sticky div in page header overlapping page content

sticky div in page header overlapping page content - javascript

I have a "sticky" div that starts in an absolute position and then switches to fixed at top: 0 once the window begins to scroll (I am using it as a navigation bar), but I also have "in-page" links.
My problem is that the sticky overlaps the other content in the body, in other words the top 200px (the size of the navbar) become hidden (beneath the sticky navbar) as soon as they begin to scroll down.
Is this a CSS problem or a JavaScript problem? How can I fix it?
http://jsfiddle.net/b26g1ztu/
javascript:
function sticky_relocate() {
var window_top = $(window).scrollTop();
var div_top = $('#sticky-anchor').offset().top;
if (window_top > div_top) {
$('#sticky').addClass('stick');
} else {
$('#sticky').removeClass('stick');
}
}
$(function () {
$(window).scroll(sticky_relocate);
sticky_relocate();
});

I think your problem is a bit JS and a bit CSS.
You're using JS/JQuery to toggle between two CSS classes and essentially toggling between absolute and fixed positioning. Further you are using top to make your decisions in JS, but they evaluate to different values when you are in absolute or fixed positioning.
Finally, i'd recommend that you either (a) just stick with fixed positioning and adjust the location (top/left) onscroll or (b) when you are in .stick mode add padding-top:300px to the body or margin-top:300px on body section:first-child

How to prevent page scroll to the top while menu opened

There is a menu button on the page. When a user taps the button full-page menu opens. There is a problem - the main content page automatically scrolls to the top. Could you advise me on how to prevent it? I've already checked a similar question here How to disable scrolling in the background when the mobile menu is open?, but nor position:fixed or oveflow:hidden helped
const menuOpen = document.querySelector('.menu-open');
const menuClose = document.querySelector('.menu-close');
const body = document.querySelector('.root');
function lockScroll() {
body.classList.add('lock');
}
function unLockScroll() {
body.classList.remove('lock');
}
menuOpen.addEventListener('click', lockScroll);
menuClose.addEventListener('click', unLockScroll);
.lock {
position: fixed;
height: 100vh;
overflow-y: hidden;
}
.menu-open {
position: fixed;
top: 0;
right: 0;
cursor: pointer;
transition: all ease 0.6s;
border: 0;
background: none;
padding: 1rem 1rem 2rem 2rem;
}
.nav-container {
position: absolute;
left: -100%;
width: 100%;
height: 100vh;
background: #f5f5f1;
z-index: 5;
}
<header class="header">
<button type="button" class="menu-open"><img src="./images/menu.svg" alt=""></button>

doesn't help.

I think your main body elements are positioned static (or relative if defined?), untill you change it by overriding with position fixed.
A better behaviour would be to leave your nav container be positioned absolute on "menuOpen" and leave the remainder of elements in their already defined flow so your full screen simply overlay's the rest of the elements.

Click in a button overwritten by an image

In my HTML website I have a button, and I try add an transparent image over this button. And I can't click in this button after.
My problem is something like this:
#container {
height: 400px;
width: 400px;
position: relative;
}
#image {
position: absolute;
left: 0;
top: 0;
}
<div id="container">
<img id="image" src="http://upload.wikimedia.org/wikipedia/en/2/2d/SRU-Logo-Transparent.png" width="200px" ;height="200px" />
<a href="#">
Click here
</a>
</div>
Thanks very much for your help!

To fix this you can set the z-index of the image lower than the a element (which defaults to 0)
#container {
height: 400px;
width: 400px;
position: relative;
}
#image {
position: absolute;
left: 0;
top: 0;
z-index: -1;
}
<div id="container">
<img id="image" src="http://upload.wikimedia.org/wikipedia/en/2/2d/SRU-Logo-Transparent.png" width="200px" ;height="200px" />
<a href="#">
Click here
</a>
</div>
Alternatively you could use the image as a background on the container and avoid the need to position it absolutely, or have to change z-index at all.

