Edit image alignment in WordPress twentysixteen child theme on attachment page [closed]

Add these 2 lines to your css file in your child theme. You can change the percentages to suit your needs. (I’ve provided a starting point of what I think looks pretty good)

//text size
.entry-footer {
    width: 30% !important;
}
//picture size
.entry-content {
    margin-left: 55% !important;
    width: 30%!important;
}
