I have a problem with slider controls and any block with position: absolute on slider section.
$(document).ready(function() {
$('#fullpage').fullpage();
});
.slide {
text-align: center
}
.section {
text-align: center;
}
.absolute {
position: absolute;
top: 0;
left: 0;
right: 0;
height: 50px;
text-align: center;
background: red;
z-index: 2;
}
.slide1 {
background: #cccccc;
}
.slide2 {
background: #C3C3C3;
}
.section2 {
background: green;
}

<div class="section section2">Some section</div>
</div>
If you slide down and up - everything is ok. But if you use slider and then will slide down and up. The page will show without slider controls(and absolute block).
I can't find why it is happening. Problems occurs only in Chrome and Opera.
UPDATES:
Here is jsfiddle for example: https://jsfiddle.net/nfL5w9yL/1/
Fullpage adds z-index:1 to fp-slides
Had the same issue recently, i don't know if you found a solution, but my solution was to remove z-index from fp-slides!
the weird part is that in my case the navigation buttons were not affected, only my position absolute div

In the background of my slider, an image with negative z-index is placed. That way, the image can contain alt-text and have the effect of a fixed background-image.
At first glance, this works fine, but during the transition to the new slide, the z-index of the background-image seems to be overwritten and is displayed on top of everything else. How can I solve this?
const banner = document.getElementsByClassName("banner");
let activebanner = 0;
setInterval(changebanner, 8000);
function changebanner() {
banner[activebanner].classList.remove("active");
activebanner++;
if (activebanner === banner.length) {
activebanner = 0;
}
banner[activebanner].classList.add("active");
}
.slider {
width: 100%;
position: relative;
height: 600px;
}
.banner {
overflow: hidden;
display: flex;
align-items: center;
justify-content: center;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
visibility: hidden;
opacity: 0;
transition-duration: 1s;
}
.banner.active {
visibility: visible;
opacity: 1;
}
.banner-image {
position: fixed;
top: 0;
left: 0;
object-fit: cover;
width: 100%;
height: 620px;
z-index: -2;
}
.image-credits {
position: absolute;
bottom: 0;
right: 0;
}
<div class="slider">
<div class="banner active">
<img class="banner-image" src="path-to/image.jpg" alt="A background-image.">
<div class="content">
<h1>A clever Tagline</h1>
</div>
</div>
<div class="banner">
<img class="banner-image" src="path-to/image.jpg" alt="A background-image.">
<div class="content">
<h1>A clever Tagline</h1>
<p class="image-credits">Image by Photographer</p>
</div>
</div>
<div class="banner">
<img class="banner-image" src="path-to/image.jpg" alt="A background-image.">
<div class="content">
<h1>A clever Tagline</h1>
</div>
</div>
</div>
I set the overflow state of the whole slider and of the banner to hidden. That did not work. Another solution was to give the whole slider a negative z-index. But then, the link on the image-credit isn't clickable anymore, because the slider is behind the website body. Searching online for this specific problem did not get me any useful results. I only find solutions and other questions about how to animate the z-index.
In col-2, I am trying to center the "WHAT" text over the image.
<div class="row">
<div class="col-2">
<div class="stackParent">
<img class="stack-Img" src="img/base.png">
<div class="stack-Txt">
<div class="fourWsText stack-Txt-child">WHAT</div>
</div>
</div>
</div>
<div class="col-10">
...Variable length content...
</div>
</div>
As we resize the browser, the row height will change so that everything in col-10 fits. I am using object-fit:contain to keep the image proportions correct. I need the "stack-Txt" div to resize with the image so that the text will stay centered over the image
Or maybe you know of a better way to achieve this?
Current Idea:
Put WHAT in another child div, make flex, center text with justify-content/align-items
&
JS addEventListener to window resize, get the img div and set nextSibling size equal to this.
These were the css classes at some point... but the only important thing is that the img doesn't overflow the col-2 or the height (which is variable based on the length of col-10)
.stackParent {
position: relative;
object-fit: contain;
max-width: inherit;
height: 20vh;
}
.stack-Txt {
position: absolute;
text-align: center;
width: 100%;
max-height: 15vh;
min-height: 15vh;
z-index: 4;
}
.stack-Txt-child {
}
.stack-Img {
position: absolute;
object-fit: contain;
max-width: inherit;
min-height: 15vh;
max-height: 15vh;
top: 0%;
left: 0%;
z-index: 3;
}
*Note: I also have media queries to resize text, but this shouldn't make a difference.
If you are using Bootstrap 5 you can just use the built-in classes to achieve so.
Apply .position-relative to the main div parent
Apply .img-fluid to <img /> to make image responsive
Apply .position-absolute, .top-50, .start-50, translate-middle to stack-Txt to center it vertically and horizontally over the image.

