When a user's browser has a width of less than 1160px, a media query is setup to collapse my site's right sidebar. They can get it back by clicking on a little arrow and then it will overlap the content (absolute positioning).
Anyway, I used the following jQuery to achieve this:
$('.right_sidebar_preview').on('click', function() {
$('.right_sidebar_preview').css('display', 'none');
$('.right_sidebar').css('display', 'block');
});
$('.right_sidebar').on('click', function() {
$('.right_sidebar_preview').css('display', 'block');
$('.right_sidebar').css('display', 'none');
});
So basically I already have the preview hidden when the browser is larger than 1160px and the sidebar is visible, in the media query I have it set up so when it's below 1160px, the sidebar becomes invisible and the "sidebar preview" is shown which users can click to make it bigger.
CSS:
.right_sidebar {
width: 242px;
height: 100%;
background-color: #d8e1ef;
float: right;
position: relative;
}
.right_sidebar_preview {
display: none;
}
#media(max-width:1160px) {
.right_sidebar {
position: absolute;
right: 0;
display: none;
}
.right_sidebar_preview {
display: block;
background-color: #d8e1ef;
position: absolute;
right: 0;
width: 15px;
height: 100%;
}
}
My question is, when I use the code above, let's say we're in the less than 1160px media query, I'll open the sidebar then collapse it again, and when I stretch my browser out to go back, it also closed the sidebar on the greater than 1160px media query.
So is there anyway I can use .css() (or an alternative method) to point at a specific media query?
Do not manipulate the CSS display: property. Instead, use CSS classes to control the visibility of sidebar and its handle. This way you can use your media query to control whether an element displays or not.
In the following demo, click the "Full page" button to see how this works on screens > 1160px.
$(function() {
$('.right_sidebar, .right_preview').on('click', function() {
$('.right_sidebar, .right_preview').toggleClass('lt-1160-hide lt-1160-show');
});
});
.right_sidebar {
width: 100px;
height: 100px;
background-color: papayawhip;
float: left;
display: block;
}
.right_preview {
width: 20px;
height: 100px;
background-color: palegoldenrod;
float: left;
display: none;
}
#media(max-width: 1160px) {
/* note: the following rules do not apply on larger screens */
.right_sidebar.lt-1160-show, .right_preview.lt-1160-show {
display: block;
}
.right_sidebar.lt-1160-hide, .right_preview.lt-1160-hide {
display: none;
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="right_sidebar lt-1160-hide">Sidebar</div>
<div class="right_preview lt-1160-show">›</div>
On a recent project, I had to process a single function in jQuery based on the browser size. Initially I was going to check the device width was applicable to a mobile device (320px):
jQuery
$(window).resize(function(){
if ($(window).width() <= 320) {
// your code here
}
});
or
$(window).resize(function(){
if ($('header').width() == 320 ){
// your code here
}
});
Something like this?
$(window).resize(function(){
if ($(window).width() <= 1160){
// lets party
}
});

My problem is along the lines of these previous issues on StackOverflow but with a slight difference.
Previous issues:
Stopping fixed position scrolling at a certain point?
Sticky subnav when scrolling past, breaks on resize
I have a sub nav that starts at a certain position in the page. When the page is scrolled the sub nav needs to stop 127px from the top. Most of the solutions I have found need you to specify the 'y' position of the sub nav first. The problem with this is that my sub nav will be starting from different positions on different pages.
This is the JS code i'm currently using. This works fine for one page but not all. Plus on mobile the values would be different again.
var num = 660; //number of pixels before modifying styles
$(window).bind('scroll', function () {
if ($(window).scrollTop() > num) {
$('.menu').addClass('fixed');
} else {
$('.menu').removeClass('fixed');
}
});
I'm looking for a solution that stops the sub nav 127px from the top no matter where on the page it started from.
You can use position: sticky and set the top of the sub-nav to 127px.
See example below:
body {
margin: 0;
}
.main-nav {
width: 100%;
height: 100px;
background-color: lime;
position: sticky;
top: 0;
}
.sub-nav {
position: sticky;
width: 100%;
height: 50px;
background-color: red;
top: 100px;
}
.contents {
width: 100%;
height: 100vh;
background-color: black;
color: white;
}
.contents p {
margin: 0;
}
<nav class="main-nav">Main-nav</nav>
<div class="contents">
<p>Contents</p>
</div>
<nav class="sub-nav">Sub-nav</nav>
<div class="contents">
<p>More contents</p>
</div>
Please see browser support for sticky here
You should change your code to the below, should work fine:
$(window).bind('scroll', function () {
if ($(window).scrollTop() > $(".menu").offset().top) {
$('.menu').addClass('fixed');
} else {
$('.menu').removeClass('fixed');
}
});
Maybe you can try this:
Find navigation div (.menu)
Find the top value of the .menu (vanilla JS would be menuVar.getBoundingClientRect().top, not sure how jQuery does this).
