CSS

.chip {
    /* Center the content */
    align-items: center;
    display: inline-flex;
    justify-content: center;

    /* Background color */
    background-color: #d1d5db;

    /* Rounded border */
    border-radius: 9999px;

    /* Spacing */
    padding: 0.25rem 0.5rem;
}

.chip__content {
    margin-right: 0.25rem;
}

The close button is used to create a button for removing the chip:

.chip__button {
    /* Reset */
    background-color: transparent;
    border-color: transparent;

    /* Cursor */
    cursor: pointer;

    /* Size */
    height: 1rem;
    width: 1rem;

    /* Used to position the inner */
    position: relative;
}

.chip__button-line {
    /* Background color */
    background-color: #9ca3af;

    /* Position */
    position: absolute;

    /* Size */
    height: 1px;
    width: 100%;
}

.chip__button-line--first {
    /* Position */
    left: 0px;
    top: 50%;
    transform: translate(0%, -50%) rotate(45deg);

    /* Size */
    height: 1px;
    width: 100%;
}

.chip__button-line--second {
    /* Position */
    left: 50%;
    top: 0px;
    transform: translate(-50%, 0%) rotate(45deg);

    /* Size */
    height: 100%;
    width: 1px;
}
