I've got HTML+CSS code. I need 1st div (row-1, white colored) to take first half of the container height, and 2nd div (row-2, orange-colored) to take the second part.
Here is my html:
http://pastebin.com/ipiEKHBZ
and my css:
http://pastebin.com/jtxw695F
Revised answer: After realising the default approach did not work with your HTML, this should work. You have classes .content-row-1 and 2 respectively. You can use those to tell the corresponding rows to always use a certain portion of the height. For this to work you also need to manually fix the positioning. (Someone correct me if this can be done more elegantly) For example those classes could look something like:
.content-row-1 {
background: #eee;
position: absolute;
top: 10%;
display: block;
height: 40%;
width: 100%;
}
I noticed that your footer already takes 10% of the height and and assumed you did not want any overlap or gaps. For that to work you should also give your header a percentage for height (10% in my example to keep things simple).
And for the future: try using https://jsfiddle.net/ when showing your code samples. I put it together at https://jsfiddle.net/kvbyk3f1/.
Is there a way to decouple css's max-height and max-width from the limits used by JQuery-UI's resizable()?
I have a div that, when initially created, should be limited in size:
.my-div {
max-width: 40em;
max-height: 50%;
}
I want it to be resizable beyond its initial size, but unfortunately resizable() seems to use these attributes to also determine the maximum size for resizing. Trying to override that by passing maxHeight and maxWidth options doesn't work. Is there a way to solve this, or some other-work around that will allow me to limit the initial size of the div and later on allow it to increase via resizable()?
I've found an identical question on jquery.com, but it's unanswered there.
A small reproducing jsfiddle - how can I allow resizing the div to see the ".com" suffix, while keeping only the "stackoverflow" word visible at first?
Did you try resetting CSS values via jQuery (not tested) ?
$(".my-div").css({
"max-width": "60em",
"max-height": "75%"
});
Update :
From you fiddle, I tried this :
.my-div {
width: 90px;
max-width: 130px;
overflow: hidden;
background-color: yellow;
}
Could it solve your problem ?
I ended up just implementing the "maximum" logic on the div manually to limit its size, instead of relying on max-width:
if ($div.width() > limit) $div.css('width', limit);

I would like to zoom in div by clicking on it, but part of this block is hidden after zoom.
Demo: http://jsbin.com/xumuzine/2/edit
CSS property transform-origin: 0 0; is not suitable, because in the future I will need to track the location where I clicked and increase it to this place.
Thanks.
UPD:
Okay, guys.
I may not accurately explained the problem.
http://jsbin.com/fecaduxidele/2/edit
Here i add click event handler that receives the coordinates of the click, and makes zoom to click position.
And if I click to cell with number 9 (for example), I can't scroll my grid to cell with number 1.
You could set the content size directly instead of scaling and use background-size to scale the image with it, e.g.:
#content {
width: 300px;
height: 300px;
background: url(http://placeimg.com/300/300/any);
background-size: 100%;
}
#content.scaled {
width: 450px;
height: 450px;
/* -webkit-transform: scale(1.5); */
-webkit-transition: all .5s ease-in-out;
}
Edit:
The above already fixes the issue of not being able to scroll to part of the image. You can handle the coordinate issue with a JQuery animation (you can't control scroll position from CSS), but it will not be smooth because it does not synchronize with the CSS animation. Your click handler would be something like:
var x = event.clientX,
y = event.clientY,
$this = $(this),
scaling = !$this.hasClass('scaled');
$this.toggleClass('scaled');
if (scaling) {
$this.parent().animate({
scrollLeft: x,
scrollTop: y
}, 500);
}
Here is the result applied to your second bin:
http://jsbin.com/jikididizice/1/edit
The issue was if the parent and the child is of same size its will show a scroller as you can see in this fiddle
JS Bin
as you can see in the above fiddle i have added scroll and the width and height is same as the parent in px so the scroller is coming
the fix is you can give 100% width and height like in the example i have shown below
if you dont want the scroller to come you can remove overflow:auto from the parent
JS Bin
you can also use transform-origin property to from where you want to scale the image like i have used center center in the example below so that it will scale from center
JS Bin
Few solutions:
Remove the overflow auto of the wrapper.
http://jsbin.com/xumuzine/40/
Scale the wrapper instead of the contents.
http://jsbin.com/mojoyapamuyi/1/
You should try with zoom property:
#content.scaled {
zoom:1.2;
}
any idea why in the example below, media queries stops changing the height of the menu bar after it's been changed by js? (make window small and click on the arrow to expand the mini menu). Do I need to register a point of origin for the menu element or something?
