My website is to be a one page website, with 5 DIV's acting as panels (with a classname as .panel) that fit to stretch the full height and width of the browser window. My below code does this already and works a treat however, I have content that can be larger than the height of .panel/browser window. At the moment this content gets hidden. I.e. The .panel DIV is literally the height of the window and nothing else. I need it to expand if the content within it is larger than the height of the browser window.
How do I edit this code below to do add this functionality? Maybe add a classname to this adjusted DIV so that I can style it accordingly?
// In my plugins.js file
function fitElements(){
var height=$(window).height();
var width=$(window).width();
$('.panel').css('height',height);
$('.panel').css('width',width)
};
// At the bottom of my HTML file (to call the function)
jQuery(document).ready(function($) {
fitElements();
});
// My current code also adjusts on browser resize - so would need this answer to do the same
$(window).resize(fitElements);
Change the section
$('.panel').css('height',height);
to
if (height > $('.panel').height) {
$('.panel').css('height',height);
}
for the re-size function add
$('.panel').css('height','auto');
in to the beginning of the function

I need to adjust several elements in width and height in relation to window width. So I am using
window.onload = function() {
slideSizeUpdate();
};
$(window).resize(slideSizeUpdate);
to call my function.
After window resize everything is displayed correctly - but not onload. I guessed that this had something to do with the window-width-value.
So, I printed the width value of window and recognized that - onload - my window width had a value 'x' and when I resized for 1px left or right value 'x' of window width increased / decreased + / - 18px.
I assume that this causes the problems on my website onload. Does anybody know the reason for this and has anybody a solution how to fix it? That would be great!
EDIT
Its not that onload doesn't work at all. Its just the wrong values that it seems to get when it reads out the window width.
You can do like this:
$(window).on('load resize',function(){
slideSizeUpdate();
}).resize(); // trigger resize when page is loaded
Consider this scenario:
Some of the content is hidden via CSS. The resulting page is short and no horizontal scrollbar is required.
You calculate the window width on load event at which point scrollbars are not there.
You un-hide the content and now the page is tall and requires horizontal scrollbar.
The width of the window decreases by 17px (usual width of scrollbar) without you noticing.
If this is the case then one solution is to force the window horizontal scrollbar using CSS. You can use the following (although I recommend searching more on StackOverflow):
html {
overflow-y: scroll;
}
So I am redesigning my website: http://staging.slackrmedia.com/keenanpayne/, but I am coming across a small issue. I want each "pane" of the website to be the exact height of the window, no matter what the size. I also want the content therein to be exactly positioned in the center.
I am trying to accomplish this with jQuery at the moment:
function setSectionHeight() {
// Set section heights
windowHeightPadding = $(window).height() / 2;
firstSectionPadding = ($(window).height() - $('header').height()) / 2;
// Apply proper styling
$('section').css({"padding-top":windowHeightPadding,"padding-bottom":windowHeightPadding});
$('section.home').css({"padding-top": firstSectionPadding,"padding-bottom":windowHeightPadding});
}
setSectionHeight();
// Adjust section heights on window resize
$(window).on('resize', function(){
setSectionHeight();
});
So what this is doing is calculating the window height and dividing it by 2, so I can set the top and bottom padding on each section.
However, for the first section, to get the proper top and bottom padding, I need to subtract the height of the header, which is why I have a firstSectionPadding variable.
Then I just add the CSS to each section tag on my website, with separate styling for the home section tag.
This works pretty well, but as you can see when you visit my site, for some reason the heights are not correct.
Right now it looks like:
And it should look like:
I have absolutely no idea where this extra padding or space is coming from on the top. I think my equations are right, but perhaps there isn't something I'm taking into consideration?
This could be done with CSS. One div set to 100% height and width, with text-align:center; A second div within set to display:table and 100% height and width. Finally, a third div set to display:table-cell and vertical-align:center;
I am building a wordpress template, and I use a little Javascript to make the 'content' element fill the page from top to bottom. The goal is to cover the background image, so the 'content' doesn't look cut above the edge on larger screens. The code is:
$(document).ready(function() {
var h = Math.max($(window).height()+50, $("#content").height());
$("#content").height(h);
});
$(window).resize(function() {
var h = Math.max($(window).height()+50, $("#content").height());
$("#content").height(h);
});
My layout is: fixed sidebar on the left, then content with auto-width and two floated columns inside. It generally works, however on pages where I have a nivo-slider in one of the columns, the document height is determined incorrectly. When the screen size is small, the other column lands underneath (#media statement) and I can't scroll the screen to see that column.
See example page here: http://figtreephotodesign.com/kidsandfamilies/about/ - and set your browser window below 860px-wide to see the problem.
On another page: http://figtreephotodesign.com/kidsandfamilies/contact/ - it works (there is no nivo-slider).
Is it the nivo-slider's css messing up?
We needed a footer toolbar that stays at the bottom of the page, and sticks to some area when page is scrolled below that area.
We did achieved this using following script:
fixed div on bottom of page that stops in given place
But there is an issue on some page where the footer toolbar just disappears from the page, and then appear again when page is scrolled down further.
We found that this particular issue appears only on few page, when the page has some contents like Images, Video, or Ajax load other content where the content is filled in (or space is being filled) after page has loaded.
I have no clue how to fix this.
Here is the link from live site with problem page.

It is usually more visible on blog posts with many comments. May be due to Disqus comments being loaded after the page has loaded completely.
