I am using Shopisle theme. I have displayed product category drop-down filter widget on the left side of shop page. But on the smaller screens, it automatically shifts at the bottom of the page. How can it be displayed on the top in smaller screens?
It can be done with some javascript on the window resize event. The sidebar is really on the right side in the HTML markup (Or more specifically, it's below). It appears on the left because css has the main section floating right.
On resize, css removed the float at width 767px. So the side bar falls to the bottom.
With jQuery's insertBefore (http://api.jquery.com/insertbefore/) as well as insertAfter, the html markup can be switched.
NB: this example moves the entire sidebar. It can be modified a bit to move just a single widget if that's necessary. This indicates the general process.
**By the way, this script should be placed in a .js file for the child-theme. If a .js file is not already in place, then try adding it to the footer template file (preferably in child theme) within <script>...</script> tags.
var sidebar_at_top = false;
function formatdisplay(){
if(jQuery( window ).width() < 768){
if(!sidebar_at_top){
console.log('moving sidebar to before main area');
jQuery('.sidebar-shop').insertBefore(jQuery('.shop-with-sidebar'));
sidebar_at_top = true;
}
}else{
if(sidebar_at_top){
console.log('moving sidebar to after main area');
jQuery('.sidebar-shop').insertAfter(jQuery('.shop-with-sidebar'));
sidebar_at_top = false;
}
}
}
jQuery( window ).resize(function() {
formatdisplay();
});
jQuery( document ).ready(function() {
formatdisplay();
});

I'm working with PrimeFaces and BootsFaces libraries. I have a little form inside bootsfaces modal. The form is used to change system parameters, and for one specific parameter has a <p:keyboard /> to change its value. My problem is that in extra-small devices, the bootstrap modal doesn't allow horizontal scroll, and the keyboard is not showing complete:
The keyboard is not responsive by default when the viewport with is less than 510px, so I have adjusted it to 436px by default in extra small screens. I want to make horizontal scroll on the modal just to see the complete keyboard, but only when I open the modal.
This is my javascript function to adjust the keyboard depending on screen size:
$(document).on('click', '.inpKeyboard', function() {//- The input text has a class called 'inpKeyboard'
if ($(window).width() <= 505) {//- Small screen
$('#keypad-div').css('width', '436px');
$('#keypad-div').css('left', '0px');
//$('.modal-open').css('overflow-x', 'auto');
}
$('#keypad-div').css('z-index', '2000');
});
Any help would be appreciated. Thanks.
What a nice puzzle! :) PrimeFaces calculate the size of the keypad window in JavaScript and stores it as an inline-style. So the clue to solving this is to add a timeout, like so:
<script>
$(document).on('click', '.hasKeypad', () => {
$('#keypad-div').css('z-index', '2000');
if (!(window.width > 505)) { // JSF (i.e. XML) doesn't accept the less-than-operator
// add a timeout to make sure the code is executed after PrimeFaces did its magic
setTimeout(() => {
// set a fixed with
$('#keypad-div').css('width', '436px');
// add the horizontal scrollbar
$('#keypad-div').css('overflow-x', 'auto');
// increase the height to make space for the scrollbar
$('#keypad-div').css('height', '180px');}
,1);
}
});
</script>
<!-- set a minimum width for the keyboard rows -->
<!-- (otherwise the key overflow to the next row) -->
<style>
#media screen and (max-width: 504px) {
.keypad-row {
min-width:470px;
}
}
</style>
Using w3css with a pinned navbar (ie enclosed in a with class w3-top) how can I know the height of the navbar (which will vary with screen size) so I can leave this much space at the top of my non-pinned content so the navbar doesn't overwrite content?
My best solution so far is to duplicate the navbar in javascript and insert that at the top of the page without the w3-top class so that there is a hidden element which is always the same size at the top of the page.
...
<div id="pinned_nav" class="w3-top">
<ul class="w3-navbar w3-light-grey w3-border">
<li>
...