Get top value of browserscreen.
Calculate the difference - 127px.
When the user scrolls and reaches the top value of the menu -127px -> addClass('fixed').
The problem:
I have a form with a button underneath it to submit (post) from data with jQuery ajax(). I want for the button to be replaced with a spinner (animated png) for the duration of server ajax call. But such a trivial task is impossible in css to do right.
What i have tried:
I have placed button and image inside a bootstrap row. Ox ajax call I have set button display to none and img display to block. But because this two are not of the same size makes the whole page flicker, breaks the positioning of other elements and so on.
Another idea was to try to place both elements on top of each other with absolute positioning. But, stupid as css is I cannot center it on the middle of the row.
Is there a way to position both elements on top of each other so I can control their visibility?
Please bear in mind that I cannot used absolute position in pixel, because this is a web page and I do not not how wide the browser will be, image can change in the future, text in the button can change in the future, all this things affect absolute size.
If there is another solution to my problem which would prevent the page from jumping up and down it would also be great.
EDIT
Link to one of fiddle experiments:
https://jsfiddle.net/ofb2qdt8/
.button {
position: relative;
margin: auto;
height: 50px;
width: 30px;
background: blue;
z-index: 1;
display: block;
}
.spinner {
position: relative;
margin: auto;
height: 30px;
width: 50px;
background:red;
z-index: 2;
}
This renders second element underneath on screen. Not on different z layer.
Experiment 2:
https://jsfiddle.net/ofb2qdt8/
.button {
position: absolute;
margin: auto;
height: 50px;
width: 30px;
background: blue;
z-index: 1;
display: block;
}
.spinner {
position: absolute;
margin: auto;
height: 30px;
width: 50px;
background:red;
z-index: 2;
}
This does not center both elements, and they are pushed to the top of the containing div. The element with less height should be centered.
Check this working demo: https://jsfiddle.net/ofb2qdt8/3/
Add in a few lines of jquery and update your css.
Position your loading div according to button div's position, width, height using jquery.
*Click the button to see loading div, and try to play the margin of the button to any pixel.
###JQUERY
$(document).ready(function () {
$('.c2').each(function () {
$(this).css({
'width': $(this).siblings('.c1').outerWidth(),
'height': $(this).siblings('.c1').outerHeight(),
'top': $(this).siblings('.c1').offset().top,
'left': $(this).siblings('.c1').offset().left
});
});
$('.c2').on('click', function () {
$(this).hide(0);
});
});
###CSS
.c1 {
margin: 100px auto;
width: 100px;
text-align: center;
padding: 5px 10px;
background: blue;
z-index: 1;
}
.c2 {
position: fixed;
text-align: center;
background: red;
z-index: 2;
cursor: pointer;
}
Rough, ready and untested:
HTML
<div>
<input type='submit' />
<img src="spinneyIMage.gif" />
</div>
CSS
div{ text-align: center; }
div img{ display: none; }
jQuery
$('submit').click(function(e){
e.preventDefault();
$(this).hide().next().show();
});
After the Ajax call completes reverse the above jQuery.
As I haven't been able to find a working solution I have reverted to my first idea which I discarded at first. Albeit with a little twist.
HTML
<div class="row>
<div id="container-button" class="col-xs-12>
<button id="button" onclick="button_OnClick(e)">submit form via ajax</button>
<img src="img/spinner.png" sytle="display: none" />
</div>
</div>
JS
function btnContact_OnClick() {
// show the soinner and hide the button
showSpinner();
$.ajax(
{
type: 'POST',
url: "someurl.com/target",
data: $("#form").serialize(),
dataType: "json",
complete: function() { hideSpinner();},
success: onAjaxSuccess,
error : onAjaxError
});
}
function hideSpinner() {
$("#spinner").hide();
$("#button").show();
// make container height non-fixed and content adjustable again
$("#container-button").height('auto');
}
function showSpinner() {
// THis is the trick !!!
