Reply To: Not all centered wrappers center their children

Because the contents of .wrap are all in a UL with class “gallery”, and this is your CSS for that, where you specifically state text should be justified:

.gallery li {
    font-size: 1.33rem;
    text-align: justify;  /*  <--- over here! */
    padding: 10px;
    line-height: 1.5;
    margin-top: -5px;
}