CSS:
#menu {
position: fixed;
left: 0px;
bottom: 0px;
width: 100%;
height: 90px;
z-index: 11000;
opacity: 1;
background-color: #F03600;
}
JS:
if ($("#arrowup").css('top') == '0px') {
$("#menu").animate({'height':'270px'}, 800, "easeInOutQuint");
} else {
$("#menu").animate({'height':'55px'}, 800, "easeInOutQuint");
}
You can check out the page here, all the code's on a single page:
http://www.nioute.co.uk/stuff/
Also, what's a good read with regards to media queries / js interaction?
Thanks!
The reason the media queries don't work is because when you modify the bar with Javascript, it applies inline-css. This overrides CSS that you may have in your stylesheets. The problem seems to be, when you toggle the arrow back down, #menu has an inline style of height="55px" applied to it, which blocks the regular style of 90px on a larger size.
The solution would be to clear the style when the window is resized to larger than your media query breakpoint using something like $(window).resize(function()...); and checking the current width of the window against your breakpoint. If it returns true, call $('#menu').attr('style', ''); and that will remove the inline style.
You can use class for adding some styles to elements and removing they after the job instead of getElementById(#menu).style.height = ...
for example:
getElementById(#menu).classList.add("newHeight")
Or
getElementById(#menu).classList.remove("newHeight")
Here's a link to what I'll be referring to.
I'm having some trouble getting the background image to work the way I'd like it to.
I want the background to auto resize based on the width of the window, which it is already doing correctly. If you make your window smaller you'll see the background shrink with it.
Here's the issue. If you make your window wide (short) then the background will resize and go too high so you can't see the top of the background anymore (since the background is bottom positioned).
I want the background to be top position when you are at the top of the page, and as you scroll down it will slowly move to be bottom positioned. Sort of like the effect of an Android phone's background when you move left and right. Of course, keep in mind that I still want the background to auto-resize when you make the window smaller.
html {
background-color: #70d4e3;
height: 100%;
}
body {
height: 100%;
}
.background {
margin-top: 45px;
width: 100%;
position: fixed;
bottom: 0;
left: 0;
z-index: -9999;
}
.banner {
margin: 0px auto;
width: 991px;
margin-bottom: -9px;
}
.content {
background: url("http://i.imgur.com/daRJl.png") no-repeat scroll center center transparent;
height: 889px;
margin: 0 auto;
width: 869px;
}
.innerContent {
padding: 30px;
}
<img src="http://i.imgur.com/6d5Cm.jpg" alt="" class="background" />
<div class="banner">
<img src="http://i.imgur.com/JptsZ.jpg" alt="" />
</div>
<div class="content">
<div class="innerContent">
testing
</div>
</div>
Maybe some javascript or jquery would be needed to achieve this.
Well, this was fun, thanks!
I hope you don't mind me taking the liberty to use percentages to make my life a little bit easier and possibly the script slightly more robust since I can reliably use floats with percentages.
What I did is make the layout, html and css comply with the rules you need for the bg to be animated properly, they stayed largely the same from what you had.
Then it was just a question of figuring out the calculations needed with the right properties to figure out the percentage you were from the top, the *20 is actually the amount of space 'left' to fill by the background image in percentages (as the background height is 80%).
They I moved the calculations to a function so I could call that on scroll and on window resize, making sure it's initiated on any event that modifies the window somehow...
Didn't do extensive testing but it worked in Chrome and I'm tired :p
I believe this is what you are looking for:
http://jsfiddle.net/sg3s/RSqrw/15/ See edit 2
If you wanted this the other way arround just make the page background start at the top and modify that:
http://jsfiddle.net/sg3s/RSqrw/14/ See edit 2
Edit:
As a bonus, and since I had never actually written jquery script as a 'plugin', I decided to convert this into one. What I came up with should be easy to implement and use!
http://jsfiddle.net/sg3s/RSqrw/52/ See Edit 3
Functionality successfully tested in Chrome, Firefox 3.6, IE9 + compatibility mode
Edit 2:
Reading the question again checking if I did it right I noticed I didn't quite do what you want, so I updated the link in the first edit which gives you a plugin in which you can have several options for the scrolling background. It retains my 'old' interpetation while also doing what you want... Read comments in code for some extra descriptions.
Edit 3:
As I went to work today I was bothered with the fact that my plugin 'try' was a little bloated. And as you mentioned in the comment it didn't quite fit the requirements.
So I rewrote it to only do what you want and not much more, tested in Chrome Firefox, IE9 +compat etc etc.. This script is a lot cleaner.
http://jsfiddle.net/sg3s/vZxHW/
You can chose to make the background stick to the top or bottom if the height fits in the window. Nothing else, but that is already more than enough to do some pretty cool stuff :p
An exact solution: Fiddle: http://jsfiddle.net/srGHE/2/show/

Thanks for the challenge. See below for the solution, which is complying with all requirements, including recommended yet optional (with steps on how to remove these) features. I only show the changed parts of your page, with an explanation after each section (CSS, HTML and JavaScript):
CSS (changes):
html,body{
margin: 0;
height: 100%;
padding: 0;
}
body{
background-color: #70d4e3;
}
#background { /*Previously: .background*/
/*Removed: margin-top: 45px;
No other changes*/
}
#banner /*Previously: .banner; no other changes */
#content /*Previously: .content; no other changes */
#innerContent /*Previously: .innerContent; no other changes */
Explanation of CSS revisions:
margin-top:45px at the background is unnecessary, since you're absolutely positioning the element.
