I am having some scrolling issue when using my website on mobile devices (tested on iPhone).
The issue is that, on mobile, when touching or moving finger outside of the scrollable div, when trying to scroll this div after that, it is blocked until you wait a moment or scroll slowly, or touch it.
https://imgflip.com/gif/75nefo shows my issue. when scroll outside 'scrollable', then when scrolling back into scrollable, it keeps scrolling the whole body and takes a few more tries until it finally scrolls where I want.
The website is the following, as seen in the gif.
body{
margin: 0;
padding: 0;
}
.frame{
display: flex;
flex-direction: column;
width: 100%;
height: 100vh;
background-color: lightblue;
overflow: hidden;
}
.scrollable{
overflow: scroll;
}
.bottom-nav{
width: 100%;
background-color: lightcoral;
padding: 30px 10px;
box-sizing: border-box;
}
.sample-cube{
background-color: lightgreen;
box-sizing: border-box;
padding: 10px;
width: 100%;
height: 200px;
}
.sample-cube + .sample-cube{
margin-top: 10px;
}
<body>
<div class="frame">
<div class="scrollable">
<div class="sample-cube"> this is stuff on the scrollable area</div>
<div class="sample-cube"> </div>
<div class="sample-cube"> </div>
<div class="sample-cube"> </div>
<div class="sample-cube"> </div>
<div class="sample-cube"> </div>
<div class="sample-cube"> </div>
</div>
<div class="bottom-nav">
navigation area with options
</div>
</div>
</body>
I was wondering if there's any way to give the scrollable div a priority so that, whenever it is scrolled on, it scrolls from the first finger touch-swipe instead of being locked...
Ended up finding something that works for me, after doing some investigation, the issue seems to be related to how IOS Safari handles scrolling. This question has many approaches as answers but there's one in particular that works the best for me.
There's this library that lets you block the body scroll, when you want a fixed body like on my case, and allow scroll only on a certain element. It works like a charm!!!
Body Scroll Lock on npmjs
Now my scroll doesn't 'freeze' when I scroll outside of my scrollable element and quickly scroll my scrollable element again!!

In chrome it can work well

This issue only happen when container height is less than fex items and set overflow-y:auto/scroll.
Is anyone can help me find the cause of the issue?
Appreciate for your help.
Internet Explorer needs you to specify the flex value of you children.
Try to add the property flex: 1 0 auto; to the FlexItem class
I've found the key point maybe the format of setting the width of FlexItem.
If you change the width:80% as 200px, it will work well in IE.
I guess that if you write in % format, IE may could not understand it well.
So you should give a static length to it.
So My situation is this, I have a lot of divs... A LOT (over 300) and im using them as part of an interactive background. EDIT:(they all have the same class btw)
The Problem?
Since on mobile I need more divs to fill the page than on desktop, I have too many divs on desktop, meaning you can scroll wayyyyyy more than I want to.
How can I have it so Divs Below a certain point are deleted or (more usefully) how to stop scrolling after a certain amount of pixels.
I literally have no idea how to do this, I've tried experimenting with margins, padding, overflow, position: fixed; but I haven't found a solution so don't pester my "lack of effort"
(some of my accounts have been blocked because I had no legitimate idea what to do and you "cool kids" decided to downvote me enough to get blocked (thanks for that!))
Anyway enough blabbing. Help would be appreciated! Thanks in advance.
You can do 2 things for this:
Wrap all your content in a div and set height to it and overflow-y: hidden.
.wrapper{
height: 1000px; overflow-y: hidden
}
With CSS you can hide the elements after certain number. Like if you want to hide all div after 100
.container .className:nth-child(n+101) {
display: none;
}
This will hide all the divs after 100.
Put all your divs inside a container div and use this css
.container{
max-height:900px; // Set this value to the no of pixel you want to scroll
overflow:hidden;
}
I have set the max-height to 900px cause i want to show only 9 div each div is off height 100px.
SNIPPET
.item {
width: 100%;
height: 100px;
background-color: red;
}
.item:hover {
background-color: yellow;
}
.container {
max-height: 900px;
overflow: hidden;
}
<div class="container">
<div class="item">1</div>
<div class="item">2</div>
<div class="item">3</div>
<div class="item">4</div>
<div class="item">5</div>
<div class="item">6</div>
<div class="item">7</div>
<div class="item">8</div>
<div class="item">9</div>
<!--You cant scroll after that-->
<div class="item">10</div>
<div class="item">11</div>
<div class="item">12</div>
<div class="item">13</div>
<div class="item">14</div>
</div>
I need some help setting up a column-based grid for flexible layout. I am hoping to use flexbox primarily, but have been unable to figure out how to implement exactly what I need. I am also open to using a JS grid plugin, but again have not found one that meets me specific needs.
Here is a photo that illustrates what I'm hoping to build.
Grid Illustration
The most important priorities are:
The layout creates as many columns as possible within the master content container.
After organizing the content blocks in columns, resize each content block so that each column's height is uniform.
The height of the master content container's height scales fit content within.
Having the elements display in order is preferable, but not mandatory.
I also want the width of the content container to scale based on device. So predictably when it goes down to mobile it becomes a simple one column layout.
Now I believe I can control the number of grids by setting the container width, and content block width specifically based on device. I.e. if it's on mobile the content blocks are 100% width, and if it is on desktop the container is 900px and the content blocks are 300px.
That plus flexbox should give me something that resembles this. Flexbox Illustration, but only if I set a fixed height on the master container, which is not ideal.
So my question is, is there a way to setup flexbox to achieve my goals? If, not is there JS plugin that is capable of doing this?