<script type="text/javascript">
//Duplicate the nav without pinning it to the top - this means that the other content will adjust to height of pinned nav
var nav = document.getElementById("pinned_nav");
var nav_copy = nav.cloneNode(true);
nav_copy.classList.remove("w3-top");
nav.parentElement.insertBefore(nav_copy, nav);
</script>
...
Since this seemed less error prone than just copy and pasting the HTML block.
But it's still rather clunky and I just wondered if there was a simpler way I was missing.
Other questions like this one which are not w3css specific suggest using a fixed margin to skip a pinned toolbar but I can't see how to determine this margin height with a responsive navbar.
You could use a Javascript script to get the height and append it however you want to use it.
function getHeight() {
var nav = document.getElementById("pinned_nav");
var nav_height = nav.offsetHeight; //append this var where you need to.
alert(nav_height);
};
window.onload = getHeight();
window.onresize = getHeight(); //edit, added for if you resize the page
#pinned_nav {
height: 100px;
/*as example */
background-color: red;
}
<div id="pinned_nav" class="w3-top"></div>

Added resize event subscription.
In Firefox especially, I've run into an issue I can't figure out how to fix.
On the following page, when scrolling down the page jumps several times - mainly on smaller screens where the page doesn't have its full size displayed. You can replicate this issue by making your browser smaller than the page so you have to scroll.
It's on this page: http://www.nucanoe.com/frontier-accessories/
If I disable the position:fixed on the navigation selector, it fixes the issue - but we need the navigation to be sticky. Is there a solution to fix this? I'm thinking we may need to use jQuery somehow.
Thanks in advance!
After seeing you asking for help on another answer, I will try and explain more clearly for you.
The Problem
Your problem is when you add position:fixed to the navigation bar, it removes it from its place and sticks it at the top of the page. This is why the rest of your content jumps up - because the navigation bar is not where it was anymore.
How To Fix
You can get around this by wrapping your navigation element in a new div - let's call it nav-wrapper - and set its height to the same as your navigation element. These are known as placeholder elements. This new wrapper and your original navigation bar must always be the same height for the 'jump' to disappear.
<div class="nav-wrapper" style="height:80px;"> <-- add this
<div class="your-original-nav" style="height:80px"></div>
</div> <!-- add this
Now, when you set the navigation bar to fixed and it disappears to the top, the new wrapper we created with the same height keeps the page's content the same. When the fixed class has been removed, it sits back in the wrapper again, without pushing the content down.
A Suggestion
From what I can see on your site, there will be a big gap where the navigation bar was until the new fixed navigation reaches that point and covers it. What you want, is a little jQuery to figure out where to make the navigation fixed and where to hide it. I'll explain:
// cache the element
var $navBar = $('.your-original-nav');
// find original navigation bar position
var navPos = $navBar.offset().top;
// on scroll
$(window).scroll(function() {
// get scroll position from top of the page
var scrollPos = $(this).scrollTop();
// check if scroll position is >= the nav position
if (scrollPos >= navPos) {
$navBar.addClass('fixed');
} else {
$navBar.removeClass('fixed');
}
});
You may want to add further functionality to this example, as it is very, very basic. You would probably want to recalculate the offsets on window resize as one addition.
A Demo
This is a little demo which might help you - I was bored and feeling helpful :)
Made it this way now: Added an element before the nav:
<div class="nav-placeholder"></div>
And the jquery:
<script type="text/javascript">
$(document).on("scroll",function(){
if($(document).scrollTop()>150){
$(".nav-placeholder").height($(".nav").outerHeight());
} else {
$(".nav-placeholder").height(0);
}
});
</script>
When I scroll down to 150 the placeholder gets the height of the nav, when i scroll up again I set it's height to 0.
Here is a fiddle: https://jsfiddle.net/herrfischerhamburg/562wu62y/
You need to have a placeholder when your nav goes from relative to fixed.