// Make the container fixed height as it was before displaying spinner, so it does not change with content (spinner is not the same height as button
$("#container-button").height($("#container-button").height());
$("#button").hide();
$("#spinner").show();
}
This is not the perfect solution but the best I could make.
Drawbacks:
it is not clean, you have to use javasript to fix what is css layout
problem
it still causes a little flicker
the height of container while displaying spinner is dependant on button, this may cause clipping if spinner is too big
This works and properly aligns the icons:
#stepSuccess {
display: table;
margin: auto;
}
#stepFailure {
display: table;
margin: auto;
}
Here are the icons themselves:
<i class='icon-ok icon-4x icon-green'id='stepSuccess'></i>
<i class='icon-remove icon-4x icon-red'id='stepFailure'></i>
However, I need it to be at display: none for javascript purposes. When I try the code below it does not align to the center after I use .show() to display the icon.
#stepSuccess {
display: none;
margin: 0 auto;
}
#stepFailure {
display: none;
margin: 0 auto;
}
Here is the jQuery
if(checked)
{
//display correct-answer dialogue
$("#stepSuccess").show();
{
else
{
//display wrong-answer dialogue
$("#stepFailure").show();
}
How do I keep display: none and still have the code properly align to the center of the div (after .show() in javascript)? I also tried text-align: center;
Any help would be appreciated.
I suspect that when you use .show(), it sets display: inline instead of display: table. Instead of .show(), I would set up two classes, one for show and one for hide, and toggle the class.
Alternatively, you could also use:
if(checked)
{
//display correct-answer dialogue
$("#stepSuccess").css('display','table');
{
else
{
//display wrong-answer dialogue
$("#stepFailure").css('display','table');
}
instead of .show().
For the sake of less code, would you be able to just set the opacity to 0, rather than hide?
I need to quickly knock up the functionality of the twitter bootstraps main navigation and sub navigation e.g. http://twitter.github.com/bootstrap/scaffolding.html (when you scroll the subnav becomes fixed to that main navigation)
Has anyone implemented this or are there any tutorials?
Here is my code to implement this feature:
$(document).scroll(function(){
// If has not activated (has no attribute "data-top"
if (!$('.subnav').attr('data-top')) {
// If already fixed, then do nothing
if ($('.subnav').hasClass('subnav-fixed')) return;
// Remember top position
var offset = $('.subnav').offset()
$('.subnav').attr('data-top', offset.top);
}
if ($('.subnav').attr('data-top') - $('.subnav').outerHeight() <= $(this).scrollTop())
$('.subnav').addClass('subnav-fixed');
else
$('.subnav').removeClass('subnav-fixed');
});
As of 2012-12-04 the accepted answer is no longer the best choise, since the desired functionality has been included into Bootstrap.
Please see Affix JavaScript component which is part of Bootstrap JS
Great Answer from #Oleg,
For people like me who want to reproduce the responsive behaviour of the .subnav
Here is the css code (without colors, borders and effects)
body { padding-top: 90px; }
#media (max-width: 980px) {
body {
padding-top: 0;
}
}
.subnav {
width: 100%;
}
#media (max-width: 768px) {
.subnav {
position: static;
top: auto;
z-index: auto;
width: auto;
height: auto;
}
.subnav .nav > li {
float: none;
}
}
#media (min-width: 980px) {
.subnav-fixed {
position: fixed;
top: 40px;
left: 0;
right: 0;
z-index: 1020;
}
.subnav-fixed .nav {
width: 938px;
margin: 0 auto;
}
}
#media (min-width: 1210px) {
.subnav-fixed .nav {
width: 1168px;
}
}

The two answers above work great, but I just thought I'd let people know that I've made this into a module (without the jQuery dependency) available at ForbesLindesay/booting-sub-nav. It can be used standalone with a script tag or via https://github.com/component/component/
Here is another code
$(function(){
var
$win = $(window),
$filter = $('.navbar'),
$filterSpacer = $('<div />', {
"class": "filter-drop-spacer",
"height": $filter.outerHeight()
});
$win.scroll(function(){
if(!$filter.hasClass('navbar-fixed-top')){
if($win.scrollTop() > $filter.offset().top){
$filter.before($filterSpacer);
$filter.addClass("navbar-fixed-top");
}
}else if ($filter.hasClass('navbar-fixed-top')){
if($win.scrollTop() < $filterSpacer.offset().top){
$filter.removeClass("navbar-fixed-top");
$filterSpacer.remove();
}
}
});
});
I am using Flot to graph some of my data and I was thinking it would be great to make this graph appear fullscreen (occupy full space on the monitor) upon clicking on a button. Currently, my div is as follows:
<div id="placeholder" style="width:800px;height:600px"></div>
Of course, the style attribute is only for testing. I will move this to CSS after during the actual design. Is there anyway I could make this div fullscreen and still preserve all event handling?
