how to automatically scroll down a html page?
Matthew Martinez
I'm trying to start each page after the homepage about 500px down, similar to this website:
You'll notice when viewing pages after the homepage, you're automatically scrolled down without notice but you can than scroll up to revel the featured slider again.
I've played with scrolledHeight but I dont think that is what I need????
Basically I have a featured section that is on top of all my content pages, but you shouldn't be able to see this section until you scroll up. Any help?

You can use .scrollIntoView() for this. It will bring a specific element into the viewport.
Example:
document.getElementById( 'bottom' ).scrollIntoView();Demo:
Script:
function top() { document.getElementById( 'top' ).scrollIntoView();
};
function bottom() { document.getElementById( 'bottom' ).scrollIntoView(); window.setTimeout( function () { top(); }, 2000 );
};
bottom();HTML:
<div>top</div>
<div>bottom</div>CSS:
#top { border: 1px solid black; height: 3000px;
}
#bottom { border: 1px solid red;
} 2 You can use two different techniques to achieve this.
The first one is with javascript: set the scrollTop property of the scrollable element (e.g. document.body.scrollTop = 1000;).
The second is setting the link to point to a specific id in the page e.g.
<a href="mypage.html#sectionOne">section one</a>Then if in your target page you'll have that ID the page will be scrolled automatically.
4here is the example using Pure JavaScript
function scrollpage() { function f() { window.scrollTo(0,i); if(status==0) { i=i+40; if(i>=Height){ status=1; } } else { i=i-40; if(i<=1){ status=0; } // if you don't want continue scroll then remove this line } setTimeout( f, 0.01 ); }f();
}
var Height=document.documentElement.scrollHeight;
var i=1,j=Height,status=0;
scrollpage();
</script><style type="text/css"> #top { border: 1px solid black; height: 20000px; } #bottom { border: 1px solid red; }
</style><div>top</div>
<div>bottom</div> Use document.scrollTop to change the position of the document. Set the scrollTop of the document equal to the bottom of the featured section of your site
