Webpage not sizing correctly when scaling down

I think the pictures i’m posting will demonstrate this better. Whenever I size down my browser, there’s still a scroll bar at the bottom that shows extra un-wanted background image.

CSS:

body {
    background-image: url(https://images.unsplash.com/photo-1506744038136-46273834b3fb?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=1950&q=80);
    background-size: cover;
    background-position: center;
    background-repeat: no-repeat;
    font-family: 'Montserrat', sans-serif;
    color: white;
    
}

html {
    height: 100%;
    box-shadow: inset 0 0 0 1000px rgba(0,0,0,.4);
}

#content {
    text-align: center;
    padding-top: 25%;
    text-shadow: 0px 4px 3px rgba(0,0,0,.3),
                 0px 8px 10px rgba(0,0,0,.1),
                 0px 10px 16px rgba(0,0,0,.1);
}

h1 {
    font-weight: 700;
    font-size: 5em;
    width: auto;
    padding: 0px, 0px, 0px, 0px;
}



hr {
    width: 960px;
    border-top: 1px solid #f8f8f8;
    border-bottom: 1px solid rgba(0,0,0,0.2);
}

Hello @jaredmonkman, I suppose the problem is that you haven’t specified what to do with the background image if it takes up too much space. You’ve set the background-repeat: no-repeat, you might have to use the overflow property. W3Schools article. Also, media queries are useful in this situation, although I’m not sure if you’ve done them.

@media only screen and (max-width: 600px)/*or whatever you want it*/{
/*Rules for when this is met*/
/*eg:*/
h1 {
  font-family: serif;
}

I hope this helps!
}

Also note that in this case, <hr> having a fixed width of 960px will always remain at 960px even if you resize your browser window.

You could use @media queries, or relative units (like percentages).

@media (max-width: 960px) {
  hr {
    width: 100%
  }
}

That’s up to you.