All of the elements which are unlikely to appear more than once should be selected via the id (#) selector. This selector is more specific than the class selector.
HTML (changes):
All of the class attributes have been replaced by id. No other changes have been made. Don't forget to include the JQuery framework, because I've implemented your wishes using JQuery.
JavaScript (new):
Note: I have added a feature which you didn't request, but seems logical. The code will automatically reserve sufficient margin at the left side of the window in order to always display the background. Remove anything between the marked comments if you don't want this feature.
$(document).ready(function(){
//"Static" variables
var background = $("#background");
var marginTop = parseFloat(background.css("margin-top")) || 0;
var bannerWidth = $("#banner").width(); /*Part of auto left-margin */
var extraContWidth = (bannerWidth - $("#content").width())/2; /*Same as above*/
function fixBG(){
var bodyWidth = $("body").width();
var body_bg_width_ratio = bodyWidth/1920;
var bgHeight = body_bg_width_ratio * 926; //Calcs the visible height of BG
var height = $(document).height();
var docHeight = $(window).height();
var difHeight = bgHeight - docHeight;
var scrollDif = $(document).scrollTop() / (height - docHeight) || 0;
/*Start of automatic left-margin*/
var arrowWidth = body_bg_width_ratio * 115; //Arrow width
if(bodyWidth - bannerWidth > arrowWidth*2){
$("body > div").css("margin-left", "auto");
} else {
$("body > #banner").css("margin-left", arrowWidth+"px");
$("body > #content").css("margin-left", (arrowWidth+extraContWidth)+"px");
}
/*End of automatic left-margin*/
if(difHeight > 0){
background.css({top:(-scrollDif*difHeight-marginTop)+"px", bottom:""});
} else {
background.css({top:"", bottom:"0"});
}
}
$(window).resize(fixBG);
$(window).scroll(fixBG);
fixBG();
});
Explanation of the JavaScript code
The size of the background is determined by calculating the ratio of the background and document width. The width property is used, because it's the most reliable method for the calculation.
Then, the height of the viewport, document body and background is calculated. If applicable, the scrolling offset is also calculated, to prepare the movement of the background, if necessary.
Optionally, the code determines whether it's necessary to adjust the left margin (to keep the background visible at a narrow window).
Finally, if the background arrow has a greater height than the document's body, the background is moved accordingly, taking the scrolling position into account. The arrow starts at the top of the document, and will move up as the user scrolls (so that the bottom side of the arrow will be the bottom of the page when the user has fully scrolled down). If it's unnecessary to move the background, because it already suits well, the background will be positioned at the bottom of the page.
When the page has finished loading, this functionality is added to the Resize and scroll events, so that the background is always at the right location.
If you've got any other questions, feel free to ask them.
well, I'm not sure if I understand you and why do you want to do that, but you can try adding 2 backgrounds (see http://www.css3.info/preview/multiple-backgrounds/ ), one with the top bg and another with the bottom bg but I think that if the page is not too long it will cause issues, so the other answer with pure CSS is as follows: first add 3 horizontal divs with 100% width. Top div will have your top bg and its height, middle div will be transparent and auto height and bottom div will have your bottom bg and its height. All divs will have a 0 z-index. Then create a higher z-index div to act as a container and you'll be set. If I understand your question right, that's the close I can think of to achieve that. This being said, I'm pretty sure you can do this with JQuery with way better results
Using jQuery I was able to give you what I think you're asking for:
$(window).scroll(function() {
var h = Math.max($(document).height(), $(window).height());
var bottom = h - $(".background").height() - $(window).height();
$(".background").css("top", (($(window).scrollTop() / h) * bottom) + "px");
});
EDIT: Forgot to account for the way scrollTop reports position.
Or maybe:
.background {
margin-top: 45px;
max-width: 100%;
position: fixed;
bottom: 0;
left: 0;
z-index: -9999;
max-height: 100%;
}
I reccomend using jQuery Background Parallax
http://www.stevefenton.co.uk/Content/Jquery-Background-Parallax/
The function is as simple as
$("body").backgroundparallax();
Ask if you don't get it to work.
#abney; as i understand your question may that's you want http://jsfiddle.net/sandeep/RSqrw/60/
you need only css for this:
#background {
position: fixed;
width: 100%;
height:100%;
top: 0;
left:0;
z-index: -1;
}
