Item with fixed position not appearing in right place - css

Question

I'm trying to add page-to-top code to a page. Everything works fine except for the positioning of the "to top" button.
I've shown the problem in this jsfiddle. You can see the To Top in the lower right. I need it to be in the lower right of the middle div.
My code is below. I looked up the fixed position description and it says it aligns to the viewport. Is there a way to override that so it aligns to a specific div?
.layout {
float: left;
width: 150px;
height: 200px;
border: 1px solid red;
}
#toTop {
padding: 5px 3px;
position: fixed;
bottom: 0;
right: 5px;
z-index: 100;
}
<div>
<div class="layout">Left column</div>
<div class="layout">Middle column
<span id="toTop">To Top</span>
</div>
<div class="layout">Right column</div>
</div>

Answer 1

You should add position: relative; to .layout and position: absolute; to #toTop. The absolute positioned element will have its relative parent as base

Answer 2

.layout {float:left; width:150px;height:200px;border:1px solid red;position: relative;}
div > span { position: absolute; right: 0; bottom: 0; }

This will do it for you.
I added the relative position and in the div > span positioned it absolute and right 0 and bottom 0

Answer 3

I have changed couple of styles in your CSS code. The example is here

Though i am not sure if you want something like this. Please let me know.
I have removed float from your divs and added inline-block as display. Also changed some position value to achieve the result.
.layout {display: inline-block; width:150px;height:200px;border:1px solid red;}
.middle {
position: relative
}
#toTop {
/* padding: 5px 3px; */
position: absolute;
bottom: 0;
right: 0;
z-index:100;
}
<div>
<div class="layout">Left column</div>
<div class="layout middle">Middle column
<span id="toTop">To Top</span>
</div>
<div class="layout">Right column</div>
</div>

Answer 4

.layout should be positioned and .top should be absolute.
.layout{
position:relative;
}
.top{
position :absolute
}