Therefore you need to make a new div.
jQuery(".nav").wrap('<div class="nav-placeholder"></div>');
jQuery(".nav-placeholder").height(jQuery(".nav").outerHeight());
jQuery(".nav").wrapInner('<div class="nav-inner"></div>');
Remember to change ".nav", "nav-inner" and "nav-placeholder" to your desire.

I solved the problem differently so on firefox as you can see in logs it scroll up itself so to stop this scrolling I made simple statement
$(document).ready(function () {
var header = $('#left-menu');
var offset = header.offset().top;
var up = true;
$(window).scroll(function () {
var scroll = $(window).scrollTop();
console.log(scroll + ' ' + offset )
if (scroll >= offset) {
header.addClass('sidebar-sticky');
if (up){
$(window).scrollTop(offset);
up=false;
}
} else {
up=true;
header.removeClass('sidebar-sticky');
}
});
});
that solution work for me when I can't specify height of div's I use.
my website sidebar widgets look fine when I view www.aryaziai.com from my desktop. However, The ONLY issue I have is that when I view my mobile version of my site, the "featured video" sidebar sticks out of the frame and overlaps a bit with the black background.
At the end of the day I don't want to manually change the width/height of the youtube video, I just want the width of the "featured video" widget to automatically resize to the size of widget title (the blue block thing).. Its interesting because the size of the youtube video is the same as the widget title when viewing on a desktop, but the widget title remains at a perfect size in the mobile..
Any 100% width codes out there that can fix this? Thanks
If I understand correctly, you're having a problem getting your YouTube video to adjust to the screen width even if the div you're wrapping it in is correctly resized. If so, please read Chris Coyier's article on resizing YouTube videos.
You can do all of this in jQuery (if you're using it), here's Chris' code:
$(function() {
// Find all YouTube videos
var $allVideos = $("iframe[src^='http://www.youtube.com']"),
// The element that is fluid width
$fluidEl = $("body");
// Figure out and save aspect ratio for each video
$allVideos.each(function() {
$(this)
.data('aspectRatio', this.height / this.width)
// and remove the hard coded width/height
.removeAttr('height')
.removeAttr('width');
});
// When the window is resized
// (You'll probably want to debounce this)
$(window).resize(function() {
var newWidth = $fluidEl.width();
// Resize all videos according to their own aspect ratio
$allVideos.each(function() {
var $el = $(this);
$el
.width(newWidth)
.height(newWidth * $el.data('aspectRatio'));
});
// Kick off one resize to fix all videos on page load
}).resize();
});
Here's the scenario:
I have an asp.net webpage which displays dynamic data in a gridview.
I'm using a master page to display the header and footer of the page, and this gridview is being displayed inside a div in the contentplaceholder.
The Problem:
What I want is that the size of the page that is displayed remains constant for a user and must be equal to the size of their browser's available display area and the content being visible by scrolling the div.
Sort of like the header and footer remain at the same position and the content inside it is scrollable.
I really don't know how to achieve this.
Any help on the matter is highly appreciated.
Thanks.
Try some jQuery:
function changeHeight(){
var winHeight = $(window).height();
var heightOfHeaderAndFooter = 200px; // change this to what you need
$('#myDiv').height($(window).height() - heightOfHeaderAndFooter);
}
$(window).resize(function() { // changes height with browser window
changeHeight();
});
$(document).ready(function() { // changes height on load of the page
changeHeight();
});
What you want is for your div to use width:auto and to dynamically change the height of it to always keep the footer at the bottom of the page. Also, make sure your div has overflow-y:scroll
Code snippet:
divMain.style.height --> height of div in pixel containing GridView. This div tag also has style setting of style="overflow-y:auto;"
document.documentElement.clientHeight --> height of the working/client area for your display.
document.getElementById("divMain").offsetTop --> height of content prior to divMain.
25 --> this is the height of my additional footer.
The pixel result is the height available for your divMain.
divMain.style.height = (document.documentElement.clientHeight - document.getElementById("divMain").offsetTop - 25) + "px";
Hope this helps.
