Why is div in div - html

I am trying to learn HTML/CSS by trying to make simple website in HTML/CSS. I have so far build some basic skeleton but there is something I cant solve.
I have a problem where div's articlelisting, sidebar1, sidebar2 are placed inside a div footer, but I want to div's articlelisting, sidebar1, sidebar2 be outside footer.
Here is relevant code:
HTML:
<!-- article listing -->
<div class="articlelisting">
articlelisting
</div>
<!-- sidebar 1 -->
<div class="sidebar1">
sidebar1
</div>
<!-- sidebar 2 -->
<div class="sidebar2">
sidebar2
</div>
<!-- footer -->
<div class="footer">
footer
</div>
CSS:
.articlelisting {
display: inline;
width: 48%;
float: left;
}
.sidebar1 {
display: inline;
width: 24%;
float: right;
}
.sidebar2 {
display: inline;
margin-right: 15px;
width: 24%;
float: right;
}
.footer {
width: 100%;
border: solid 1px red;
}
EDIT:
I have placed articlelisting div. Sorry I missed it.
My question is why are divs articlelisting, sidebar1, sidebar2, inside div footer, and how to place them outside div footer?
Thanks

Hey now clear to your footer as like this
.footer{
clear:both;
overflow:hidden;
/// and write some properties as required to
}
Live demo http://tinkerbin.com/9vrEFCqo

Add clear: both; to your footer style. This makes sure the footer stays clear of the preceding divs that are float-ing.
.footer {
clear: both; <-- Add this
width: 100%;
border: solid 1px red;
}​
I posted a working example at jsfiddle

Then put your articlelisting, sidebar1, sidebar2 be outside footer.
and give
.footer {
width: 100%;
border: solid 1px red;
clear:both;
}

HTML produces white space

I am developing a page with Angular 2 and PrimeNG Design Framework. While creating a simple layout consisting out of a menu bar and a content part which should be placed below the menu and fill the whole remaining space. But anyhow there is a gap at the bottom as you can see on the picture and I can't explain myself why.
And this is my HTML- Code
#siteContainer {
height: 100%;
width: 100%;
display: table-row;
}
#menuContainer {
display: table-row;
}
#p-tabView {
height: 100%;
}
<div id="siteWrapper" style="min-height: 100%; width: 100%; display: table">
<!-- Top Menu Bar -->
<div id="menuContainer">
<app-skeleton></app-skeleton>
</div>
<!--Container for site content-->
<div id="siteContainer">
<p-tabView id="tabView" orientation="bottom">
<div id="tabPanelContainer">
<p-tabPanel>
<!--tabbody-->
<p-card>
<app-display-widgets style="{border: #7A7A7A 2em solid;}" *ngIf="sheet.id === refreshCurrentSheet()" [dashboardID]="dashboard.id"></app-display-widgets>
</p-card>
</p-tabPanel>
</div>
</p-tabView>
</div>
</div>
Add margin:0 to your html and body tag
<style>
html, body{
margin: 0;
}
#siteContainer {
height: 100%;
width: 100%;
display: table-row;
background: blue;
}
#menuContainer{
display: table-row;
}
#p-tabView {
height: 100%;
}
add this to your code see if that will fix the problem
body {
margin:0;
padding:0;
}
Check if your router outlet is maybe wrapped inside container fluid, and if so either change container's fluid css to your liking or remove the wrapping div/container