If you want to keep that "To Top" button always visible on the bottom of the viewport, then you would have to position it relative to the viewport in a way that it matches the location you want, relative to the parent.
body {
margin: 0;
font-family: monospace;
}
.container {
display: flex;
height: 200vh;
width: 90vw;
border: 3px solid red;
margin: 10px auto;
}
.layout {
border-left: 3px solid red;
width: 33.33333333%;
text-align: center;
padding: 10px;
}
.layout:first-child{
border-left: none;
}
#totop {
font-family: monospace;
border: 3px solid red;
background: white;
padding: 10px;
position: fixed;
bottom: 10px;
z-index: 100;
right: calc(35vw + 10px);
outline: none;
}
#totop:hover {
background: red;
color: white;
}
<div class="container">
<div class="layout">Left column</div>
<div class="layout">Middle column
<button id="totop">TO TOP</button>
</div>
<div class="layout">Right column</div>
</div>
<div class="container">
<div class="layout">Something else here.</div>
<div>
Note, however, that as you pointed out in your comment, this means the "To Top" would still be visible even when you scroll past that first .container element.
To avoid that, if you just want that button to be at the bottom of its column, even if that's outside of the viewport and the user needs to scroll down to get to it, then you should use position: absolute instead and also add position: relative to .layout:
body {
margin: 0;
font-family: monospace;
}
.container {
display: flex;
height: 200vh;
width: 90vw;
border: 3px solid red;
margin: 10px auto;
}
.layout {
position: relative;
border-left: 3px solid red;
width: 33.33333333%;
text-align: center;
padding: 10px;
}
.layout:first-child{
border-left: none;
}
#totop {
font-family: monospace;
border: 3px solid red;
background: white;
padding: 10px;
position: absolute;
bottom: 10px;
right: 10px;
outline: none;
}
#totop:hover {
background: red;
color: white;
}
<div class="container">
<div class="layout">Left column</div>
<div class="layout">Middle column
<button id="totop">TO TOP</button>
</div>
<div class="layout">Right column</div>
</div>
<div class="container">
<div class="layout">Something else here.</div>
<div>
To get the best of both worlds, and make the "To Top" button stay at the bottom of the viewport until the end of the first .container is reached, and remain inside it when the user scrolls past it, you could use position: sticky:
body {
margin: 0;
font-family: monospace;
}
.container {
display: flex;
height: 200vh;
width: 90vw;
border: 3px solid red;
margin: 10px auto;
}
.layout {
position: relative;
border-left: 3px solid red;
width: 33.33333333%;
text-align: center;
padding: 10px;
}
.layout:first-child{
border-left: none;
}
#totop {
position: -webkit-sticky;
position: -ms-sticky;
position: sticky;
font-family: monospace;
border: 3px solid red;
background: white;
padding: 10px;
top: calc(100vh - 49px);
float: right;
outline: none;
}
#totop:hover {
background: red;
color: white;
}
<div class="container">
<div class="layout">Left column</div>
<div class="layout">Middle column
<button id="totop">TO TOP</button>
</div>
<div class="layout">Right column</div>
</div>
<div class="container">
<div class="layout">Something else here.</div>
<div>
The only problem with this approach could be browser support.
In that case, if you really need this feature/behaviour, you could implement your own sticky element using JS and listening for the onscroll and 'onresize' events.
Alternatively, you can use JS to check if position: fixed is supported and apply one solution or another:
const hasSticky = (() => {
const el = document.createElement('div');
el.style.cssText = "position:sticky;position:-webkit-sticky;position:-ms-sticky;";
return el.style.cssText.indexOf('sticky')!==-1;
})();
if (hasSticky) {
document.getElementById('totop').classList.add('sticky');
}
body {
margin: 0;
font-family: monospace;
}
.container {
display: flex;
height: 200vh;
width: 90vw;
border: 3px solid red;
margin: 10px auto;
}
.layout {
position: relative;
border-left: 3px solid red;
width: 33.33333333%;
text-align: center;
padding: 10px;
}
.layout:first-child{
border-left: none;
}
#totop {
font-family: monospace;
border: 3px solid red;
background: white;
padding: 10px;
position: absolute;
bottom: 10px;
right: 10px;
outline: none;
}
#totop.sticky {
position: -webkit-sticky;
position: -ms-sticky;
position: sticky;
bottom: auto;
top: calc(100vh - 49px);
right: auto;
float: right;
}
#totop:hover {
background: red;
color: white;
}
<div class="container">
<div class="layout">Left column</div>
<div class="layout">Middle column
<button id="totop">TO TOP</button>
</div>
<div class="layout">Right column</div>
</div>
<div class="container">
<div class="layout">Something else here.</div>
<div>

Answer 6

I changed the scroll code I was using to look for the last button on the page and to hide the To Top button when it reached it. Here is my updated jsfiddle and code. The numbers are not quite correct but I'm just posting this in case someone else runs across this problem. I'm not sure if it is the best solution but I've tested it here and it seems to work fine. My tnaks to all who replied.
<style>
.container {
display: flex;
height: 150vh;
width: 100vw;
}
.layout {float:left; width:150px;height:250px;border:1px solid red;}
.layout-middle {position:relative;float:left; width:150px;height:250px;border:1px solid red;}
#toTop {
font-family: monospace;
border: 3px solid red;
background: white;
padding: 10px;
position: fixed;
bottom: 60px;
z-index: 100;
right: calc(45.33333333% + 10px);
outline: none;
}
</style>
<div class="container">
<div class="layout">Left column</div>
<div class="layout-middle">Middle column
<span id="toTop">To Top</span>
</div>
<div class="layout">Right column</div>
</div>
<div><button id="button-isvisible">Button</button></div>
<script>
$(document).ready(function($){
var offset = 20;
var duration = 500;
$(window).scroll(function() {
var continue_button_pos = $('#button-isvisible').offset();
var button_top = continue_button_pos.top - 350 ;
if ($(this).scrollTop() > button_top) {
$('#toTop').fadeOut(duration);
} else if ($(this).scrollTop() > offset) {
$('#toTop').fadeIn(duration);
} else {
$('#toTop').fadeOut(duration);
}
});
});
</script>
