Going over the window height increases the elements width?

Question

I have nothing on the page except two section elements. Both the sections take up 1280px of width and 800px of height. When I shrink the browser window width down to 1281px (using Chrome's Dev tool to see the window's width), a horizontal scroll bar appears as if I had shrank the windows width below 1280px. When I inspect the body element it shows me that it is 1264px in width. On the other hand, Dev Tool shows me that the window width is 1281px.

When I decrease the height of both the section elements to a value lower than the window's current height, for example 300px, the horizontal scroll bar disappears and the body width is shown to be 1281px.

I have also applied css reset on the page as well.

what is causing this and how to prevent this?

section#sec1{
    background: orange;
}

section#sec2{
    background: pink;
}

section{
    display: block;
    margin:0px auto;
    width:1280px;
    height:800px;
}

<section id="sec1">Some content</section>
<section id="sec2">Other content</section>

Please post all of your CSS (what reset are you using for example?). Even better, can you create a jsfiddle? Clearly the problem is something other than the CSS/HTML you have posted, but it is impossible to say what unless we can see it. — Josef Engelfrost, Oct 25 '15 at 21:20

You can remove the horizontal scroll bar using:

 overflow: hidden;

This might prevent the issue you are facing.

This does not explain why the horizontal scrolling is happening (which is very difficult when the question is lacking information). – Josef Engelfrost Oct 25 '15 at 21:21