you need to add a z-index to the button and give it position relative
.button {
z-index: 1;
position: relative;
}
Here is the code you need to use
html
<div id="container">
<img id="image" src="http://upload.wikimedia.org/wikipedia/en/2/2d/SRU-Logo-Transparent.png" width="200px";height="200px"/>
<a class="button" href="#">
Click here
</a>
css
#container
{
height:400px;
width:400px;
position:relative;
}
#image
{
position:absolute;
left:0;
top:0;
}
.button {
z-index: 10;
position: relative;
}
See js fiddle here

You can alter width and height of image-container as you wish..
#container {
height: 400px;
width: 400px;
position: relative;
}
#image-container{
width:100%;
height:100%;
background-image: url("http://upload.wikimedia.org/wikipedia/en/2/2d/SRU-Logo-Transparent.png");
background-position:center;
background-size:contain;
}

Make footer stay at bottom of page (not fixed to bottom)

I am trying to make just the pages on my website that have the main body content class of ".interior-health-main" have a footer that is static at the bottom of the page. I want it at the absolute bottom, currently if you view some of my pages on a large screen, you will see a bunch of white space after the footer. I want to get rid of this.
I have been looking into this for hours now and tried many things, at first I was going to make the footer on the entire website static at the bottom of the page, but setting the footer's css to position: absolute conflicted with other elements on my home page, which is why I just want it on the ".interior-health-main." If it is possible to change it just for the footers on these pages please let me know, I do not really want examples of fixing this by setting the entire body to position:relative. It just messes up my homepage.
Here is an example of what it looks like with the white space after the footer http://codepen.io/aahmed2/full/KgWNYL/
<p class="nav">This is a Navigation Bar</p>
<div class="interior-health-main">

Here is my css
.nav {
text-align: center;
padding: 25px 0;
background-color: #c1c0be;
color: #fff;
position: fixed;
width: 100%;
z-index: 2;
}
.interior-health-main {
padding-top: 80px;
padding-bottom: 20px;
}
#media (max-width: 479px) {
.interior-health-main {
padding-top: 50px;
}
}
.footer {
background: #333332;
border-top: 9px solid #ffffff;
color: #fff;
padding-top: 35px;
padding-bottom: 35px;
}

You can position the footer absolute like they did here
https://getbootstrap.com/examples/sticky-footer/
.footer {
position: absolute;
bottom: 0;
width: 100%;
/* Set the fixed height of the footer here */
height: 60px;
/* background-color: #f5f5f5; */
}
<footer class="footer">
<div class="container">
<p class="text-muted">Place sticky footer content here.</p>
</div>
</footer>
How did it conflict when you tried your way? update your post with what you did?

Please reference this question to find your solution.
I applied one of the solutions from the above link to your code.
Wrap your code in a #holder div.
Add the following CSS:
html,body{
height: 100%
}
#holder{
min-height: 100%;
position:relative;
}
.footer {
background: #333332;
border-top: 9px solid #ffffff;
color: #fff;
padding-top: 35px;
padding-bottom: 35px;
height: 300px;
width:100%;
position: absolute;
left: 0;
bottom: 0;
}
.interior-health-main {
padding-top: 80px;
padding-bottom: 300px; /* height of footer */
}
Here is the working fiddle:
https://jsfiddle.net/DTcHh/25475/

I wrapped your page (not containing footer) into .page-wrap div, and edit you codePen code and just add this piece of code to your css
html, body {
height: 100%;
}
.page-wrap {
min-height: 100%;
/* equal to footer height (with margin and border) */
margin-bottom: -299px ;
}
.page-wrap:after {
content: "";
display: block;
}
.footer, .page-wrap:after {
/* page-wrap after content must be the same height as footer */
height: 299px;
}

playing fadein/fadeout slider on tab button click

I have created a Fadein/Fadeout slider. Left button and right button are working fine but I want to play slider by clicking on tab buttons.

$(".icon-s2").click(function() {
activeElem = $("#target .slide-02");
activeElem.removeClass('active').fadeOut(0);
if (!activeElem.is(':first-child')) {
activeElem.removeClass('active').fadeOut(0).prev().addClass('active').fadeIn(400);

activeElem.removeClass('active').fadeOut(0);
if (!activeElem.is(':first-child')) {
activeElem.removeClass('active').fadeOut(0).prev().addClass('active').fadeIn(400);
}
}
When I press the tab it does not work to try to appear a DIV.