If you don't, just edit your CSS as follow:

.stack-Img {

.stack-Txt {

I have been reading about fixed div's within relative and absolute div's here:
Fix position of div with respect to another div
Fixed positioned div within a relative parent div
Fixed position but relative to container
And many other but none can help me to achive a behavior I have seen in few pages (blogs). I can not remember one at the moment, but here are some images to explain
View 1 & View 2
After scrolling down, the contextual menu sticks to the side of the view and moves down with the scrolling until reach the end of the section in which it stops. If there is more content after it, you can keep scrolling down but the contextual menu no longer follow your view. The same going up, you reach the section, the contextual menu follows you up until the start of the section, then stops and you can keep scrolling up.
Is this posible with only HTML and CSS or do I need a plugin?
Here is a jsFiddle piece of code, perphaps incomplete. Forgot to mention, I'm doing this in Angular 6+ as a component, so I don't have full access to the index.html file with the body tag. The jsFiddle shows what I can work with.
There were a few things going on:
You can set body { position: relative } in your CSS
position: sticky needs a full height column to work. Because your col-6 that was holding your menu was only as tall as it needed to be, it won't scroll.
I moved the p-sticky class to your column.
sticky also needs a top value to know where the element should stick to once it becomes sticky.
.p-sticky {
position: sticky;
top: 60px;
}
body {
position: relative;
}
/*some attemps*/
.p-relative {
position: relative;
}
.p-absolute {
position: absolute;
}
.p-sticky {
position: sticky;
top: 60px;
}
.p-fixed {
position: fixed;
}
/* Standar CSS*/
.navbar {
background-color: blue;
width: 100%;
}
.nav-fixed {
top: 0px;
z-index: 1;
position: fixed;
}
.content-ex1 {
height: 200px;
background-color: green;
}
.content-ex2 {
height: 500px;
background-color: #aaaaaa;
}
.menu {
height: 50px;
background-color: red;
}
<div class="navbar">

</div>
<div class="navbar nav-fixed">

</div>
<div class="content-ex1"> Some content here</div>
<div class="container">
<div class="row">
<div class="col-sm-6 p-sticky">
<div class="menu">menu or something</div>
</div>
<div class="col-sm-6 content-ex2"> Some content here</div>

<div class="content-ex1"> Some content here</div>
Here's the fiddle to play around with (which includes your bootstrap):
http://jsfiddle.net/w4mz9dte/
Note: you appear to be using an old version of BootStrap. You may want to update to the newest version. In that case, only a few things will change - namely, you move the p-sticky class to the menu.
Here's the newest version of BS 4.4: http://jsfiddle.net/kamr0bjw/
body {
position: relative;
}
/*some attemps*/
.p-relative{

.p-absolute{

So I'm trying to animate a sidebar sliding in from the left, and the animation works well but it makes the other element, which uses flex for sizing, jumpy while it automatically resizes. This is what it looks like:
Here's some of my CSS:
body{
display: flex;
}
#sidebar{
display: none;
float: left;
height: 100%;
position: relative;
padding-left: 20px;
padding-right: 20px;
}
#mainScreen{
float: right;
height: 100%;
flex-grow: 1;
display: flex;
flex-direction: column;
}
And here's my basic HTML structure:
<body>
<div id="sidebar>
<!-- stuff -->
</div>
<div id="mainScreen">
<div id="headerCont"><!-- stuff --></div>
<div id="messageCont"><!-- stuff --></div>
<div id="chatInputCont"><!-- stuff --></div>
</div>
</body>
And the children of #mainScreen have another flex arrangement, but vertically. In Javascript I'm using $("#sidebar").toggle("slide", { direction: "left" }, 1000); when you click the menu button and it nearly works but I just want to eliminate the jumpiness. Does any know how to fix this, or if there are any alternative approaches I haven't thought of?
Its actually float creating problem, Its better restructure your HTML if Possible something like this.
<body>
<div class="main-content>
<div class="left-section">
<div id="sidebar>
<!-- stuff -->
</div>
</div>
<div class="right-section">
<div id="mainScreen">
<div id="headerCont"><!-- stuff --></div>
<div id="messageCont"><!-- stuff --></div>
<div id="chatInputCont"><!-- stuff --></div>
</div>
</div>
</div>
</body>
Now remove float and use flex on .main-content.
css
.left-section {
position: absolute;
top: 0;
bottom: 0;
left: -100%;
}
.left-section.slide {
left: 0;
}
.main-content.slide {
margin-left: 188px; // left-sidebar width
}
function sidebarClick(){
$(".left-section, .main-content").toggleClass("slide");
}
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">
<div class="container">
<ol class="breadcrumb">

</ol>

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;
}
