I'm building an application and on mobile we have a panel that slides in and takes up 100% of the viewport. This is has the position:fixed attribute attached to it. At the top of the panel I have a "back to" link, which is a <p> with an anchor <a>Back to...</a> inside it.
Now what I'm trying to achieve is to affix this to the top of the page so that when the user scrolls down the page the "back to" link is always at the top of the page. The reason for this is that the panels can often contain a lot of information, especially on mobile. I do not want to use Javascript as I'm hoping there is a way around this with CSS.
I've tried giving this <p> a position:fixed attribute but as it's containing block is positioned fixed it doesn't do anything! Is there a way around this issue? Has anyone done something similar before ?
HTML
<div id="panelDiv">
<p>Back to...</p>
......
Panel content goes here
......
</div>
CSS
#myDiv {
bottom: 0;
left: 0;
overflow: scroll;
padding: 0.85714em;
position: fixed;
right: 0;
top: 0;
transform: translateX(-100%);
transition: transform 350ms ease-in 0s, opacity 350ms ease-in 0s;
z-index: 9999;
}
p {
position:fixed;
top:0;
}
Now, what I think is happening is that because the container is already fixed, the browser already keeps the container fixed to the top and therefore when I add the same to the containing element it doesn't do anything. Is there a way around this?

Heyy.
I've been trying to figure this out and I've looked all over but so far nothing's worked so I thought maybe you could help me out.
I'm working on a new tumblr theme with masonry and I want the post captions to slide down when a post is hovered on. I got that bit working but the problem is the post underneath the one hovered won't be pushed down when the caption opens, and that means that bigger captions will be hidden behind that post.
Here's the code I have:
.c220 {
max-height: 0;
transition: max-height 1s ease-out;
overflow: hidden;
background: white;
}
.p200:hover .c220 {
max-height: 500px;
transition: max-height 1s ease-in;
}
And here's the link to see it live: https://thm-maddison.tumblr.com/
The captions I have aren't too big so they don't get hidden but I'd like the post below them to be pushed down about 60px if that's possible.
Thank you for your help and I wish you all a great 2017!
You need to do this without applying position: absolute; to the <article class="p200... elements. Absolutely positioned elements are outside of the html element flow.
I use google fonts to show some h1 tag. Initially, this h1 tag is hidden using:
visibility: hidden;
opacity: 0
I then slowly reveal the text when you hover over it with the following:
.content:hover{
visibility: visible;
opacity: 1;
transition: opacity ease-in-out 1s;
}
See here for demo: http://codepen.io/gosusheep/pen/oXEyve
Whenever the content becomes fully visible, it jumps a bit.
This jumping does not happen when the content is already visible.
This content does happen with other non-websafe fonts (e.g. Georgia).
Does anyone know a way around this?
After adding a margin: 20px, everything works as expected. I was able to keep the transform as well.
What I believe is happening is that the font requires more space than the content div actually has. When opacity reaches 1, the text is fully rendered and goes outside the bounds of the div, causing a small shift.
the problem is not with the visibility, the problem is the transform and transition together, try center the content with top: 50%; and margin-top: negative_half_of_the_div_heigh;.
I'm trying to change my site in a way so that all text is in one page instead of different dirs. In the original the partly transparant background of the container div is scrolling along with the page because otherwise the text would scroll over it. The new page is longer so I thought I would set the background to fixed and just redesign it a bit. But now when I scroll at some point the background disappears. I can't find what is causing this. I'm still learning the ins and outs of using divs, so please, if you know what's causing this, explain it to me in words I understand.
You should to remove height: 100%; from your #home element in your css styles.
Set the background image to another div (#back) rather than to #home.
HTML
<body>
<div id="back"></div>
<div id="home"></div>
</body>
CSS
#back{
position: absolute;
background-image: url('image.jpg');
top: 0;
bottom: 0;
left: 0;
right: 0;
}
I have a page with a text input like the one you can see in this fiddle
Source
Easier to see on JSFiddle...
Notice how the input is slightly off vertical center when you first visit the page. Now click on the text input and watch a set of extra controls expand. Now the text input jumps up to perfect vertical center. Bluring the text input causes the controls to collapse and the text input is no longer at vertical center.
Note: the extra controls will not hide if you enter at least one letter in the text input.
Does anyone have any idea why the input won't stay at vertical center?
Thank you for your time.
It seems to be going off center because the "hidden" state of your controls, although not viewable, is still being rendered in the DOM. However, unlike your "active" state, the "hidden" state's width is declared as 0, causing all the elements to wrap together. This is affecting the vertical height of that element, causing the discrepancy.
I get what you're going for, but the current way you're setting up the CSS won't get you there I don't think. Your current way of centering is dependent entirely on the margin-top: 30px declared on your .options class. What would probably work better is wrapping both the .input and the .options class in a container class, and do your vertical centering there.
Here's an example of what I mean: http://fiddle.jshell.net/YuZHg/6/ (although you can still see the slight wrapping happening on the transition)
A far more solid way to center inline elements vertically is to set line-height to the same value as height.
Add this:
section.explore header {
line-height: 100px;
}
Remove this:
section.explore header div.input {
display: inline-table;
}
And change your <div>s to <span>s so both options and search bar are inline/inline-block elements.
jsFiddle
Of course your transitions are broken now and you'll need to use a different method.
EDIT: After a bit of fiddling I got it mostly working jsFiddle, mostly by removing a bunch of styles :P The width transition doesn't work yet though.
The main issue, by the looks of things is the height on your options div is adding to the container block and pushing down the input.
The css for this is :
section.explore header div.options {
-moz-transition: all .25s ease-in-out;
-ms-transition: all .25s ease-in-out;
-o-transition: all .25s ease-in-out;
-webkit-transition: all .25s ease-in-out;
transition: all .25s ease-in-out;
-moz-opacity: 0;
-ms-opacity: 0;
-o-opacity: 0;
-webkit-opacity: 0;
filter: alpha(opacity=0);
opacity: 0;
display: inline-block;
height: 0;
margin-top: 33px;
max-height: 30px;
max-width: 0px;
overflow: hidden;
position: relative;
text-align: left;
width: 0px;
}
The problem is your a combination of the height, max-height.
There are much easier ways to achieve what you're trying though:
If you know the heights of each of the elements and responsive layout isn't a consideration, just position them accordingly using absolute positioning.
Here's a good article on vertical alignment:

I have this design for an HTML book and i am trying to achieve a certain effect which fading the text when scrolling the page which i successfully done using a fixed div with a superior z-index value and a PNG background image.
.book-bg {
background: url(../../img/book-frame-bg.png) no-repeat fixed center top;
position: fixed;
left: 0;
right: 0;
top: 0;
bottom: 0;
z-index: 100;}
But now all my links which covered by the ".book-bg" div aren't clickable, how can i solve this?

Thanks
In Firefox, Opera and Chrome/Safari you could use pointer-events: none in your CSS rule. If you need IE compatibility as well then try Forwarding Mouse Events Through Layers.
your links will need a higher z-index, for this they will need to be positioned, relative, floated or fixed.