Your code made no sense. The way it looked was that the images had to be clicked in order to fadeIn/Out the tabs. I believe it should be the other way. I cleaned up the markup, and simplified the classes, ids, styles, etc...
Here's the DEMO
HTML
<div id="slides">
<div id="slide1" class="slide active">

</div>
<div class="tab-area" id="controls">
<div id="tab1" class="tab">1</div>
<div id="tab2" class="tab">2</div>
<div id="tab3" class="tab">3</div>
<div id="tab4" class="tab">4</div>
</div>
CSS
.slide {
display:none;
}
.active {
display: block;
}
.tab {
width: 16px;
height: 16px;
display: inline-block;
margin: 0 10px;
outline: 1px solid black;
text-align: center;
cursor: pointer;
}
jQuery/JavaScript
$(function () {
$('.tab').on('click', function (event) {
var tabID = event.target.id;
//console.log('tabID: '+tabID);
var order = tabID.split('b').pop();
//console.log('order: '+order);
var pos = parseInt(order, 10);
var slideID = 'slide'+pos;
//console.log('slideID: '+slideID);

Sidebar fixed panel with fixed content block

I have a sidebar which is position:fixed; and overflow:auto; - this causes the scroll to happen within the fixed element.
Now when the sidebar is turned on, that element does not move, its just static on the page.
What i want to achieve: I would like to fix .super-image-thumb inside the scroll element, so when the scroll happens, the thumbnails at the top are fixed.
I have tried a javascript fix as well but its still not working. Any recommendations?
jQuery(function($) {
function fixDiv() {
var $cache = $('.super-image-thumb');
if ($('.sliding-panel-content').scrollTop() > 100)
$cache.css({
'position': 'fixed',
'top': '10px'
});
else
$cache.css({
'position': 'relative',
'top': 'auto'
});
}
$('.sliding-panel-content').scroll(fixDiv);
fixDiv();
});
.sliding-panel-content {
z-index: 1204;
}
.middle-content {
border-left: 1px solid #ddd;
border-right: 1px solid #ddd;
}
.middle-content {
position: fixed;
left: 8%;
top: auto;
width: 85%;
-webkit-transform: translateY(-115%);
-ms-transform: translateY(-115%);
transform: translateY(-115%);
transition: all .25s linear;
}
.sliding-panel-content {
overflow: auto;
top: 0;
bottom: 0;
height: 100%;
background-color: #fff;
-webkit-overflow-scrolling: touch;
}
.sliding-panel-content.is-visible {
-webkit-transform: translateX(0);

transform: translateX(0);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<button name="prev" id="super-prev">Prev</button>
<button name="next" id="super-next">Next</button>
</div>
</div>
</div>

Fixed inside Fixed is always buggy. Let's just change top: http://jsfiddle.net/s31edgao/
function fixDiv() {
$('.super-image-thumb').css({
'top': $('.sliding-panel-content').scrollTop()+'px'
});
}
$('.sliding-panel-content').scroll(fixDiv);
fixDiv();

Javascript for that will only make the things more complicated.
It is all about CSS, the position: fixed or absolute is always based on the first ancestor with position: relative, so you should play with it.
I would remove the jQuery code and add this CSS:
.slide-content {
position:relative;
}
.super-image-thumb {
position:fixed;
background: #FFF;
top:0;
width:100%;
z-index: 2;
}
.main-image-container {
position:absolute;
top:85px;
z-index: 0;
}
As in the jsfiddle

It looks like transitions and position: fixed does not work together in all browser, when you remove them, code works fine. Some solution for this you can find in css3 transform reverts position: fixed
I created snippet without transitions and also I removed JS part (I think is not needed), and propose CSS-only solution. It is not finished to the end, it needs some more aligments - but you can do it yourself - the way for solving your problem is clear, I think.
