I'm designing a Neocities site and on one of my pages the background image isn't showing up. I've tried doing it in HTML and CSS but neither will work.

Use this code

.square {
text-align: center;
background-color: #16a868;
line-height: 70px;
width: 400px;
height: 800px;
color: #701ba1;
margin: 20px auto;
background-image: url(https://www.imgonline.com.ua/examples/two-tone-blurred-background-1-big.jpg);

}
