparent;
    position: relative;
    width: 32px;
    height: 32px;
    opacity: 0.6;
}
.close:focus,
.close:hover {
    opacity: 1;
    background: rgba(128, 128, 128, 0.5);
}
.close:active {
    background: rgba(128, 128, 128, 0.9);
}
/* tines of the X */
.close::before,
.close::after {
    content: " ";
    position: absolute;
    top: 50%;
    left: 50%;
    height: 20px;
    width: 4px;
    background-color: currentColor;
}
.close::before {
    transform: translate(-50%, -50%) rotate(45deg);
}
.close::after {
    transform: translate(-50%, -50%) rotate(-45deg);
}
