Trying to add a widget but facing issue on mobile

Hello GP Team,

I am attempting to add a widget to a page that David helped me fine-tune GP in a previous post. However, I am encountering an issue where something appears to be off on mobile, but I am unable to determine the cause.

I have also included the link to the page in question. I would greatly appreciate your assistance.

Thank you.

PS: Here's the code David made that I inserted into my style.css.

body[class*="docs"] #content {
flex-wrap: wrap;
}

body[class*="docs"] #content > div {
width: 100%;
}

@media(min-width: 769px) {
.docs-wraper {
display: flex;
}

.docs-single-templates-enabled #secondary.docs-sidebar-area {
width: 24% !important;
}
