Home | Front page remains transparent

Dear Madam, Sir!

How are you?

The front page of https://1stfruit.xyz is remaining transparent- desiring white background:

1- Background was white, when the page was not yet selected to be the home page- like all the others;

2-Have entered CSS custom snippet:

.home #wrapper {
background-color: #ffffff;
border: medium none;
margin: 20px auto;
padding: 0;

Even though this is not one of your themes (as yet- but am so fond of it), and I have posted at the theme's support forum with no reply, would you maybe have experienced such a thing before and have a clue?
