page not redrawing on horizontal scroll - javascript

When I shrink the width of my browser window (Firefox v26) so that only 1/2 of my home page is shown, the horizontal scrollbar appears on the bottom of the browser, which is fine.
But if I scroll the page to see its right half -- that right half is blank. In other words, after horizontally scrolling to the right (which moves the page's content leftward, obviously) -- the right side of the page does not redraw. It stays blank. Even if I hit the refresh on the browser URL bar.
I looked around and saw several posts. This one seemed to be exactly the same problem (only difference was, theirs involved the vertical scrollbar).
So I took the suggestion there -- which was to set my outermost content div (called wholePageDiv in the code below) and also my outerDiv to 'min-width: 100%" but this changed nothing.
Here's the very simple code:
<html>
<body>
<div id="wholePageDiv" class="wholePageDivForCentering">
<div id="outerDiv" style="margin: 0; margin-top: 10px; min-width: 100%;
display: inline-block; overflow: hidden">
(not shown: a bunch of divs with text)
</div>
</div>
</body>
<html>
Here is the wholePageDivForCentering CSS class, with the change made per that SO post I read:
.wholePageDivForCentering
{
/* width: 100%; */
min-width: 100%;
/* height: 100%; */
min-height: 100%;
white-space: nowrap;
margin: 0 auto;
}
I have looked at other websites to see if they exhibit the same "right side of scrolled page does not redraw" problem. On other websites I tested, I shrink the browser to 1/2 the width needed to show the whole page, then I scroll to see the right 1/2 of the page -- all other websites I check are successfully redrawing the right-side content as I scroll.
Do I have a CSS style problem above?
EDIT: I hit F12 in my browser and use the 'Inspector' tool and I clearly see that the only visible content is within the wholePageDiv and this div is not expanding at all, to the right, as I scroll to the right -- the Inspector shows that for whatever reason my outermost wholePageDiv is remaining the same fixed size as the viewport, and when I scroll to the right, this viewport outline as shown by the Inspector simply shifts leftward and does not expand on the right side to accommodate moving the scrollbar to the right.

I have added your html and css in a fiddle and it scrolls fine for me. The text of the div is displayed with no issues: http://jsfiddle.net/micahSan/UucLB/3/
same code as the OP
Can you replicate your problem in a fiddle so we can all see it?

I solved this (for now) by either hard-coding the div's width, or by programmatically increasing the div's width as the width of the browser window/document was changed. Hopefully will find a less kludgy solution later.

White Space occur only in mobile view because of scroll up icon

I am creating a website using a free template Click here to go on the website
When you scroll up after scroll down you will notice a red standing arrow at the bottom right corner this is an image of the red arrow on which if you hit it will scroll the page to top #Home.
Now the problem is on my laptop it looks ok but when I do inspect to see mobile view then I can notice a white space created by this feature.
this is the image :
Click here to see image
I already tried using :
html,body
{
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
overflow-x: hidden;
}
and notice that only overflow-x: hidden remove white space but also affect then arrow scroll functionality and also still little bit space persist towards right size with a bottom scrollbar.
I tried to remove the entire scroll code also but still unable to remove this white space which is occurring only in mobile view.
I gave a link to the entire website instead of mentioning here as I don't know which code is causing a problem and can't provide a code of entire website at here.
Please see the link and over there you will find the entire website with this scrolling feature on each page. Thanks
The image used as the background of your #toTop element is 32px wide, so change the width:
#toTop {
width: 32px;
}
If you need to push it away from the right hand side, use a margin-right.

