Sidebar widgets are over the content in mobile mode, how can I fix it? [closed]

It’s css problem apply some css to it, you can do the following when the browser window is smaller than 800px it will hide the overflow of that div, you can simply apply it without media query as well.

add this in your style.css

@media only screen and (max-width: 800px) {
div#box {
    overflow: hidden;
}
}