CodePen
I'm trying to get a navigation div to sit in the middle between an image and the right page but also in a way that if the browser is resized, will still maintain the relation. I'm quite positive I know how to do it with a relative positioning but I would like to have the navigation fixed.
[img] nav |right side of viewport
#wrapperNav {
position: fixed;
top: 45%;
right: 50%;
z-index:999;
}
Code: http://jsfiddle.net/LLtnZ/3/
Flexbox has support in most newer desktop and mobile browsers and really dispenses with a lot of the hackiness involved in trying to maintain alignment and positioning with varying screen sizes; it flexes.
For the carousel you describe I would start with the below HTML, based on what you provided in your fiddle:
<div id="wrapper">
<nav class="nav nav--ready">
<div class='nav__center'>
<div class="nav__link nav__link--active">
<a class="nav__link-bullet" href="#one">1</a>
</div>
<div class="nav__link">
<a class="nav__link-bullet" href="#two">2</a>
</div>
<div class="nav__link">
<a class="nav__link-bullet" href="#three">3</a>
</div>
<div class="nav__link">
<a class="nav__link-bullet" href="#four">4</a>
</div>
<div class="nav__link">
<a class="nav__link-bullet" href="#five">5</a>
</div>
</div>
</nav>
<div class='carousel'>
<img src="" alt=""/>
</div>
</div>
#wrapper is a flexbox, .nav is too, so is .nav__center. #wrapper is set to flex-direction: row-reverse; so as to display navigation on the right, if we added another element to #wrapper it would display to the right of .nav. .nav itself is set to flex-direction: row;, though it only has one child: .nav__center, its flexbox styles of justify-content: space-around; and align-items: center; keep the nav buttons aligned at its center no matter what. Within .nav, .nav__center is set to flex-direction: column; so its contents display top to bottom, and these styles align-self: stretch; justify-content: space-around; distribute each .nav__link element evenly from top to bottom.
Here is a fiddle. Notice that navigation stays glued to the right side of the carousel. I set a minimum width on .nav so that it won't disappear even when the display is really tiny.
Here is a quick guide you can probably get through in ten minutes with a cup of coffee.
You need to add position: relative; to your container which in this case is the nav html element.
http://jsfiddle.net/LLtnZ/4/
This might help. So if your image is is 90% width and centered, that will leave 10% left of pagespace, 5% on either side of the image.
If I understand your drawing correctly, the that would mean you'd want the container your nav is in to be
width: 5%
position:fixed;
top: 50%;
right:0;
margin-top -150px; // half the height
height: 300px;
text-align:center;
The 5% width will take up the entire space to the right, but using text-align:center will get items in the middle, as per your "equal" annotation on your drawing.
If you need a jsFiddle let me know
Here's a fiddle: http://jsfiddle.net/47Q9p/
I am using a jQuery slider panel that pushes the content down rather than overlap it (intended), which works fine on Chrome but not Firefox. On Firefox, it pushes the content down, but when I close it, the pushed down contents stay put, thus leaving a gap where the panel used to be.
How exactly do I go about fixing this? Here's the code I used for the panel:
<div id="about">
<div id="panel">
<!-- the content -->
</div> <!-- end #panel -->
<p id="top" class="slide">+ about</p>
</div> <!-- end #about -->
This is the Javascript:
$(".btn-slide").click(function(){
$("#panel").slideToggle("slow");
$(this).toggleClass("active"); return false;
});
Thank you for your help. :)
Modify the panel style to include float:left and width:100%
#panel{
background-color: black;
display: none;
float: left;
height: 250px;
padding: 50px 0 20px;
width: 100%;
}
This should fix your problem.