Full background image initially fixed, then scrolls when DIV content ends

I'm trying to figure out how to have a full background image (background-size: cover) be fixed initially (the text over the image scrolls while the image stays put), but, at the moment when the user scrolls down to the end of the content (like a tall block of text), the background then scrolls up revealing a new section/div below.
For example:
<section id="top-section-with-fixed-bg">
<div class="tall-content-1500px">
<p>Text that's really tall</p>
</div>
</section>
<section id="next-section">
...
</section>
But, again, the background image is fixed until the user has scrolled down 1500px and the content for that section/div is done. At that point, the user continues to scroll and the background image scrolls up.
Not, as with parallax solutions, with the background image being covered by the next section. But the background image going up with the scroll.
I'm thinking this takes some javascript, jQuery fixing, but I'm still a bit novice with it. I'm a designer just wanting a site to look and act this certain way. I'm guessing I have to recognize the height of the content, where that ends, and then either tell the CSS to switch from fixed to scroll (without effecting the position of the image), or having the js move the image up with the scroll action.
Update: Here's a quickly tossed together jsfiddle
UPDATED UPDATE:
I think I've found the solution!
With the pointers provided in responses here, then some digging around, I have it kind of working.
I started with trying to figure out how to detect the window height. I plug that into the text/content DIV, using that value for the DIVs height. This is important, to set the container for the text to the height of the user's window, not to a specific height. Then, I set that DIV to overflow: auto (and hide the scrollbar, for aesthetics). That allowed me to set a trigger so when the end of the content in that DIV is reached, the background-attachment is changed from fixed to scroll.
And, voila! It's not perfect, and I'm sure some real javascript/jQuery experts will right my wrongs on it, but I like how far I've gotten with this so far.
I realize that the swtich from fixed to scroll is probably unnecessary. At the moment, when the switch happens, the image jumps a little to adjust to the window size and its own position, now being set to scroll. If I set the CSS originally to fixed, and make sure the content of the DIV (using padding wisely) to cover the window, as the user scrolls with the mouse the correct action will occur: text scrolls until there is no more text, then the image scrolls up.
Check it out and look forward to help and comments.

have you set background-attachment:fixed;? This makes background images 'move' with the browser scroll. Be careful when it comes to devices though as this method can cause 'laggy looking sites' because there's too much render for the device (depending on image).
I personally target 'large' and 'modern' browsers with this:
#media query and (max-width:600px){
.top-section-with-fixed-bg{background-attachment:fixed;}
}
EDIT:
sorry I didn't fully understand the question. Here's some CSS to get you going
window.addEventListener('scroll',function(){
//document.body.scrollTop would be the windows scroll position.
if(document.body.scrollTop==1500px)
document.getElementById('top-section-with-fixed-bg').style.backgroundAttachment='static';
}else document.getElementById('top-section-with-fixed-bg').style.backgroundAttachment='fixed';
});
I'm very sorry but this is very basic. I'm about to finish work. The function could use a bit of sprucing up a bit like making it dynamic. This is also only native JS. So it's not all that fancy but you get the idea. When the document.body.scrollTop is at the bottom of your element. Which I'm guessing is 1500px tall? IF not use offsetHeight(). That'll give you the complete height of the element including padding and margins and I think borders as well?
I'd set your background images to background-position: fixed; then put the next background image at the bottom of the text so it overlays on top of the first div. Problem is you can't have the nice <section> structure you had going before.
<style type="text/css">
.section-with-fixed-bg {
min-height: 100%;
background-size: cover;
background-attachment: fixed;
background-repeat: no-repeat;
background-position: center center;
}
#bg-1 {
background-image: url("./background-1.jpg");
}
#bg-2 {
background-image: url("./background-2.jpg");
}
#bg-2 {
background-image: url("./background-3.jpg");
}
</style>
...
<body>
<div id="bg-1" class="section-with-fixed-bg">
<p>Text that's really tall</p>
<div id="bg-2" class="section-with-fixed-bg">
<p>Next section of text that's really tall.</p>
<div id="bg-3" class="section-with-fixed-bg">
<p>Next section of text that's really tall.</p>
</div>
</div>
</div>
I haven't tested this but it should cause the new image to overlap the old one, at least in theory.