How does this look?
http://jsfiddle.net/LukeGT/NxSc3/
$(window).scroll(function() {
$('#bar').css('position', 'static');
console.log($('#bar').position().top);
console.log($(window).scrollTop() + $(window).height());
if ($(window).scrollTop() + $(window).height() < $('#bar').position().top + $('#bar').height()) {
$('#bar').css('position', 'fixed');
}
});
setTimeout(function() {
$('#extra').show();
}, 1000);
I simulated the late loading of images by just showing a few extra divs after 1 second. I believe the problem arises from the fact that the height of the page changes after the code for the bar runs, so it's behaving as it should if the page were shorter (without the images/ajax etc).
What I do instead is position the bar in it's place at the bottom of the page each time the page is scrolled, calculate its height from the top there, and compare this with the scroll height. If we're too far up, it positions the bar in a fixed position at the base of the page, and otherwise leaves it alone. It works smoothly in Chrome, but I haven't tested elsewhere.
I guess this is a problem with the $(window).height() function. Check here. For all the dynamic contents like Images, Video or Ajax-loaded content the height is not added to the result of $(window).height() unless it is specified somewhere in the HTML or CSS (and from the referred link I see this happens only in Chrome. You might want to confirm on this though). To those dynamic contents you can either try adding the height attribute in html or height attribute in the corresponding style.
This is not the answer but i have found something while inspecting your website...
This is you actual HTML when its working fine as you want..
<div class="footer-toolbar-container" id="sticky_for_a_while" style="position: fixed; ">
but when it is not working, the Position attribute is changing from Fixed to Relative .
<div class="footer-toolbar-container" id="sticky_for_a_while" style="position: relative; ">
you can check you script for that or post you script here...
At initial state, your div is in position: relative so its offset is based on the container element, not on the total height of the page. The variable stickyOffset is set based on that relative offset, that is why it gets clip down sooner than expected while scrolling and also why it works in your JSFiddle as the container there is the page (Iframe) itself.
In your $(document).ready function, you'll need to add the offset of not only the footer but also the rest of the offset on top of the containing element so that the offset is based on the total page instead of the containing div.
Hope that helps.
By looking at your example on http://www.sandiegopchelp.com/services/cellphone-repair/htc/ using chrome, I can see that your footer disappears when it gets at the "related links" section. At this moment, you set the position of the footer to "relative" so it will replace it in the regular flow of the document and its position is actually below the "related links" section which is why it disappears off screen (below "related links").
but you calculated the position at which it should become relative on page load only where you should have recalculated it after having added the "related links" section as it changes the page height (I understood that you added afterward, am I right?).
Try adding a zero height div just above the position of the sticky div, which will remain at that position as the page resizes, then check that position as you scroll to determine the position where the sticky div should stop.
Finally got it fixed by two techniques, setting explicit height wherever possible using CSS and delaying jQuery function after all images are loaded. Refer this: Delay some jQuery function until all images are loaded completely
Problem description: I got a page with a table containing text and thumbnails. Usually the table contains more entries than would fit on the screen leading to a scrollbar on the right side. No Problem so far. When loading the page or choosing the next page of the table (pagination) the table gets rendered - the scrollbar is at the bottom of the page where i would like it to be after complete load. Then the thumbnails are getting shown. Due to the fact that they are a bit bigger in size than the text in the table the table gets bigger in heigth leading to the scrollbar being set somewhere in the middle of the page.
Page and table after the images have been loaded, as you can see the scrollbar is somewhere in the middle (vertical) of the page:
I do not want to fiddle around with the thumbnail size. Customers are used to the actual design and image/icon sizes.
Usign the pagination function the table is the only element that gets replaced ont he page. "onload" on tables does not work unfortunatly.
What can i do to have the scrollbar appear after the images have been loaded (leading to the correct placement of the scrollbar)?
Is there a way to set the scrollbar to the bottom of the page after the table has been fully loaded?
There are jQuery plugins to wait for all images to be loaded, but I couldn't get them working on the quick, maybe you can: here and here.
However, you also could use the following hack: watch for the table height and if it changes, scroll to the bottom:
var lastHeight;
function watchTable(){
var currentHeight = $('#myTable').height();
if(currentHeight !== lastHeight){
lastHeight = currentHeight;
$('#myDiv').scrollTop(currentHeight);
}
}
setInterval(watchTable, 100);
see my demo fiddle for a working example.
The best practice is to set the widths of thumbnails in HTML or CSS, if all the thumbnails are of the same size, you can just add the style like
.thumbnail {
width: 150px;
height: 100px;
}
Or, if they size can vary, you must add width and height attributes to the ` tag.
Another solution is to:
Look at the document's scrolltop on DOMload, and look if it's at the bottom, then on onload event (which would be fired when all the images loaded) check again and if scroll to the desired position if needed.
But I recommend always set the dimensions for images, so the page wouldn't jump when they are loaded.
Edit: If you're loading images dynamically, you can do two things:
Preload images and then insert them with the right dimensions.
Use onload for images, however, you still would need to use the document.createElement('img'), so you could be sure that all the images are loaded.
Anyway, in these cases you should use something like that for each image:
var image = document.createElement('img');
image.onload = function () {
// Image is loaded
};
image.src = 'test.jpg';
Note, that you must set .src after attaching the event, or there could be some problems in Opera.