You can use HTML5 Fullscreen API for this (which is the most suitable way i think).
The fullscreen has to be triggered via a user event (click, keypress) otherwise it won't work.
Here is a button which makes the div fullscreen on click. And in fullscreen mode, the button click will exit fullscreen mode.
$('#toggle_fullscreen').on('click', function(){
// if already full screen; exit
// else go fullscreen
if (document.fullscreenElement) {
document.exitFullscreen();
} else {
$('#container').get(0).requestFullscreen();
}
});
#container{
border:1px solid red;
border-radius: .5em;
padding:10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
<p>
Toggle Fullscreen
</p>
I will be fullscreen, yay!
</div>
Please also note that Fullscreen API for Chrome does not work in non-secure pages. See https://sites.google.com/a/chromium.org/dev/Home/chromium-security/deprecating-powerful-features-on-insecure-origins for more details.
Another thing to note is the :fullscreen CSS selector. You can append this to any css selector so the that the rules will be applied when that element is fullscreen:
#container:fullscreen {
width: 100vw;
height: 100vh;
}
When you say "full-screen", do you mean like full-screen for the computer, or for taking up the entire space in the browser?
You can't force the user into full-screen F11; however, you can make your div full screen by using the following CSS
div {width: 100%; height: 100%;}
This will of course assume your div is child of the <body> tag. Otherwise, you'd need to add the following in addition to the above code.
div {position: absolute; top: 0; left: 0;}
CSS way:
#foo {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
JS way:
$(function() {
function abso() {
$('#foo').css({
position: 'absolute',
width: $(window).width(),
height: $(window).height()
});
}
$(window).resize(function() {
abso();
});
abso();
});
For fullscreen of browser rendering area there is a simple solution supported by all modern browsers.
div#placeholder {
height: 100vh;
}
The only notable exception is the Android below 4.3 - but ofc only in the system browser/webview element (Chrome works ok).
Browser support chart: http://caniuse.com/viewport-units
For fullscreen of monitor please use HTML5 Fullscreen API
.widget-HomePageSlider .slider-loader-hide {
position: fixed;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
z-index: 10000;
background: white;
}
Can use FullScreen API like this
function toggleFullscreen() {
let elem = document.querySelector('#demo-video');
if (!document.fullscreenElement) {
elem.requestFullscreen().catch(err => {
alert(`Error attempting to enable full-screen mode: ${err.message} (${err.name})`);
});
} else {
document.exitFullscreen();
}
}
Demo
const elem = document.querySelector('#park-pic');
elem.addEventListener("click", function(e) {
toggleFullScreen();
}, false);
function toggleFullScreen() {
if (!document.fullscreenElement) {
elem.requestFullscreen().catch(err => {
alert(`Error attempting to enable full-screen mode: ${err.message} (${err.name})`);
});
} else {
document.exitFullscreen();
}
}
#container{
border:1px solid #aaa;
padding:10px;
}
#park-pic {
width: 100%;
max-height: 70vh;
}
<div id="container">
<p>
Toggle Fullscreen
</p>
<img id="park-pic"
src="https://storage.coverr.co/posters/Skate-park"></video>
</div>
P.S: Using screenfull.js nowadays. A simple wrapper for cross-browser usage of the JavaScript Fullscreen API.
This is the simplest one.
#divid {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
u can try this..
<div id="placeholder" style="width:auto;height:auto"></div>
width and height depends on your flot or graph..
hope u want this...
or
By clicking, u can use this by jquery
$("#placeholder").css("width", $(window).width());
$("#placeholder").css("height", $(window).height());
Use document height if you want to show it beyond the visible area of browser(scrollable area).
CSS Portion
#foo {
position:absolute;
top:0;
left:0;
}
JQuery Portion
$(document).ready(function() {
$('#foo').css({
width: $(document).width(),
height: $(document).height()
});
});
<div id="placeholder" style="position:absolute; top:0; right:0; bottom:0; left:0;"></div>
With Bootstrap 5.0 this is incredibly easy now. Just toggle these classes on and off the full screen element.
w-100 h-100 position-absolute top-0 start-0 bg-white