Flex layout - cell partially collapses in chrome

So I've got a bit of a weird issue which is happening in Chrome (latest version on Mac). Here is the fiddle which replicates it: http://jsfiddle.net/mwznjnoc/1/
You'll see that the search bar has a set height of 40px. However, as soon as the right side red cell has content which makes it scroll, it squishes the search bar. Moving the search bar outside of the div it is in and under the header div fixes the issue, but I cannot fix it that way (the search bar is part of the view content, which gets rendered in the div it is in). Removing height: 100%; from html and body stops it from happening, but is not the fix as I need the viewport height to be 100%. This layout works fine in other browsers I've tested it with, anyone have an idea why this is happening or a way to adjust the layout to prevent it? Thanks for your time in advance!
You forgot the flex rule on your .search box.
Because it being a part of flex, you should remove the style height:40px from the .search box.
Then provide flex-grow and flex-shrink as 0, and flex-basis as 40px.
You may combine all three into one as flex: 0 0 40px. This will force the layout to contain the .search box within 40px and let other blocks grow or shrink in the available space.
Changes in HTML Markup:
<div class="search">search bar</div> <!-- Remove inline style for height -->
Changes in CSS:
.search {
flex: 0 0 40px; /* add the flex rule here */
background: #ccc;
}

Get rid of useless scroll bars on fancybox iframe

I have some content I want to show in iframe with fancybox. When I use it, it pops up with horizontal and vertical scroll bars even though all the content is inside of it. Inspecting it in Firefox shows that when I click on html everything is inside but there is a little left over that is outside of the highlighted box. The next level up is iframe.fancybox-iframe which includes the scroll bars. I looked at the css and that has padding and margins set to zero so I don't know why the scroll bars are there. Right now as far as options I just have autoSize:false. All I have inside the body of the page I want to show is a form.
If anyone wonders which class name to use
.fancybox-inner {
overflow: hidden !important;
}
And if you found a small white background you can reset it using
.fancybox-skin {
background: inherit;
}
Try adding this to the css:
.style{
overflow: hidden;
}
If it didn't help, please post your HTML and CSS.

Relative Positioning at bottom of the screen issue with Flex and different browsers

I have a flex component like this:
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
...
width="100%"
height="100%"
creationComplete="init()">
.......
<components:NavigationBar id="nagivationBar"
left="0" bottom="0" />
This is supposed to show at the bottom left of the screen considering that parent container fills the screen.
The behaviour I just described shows perfectly with Safari
with Chrome it shows correctly if the download bar beneath is not visible but as soon as the download bar has something it covers the bottom part of it.
and FireFox seems to always hide like 50 pixels or so from the bottom of the screen.
It seems like every browser renders the 100% height in its own way.
What is your recommended best way to overcome this? I can add a 100 pixel margin at the bottom but it's not something I want to do in this application.
Try something like this in the <head></head> section of the HTML page that loads your Flex Application:
<style type="text/css">
html, body{
width: 100%; /* make the body expand to fill the visible window */
height: 100%;
padding: 0 0 0 0;
margin: 0 0 0 0;
overflow: hidden;
}
</style>
Not sure it will help in your case but it's easy to try.
You could wrap the output in a containing <div>, then using YUI's getClientRegion, and a resize event for good measure, set the containing div's CSS height property to the value which YUI has determined the available viewport vertical space.
Sorry the solution is an outside-of-Flex one, but it'll work.
Edit: I meant 'getViewportHeight()' not 'getClientRegion()', sorry, check out the APi docs though, there's plenty of goodies in there for this sort of stuff.
Flex is just a flash component in a web page. Its size depends of what is outside of flex. I don't think you'll get a proper answer unless you post HTML/JS code surrounding flex app.
PS. From my experience working with browser height may be very troublesome.
this normally happens when you have one or more positioning elements in a page. Check your code to see if you have used the position element anywhere else in your code, if so are they different, i.e one relative and the other absolute, if so this could be your problem, its reccomended that they are all the same, ie all relative
