Lets say I have a horizontal navigation bar that can have an arbitrary number of items in it. Now let say this page has a width of 1000px and all the items if displayed would be 1300px. Now what I would want to do is to take whatever elements are causing it to extend beyond the 1000px and put them into a drop down menu. The issue I am having is what is the best way to figure out how many element I would need to take to make sure everything fits in the window when the window width can be changed (if the user changes the window width, the number of elements in the drop down would increase or decrease) and the navigation element widths are random?
Something similar to google plus's side navigation, just horizontal instead fo vertical.
Put the navigation elements in a parent div whose overflow is set to hidden so the extra nav elements are hidden.
Then, find the items that are hidden using jquery and append them to your dropdown menu. See answer to this question: jQuery: How to get content not visible with overflow: hidden?
See my working example: http://jsfiddle.net/zSXTb. The basics:
var h = $("#container").height();
$("#container").find("div").each(function() {
if ($(this).position().top > h) {
$(this).clone().appendTo($("#extrasContent"));
}
});
Run this onload and when the window is resized.
Try using #media queries with the css - you get a lot of control regarding screen size. For example:
#media all and (max-width: 1000px){
/*insert normal css. e.g.:*/
body{
width: 700px;
}
}
You can use min-width instead of max-width.

I have a 3 column layout where I want the left and right columns to be collapsible. I want the following:
A smooth slide
Sidebars that have a percentage width
No visible reflow on the sidebar content
No white-space: nowrap;, as this will mess with the display of the sidebar content.
Allow for complex content inside the sidebar, not just simple text in a <p> tag as in the codepen example below.
No hardcoded pixel widths - I know you can add a width on an inner div together with overflow:hidden on the parent, but I don't want to hardcode a large width.
I need the sidebar widths to be relative to the immediate parent (and not the viewport), in case the 3-column layout needs to be within a section of a page (in fact in my scenario that's the case).
Note that the I've tried transitioning on the width property in this codepen, but you can see the visible reflow of content inside the sidebar. Here's a .gif of it:
Ideally I'd like to do this without using JavaScript for the animation, but I'm open to it if there are no other good solutions.
One way to do this I would say is to give a % based width to your pabel-content.
Add these two properties to the class like this
.panel-content {
min-width: 300px;
}
This should remove the wrapping while animation.
I want to have a menu that is toggable in small screen sizes and always visible on medium sizes upwards.
The behavior should be (basically) exactly like this demo here.
The steps are:
Go to a small screen size (til the body outline is gold)
Check that it's toggable
When the menu is hidden and you get a bigger screen size, the menu should appear
When the menu is not hidden, go to a bigger screen size and it should remain shown
When on a big screen size, and element was hidden, you should see it but when you drag to a smaller size, it should get hidden
When on a big screen size, and element was NOT hidden, you should see it but when you drag to a smaller size, it should get hidden
To achieve this is very easy with:
$(".click").click(function() {
$(".menu").toggleClass("hidden-md-down");
});
My problem now is that I want to animate this show and hide and I can't do it with the class toggle.
So I have to rely on for example slideToggle() and here is where my problem lies, see demo here.
If you now go to a small screen size, hide the menu and make the window size bigger, the menu won't appear because of the hide() function.
I know this could be solve with a $(window).resize but I definitely don't want that solution since it's terrible for performance for such a small feature.
So how can I either have this toggle class with an animation or do it with js without the resize method?
I've put my comment into an answer instead: "For best performance wire your window size check to only the end of the browser resize, not to every stage."
This code works and it only runs .5 sec after the end of the window resize event rather than during (better performance). Run the code full page and squeeze your browser window to see it in action.
Instead of sending the text values #width and #height you can elect to run your menu toggle or deactivate it; I'd do this by removing the js class you're using to activate the menu initially.
And make your menu an unordered list and set it to be inline on desktop and an unbulleted list on mobile using css.
$(window).resize(function() {
if(this.resizeTO) clearTimeout(this.resizeTO);
this.resizeTO = setTimeout(function() {
$(this).trigger('resizeEnd');
}, 500);
});
$(window).bind('resizeEnd', function() {
var widthReport = $("#width").text($(this).width());
var heightReport = $("#height").text($(this).height());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="width"></div>
<div id="height"></div>
I have a list of anchor elements (it's a page navigator at the bottom of the page). On mobile, the list wraps to two lines. I want to keep it at one line for easier mobile use, and display only the page numbers that will fit within the screen. I don't want to do whitespace: nowrap; or overflow-x: scroll -- I want to have as many elements as possible display on one line without scrolling or disappearing into the horizontal ether.
I was thinking I'd determine the window width with jQuery, and if the width of the list as a whole exceeds the width of the screen, show only the elements on either side of the active page div that will fit on one line. Is there such a thing as "select certain number of siblings"?
I know .siblings() exists in jQuery as well as the CSS sibling selector, but these either select all siblings or only the one immediately adjacent sibling. I want to dynamically select the siblings on either side of the active element (page) depending on screen size.
Without any code, it's hard to tell exactly what you're doing. But I would use whitespace: nowrap; so that the elements are as wide as they can be, then you can loop through them and compare their width to the viewport or container width, and selectively hide them. (or alternatively, hide them by default with opacity: 0; or visibility: hidden; and only show the ones whose widths are less than the container/viewport). Something like this:
var cw = $('.container').width();
$('footer li').each(function() {
if ($(this).width() > cw) {
$(this).addClass('hidden');
}
});
You can set the width of each element to window width/number of items
var numberOfAnchors=$("a").length;
$("a").css("width",$(window).width()/numberOfAnchors+"px");
but make sure that the anchor display is different to display:inline
One of the divs which i want to display dynamically has to fit to screen. The problem is that if the earlier displayed div has height more than the screen height, when the dynamic div is displayed in the bottom of the page(after scrolling) there is some part of the earlier div still remaining. I dont want any trace of the earlier while displaying the dynamic div. Also i have to achieve this only by using javascript.
to place an div or any element one above another use position:absolute,top:0; left:0 and width and height to 100%
get the div out of your other divs, but still in the body and make it not visible "display:none;"
Give it some attributes, like Mardzis said, height : 100%; width : 100%; z-index:9999;
Then, when you want to display it, just do .show() or .hide() (with jquery if you use it) or .getElementById('#yourDivId').style.display = "none"; .... & so on...
I found a workaround for this.Put focus on the child div and disable scrolling.
I'm nearly 2 months old in studying HTML, JavaScript and jQuery. I've done a few things but never figured out how to implement a DIV (or anything you may suggest) to emulate a viewport which would display text, textarea, buttons, anchors etc all of which simply cannot fit or be seen within the size of the viewport. Therefore the use of the vertical scroll. No need for horizontal scrolling, though. I can format the objects not to exceed the horizontal view. I thought of using a div inside another div, but the objects inside the INNER DIV just bleed through and show up on the bottom of the site!
Is there some magical panel in jQuery created for that purpose?
TIA

If you have a containing div such as <div id="container">, you can add the following properties to it to get it's content to scroll vertically:
div#container {
overflow-y: auto;
height: 100px;
}
This CSS will show a vertical scroll bar if the div's content exceeds it's height. The only caveat with this solution is you must set a height on the div.
Here's an example.
