Find element that is causing the showing of horizontal scrollbar in Google Chrome

问题

When I size my Chrome window to 328 x 455 pixels I still see a horizontal scrollbar. How can I find out which element is causing this? I've been looking elements via the developer console, but can't find the element.

I then tried the script I found here, but nothing is logged. I tried it on element body, section1 and a bunch of others but don't know what else to do.

    $(function () {
        var f = $('body'); //document.getElementById("body");
        var contentHeight = f.scrollHeight;
        var declaredHeight = $(f).height();

        var contentWidth = f.scrollWidth;
        var declaredWidth = $(f).width();
        if (contentHeight > declaredHeight) {
            console.log("invalid height");
        }
        if (contentWidth > declaredWidth) {
            console.log("invalid width");
        }
    });

回答1:

.slide-content .scroller {
  width: 1024px;
}

"fastestest" way: added this in inspector:

* {
  border: 1px solid #f00 !important;
}

and the culprit appeared

There is an excellent article by Chris Coyier which explain everything you need about this problem.

after reading this article, I personally use this code in my console to find out which element cause vertical scroll:

press F12 in your Browser then choose console and copy paste this code there and press enter

var all = document.getElementsByTagName("*"), i = 0, rect, docWidth = document.documentElement.offsetWidth;
for (; i < all.length; i++) {
    rect = all[i].getBoundingClientRect();
    if (rect.right > docWidth || rect.left < 0){
        console.log(all[i]);
    }
}

Update:
it might be an element inside an iframe make page to vertically scroll. in this case you should check every suspected iframe with this code:

var frame = document.getElementsByTagName("iframe"); 
frame = frame[0];
frame = (frame.contentWindow || frame.contentDocument);
var all = frame.document.getElementsByTagName("*"), i = 0, rect, docWidth = document.documentElement.offsetWidth;
for (; i < all.length; i++) {
    rect = all[i].getBoundingClientRect();
    if (rect.right > docWidth || rect.left < 0){
        console.log(all[i]);
    }
}

My quick solution with jQuery, stijn de ryck's createXPathFromElement and the console:

/**
 * Show information about overflowing elements in the browser console.
 *
 * @author Nabil Kadimi
 */
var overflowing = [];
jQuery(':not(script)').filter(function() {
    return jQuery(this).width() > jQuery(window).width();
}).each(function(){
    overflowing.push({
        'xpath'    : createXPathFromElement(jQuery(this).get(0)),
        'width'    : jQuery(this).width(),
        'overflow' : jQuery(this).width() - jQuery(window).width()
    });
});
console.table(overflowing);


/**
  * Gets the Xpath of an HTML node
  *
  * @link https://stackoverflow.com/a/5178132/358906
  */
function createXPathFromElement(e){for(var t=document.getElementsByTagName("*"),a=[];e&&1==e.nodeType;e=e.parentNode)if(e.hasAttribute("id")){for(var s=0,l=0;l<t.length&&(t[l].hasAttribute("id")&&t[l].id==e.id&&s++,!(s>1));l++);if(1==s)return a.unshift('id("'+e.getAttribute("id")+'")'),a.join("/");a.unshift(e.localName.toLowerCase()+'[@id="'+e.getAttribute("id")+'"]')}else if(e.hasAttribute("class"))a.unshift(e.localName.toLowerCase()+'[@class="'+e.getAttribute("class")+'"]');else{for(i=1,sib=e.previousSibling;sib;sib=sib.previousSibling)sib.localName==e.localName&&i++;a.unshift(e.localName.toLowerCase()+"["+i+"]")}return a.length?"/"+a.join("/"):null}

Find the culprit by copy paste the below js code in your URL address bar.

javascript:(function(d){var w=d.documentElement.offsetWidth,t=d.createTreeWalker(d.body,NodeFilter.SHOW_ELEMENT),b;while(t.nextNode()){b=t.currentNode.getBoundingClientRect();if(b.right>w||b.left<0){t.currentNode.style.setProperty('outline','1px dotted red','important');console.log(t.currentNode);}};}(document));

Adding a border to everything made the problem go away for me. The culprit was a drop-down menu hidden with opacity: 0. I actually found it by process of elimination - delete elements in DevTools one by one, starting with parent elements and moving down the tree.

But now I know the problem, this would have done it for me:

* {
  opacity: 1 !important;
  visibility: visibile; !important;
}