Let sidebar take space of content

I'm trying to figure out how to best implement a sidebar, like the one in the new google plus
I'm using MaterializeCSS
where the "main" content of the page it's width decreases when the sidebar is open and it becomes the fullpage width when the sidebar is closed.
I'm trying to do this with the ui-router.
This is my current setup:
<header>
<div ui-view="header"></div>
</header>
<main ui-view="container"></main>
<footer>
<div ui-view="footer"></div>
</footer>
and each element has it's corresponding controller.
I was thinking of creating a new controller for the sidebar.
But I can't seem to make this work like I want:
this is what I tried:
<main>
<div class="navigation" ng-hide="shownav"><span class="flow-text">This div is 7-columns wide on pushed to the right by 5-columns.</span></div>
<div class="content" ui-view="container"></div>
</main>
css:
main {
width: 100%
}
.navigation {
width: 20%;
float: left;
}
.content {
min-width: 80%;
float: left;
}
Work with float:right and float:left, then position the footer using position: absolute with the parameters like bottom:0 and left:0to position on the bottom and left of the page, setting a width that I want.
Then mark the divs with background-colors and text to see exactly whats happening when I'm coding.
All your content wrapped inside the <main>, because it's where it's gonna the left bar and the content.
I'm sorry if I couldn't explain better
main {
width: 100%;
position: relative;
height: 100%;
}
.navigation {
width: 20%;
float: left;
background: black;
color: white;
height: 100px;
}
.content {
width: 80%;
float: right;
background: red;
color: white;
height: 100px;
}
footer {
position: absolute;
background-color: green;
color: white;
bottom: 0;
left: 0;
width: 100%;
height: 50px;
}
<header>
<div ui-view="header"></div>
</header>
<main ui-view="container">
<main>
<div class="navigation" ng-hide="shownav"><span class="flow-text">This div is 7-columns wide on pushed to the right by 5-columns.</span>
</div>
<div class="content" ui-view="container">aaaaaa</div>
</main>
</main>
<footer>
<div ui-view="footer"></div>
</footer>

Sidebar not positioning correctly

Basically, I don't understand why the isn't at the top right? It positions itself at the bottom, even though by my understanding it should be on the top right?
See JSfiddle for detailed code
http://jsfiddle.net/5JhMj/
#content section {
padding: 4%;
width: 70%;
float: left;
background-color: white;
margin-bottom:8%;
-webkit-box-sizing:border-box;
-moz-box-sizing:border-box;
box-sizing:border-box;
}
aside {
width: 30%;
float: right;
background-color: green;
}
You are floating your sidebar around your last section element.
Instead of this, wrap your sections around another container which you float. Then let your sidebar float aside that new container.
<div class="container">
<div class="section-container">
<section>...</section>
</div>
<aside>
...
</aside>
</div>
CSS
.section-container{
width: 70%;
float: left;
}
aside {
width: 29%;
float: right;
background-color: green;
}
Fiddle:
http://jsfiddle.net/5JhMj/2/
Simple solution is put your aside before section
like
<div class="container">
<aside>
<h1>placeholder</h1>
</aside>
<section>
...

Can I build a web page with <div> rather than <table> and still split pages in several regions?

I am making a web page that needs a header (on top) and a left aligned menu (below the header) and content to the right of that menu.
The problem I am facing is that I want to use (with elements and floats) rather than to create the struture of the page however, whenever I resize the browser window the content element floats down under the menu. I want the content to stick to the right of the left floating menu.
Any one got any ideas how I can fix this?
my html code has this structure:
<div id="menu">
menu #1
...
...
...
</div>
<div id="subcontent">
text or whatnot...
</div>
Css file look like this:
#menu
{
width: 200px;
float: left;
}
#subcontent
{
width: 800px;
float: left;
}
PS I have tried changing pixels to % but with no luck.
CSS
#layout {
min-width: 1001px;
}
#menu {
width: 200px;
float: left;
}
#subcontent {
width: 800px;
float: left;
}
.clear-both {
clear: both;
font: 1px/1px monospace;
display: block;
}
HTML
<div id="layout">
<div id="menu"> menu #1 ...
...
... </div>
<div id="subcontent"> text or whatnot... </div>
<div class="clear-both"></div>
</div>
Another solution:
CSS
#layout {
display: table;
width: 1000px; /* set it to 100% if #subcontent width is dynamic */
}
#menu {
width: 200px;
display: table-cell;
}
#subcontent {
width: 800px; /* you can remove the width to make it dynamic */
display: table-cell;
}
HTML
<div id="layout">
<div id="menu"> menu #1 ...
...
... </div>
<div id="subcontent"> text or whatnot... </div>
</div>
You will need an outer container.
Simply try wrapping both elements in a div of width 1000px
<div class="outer">
<div id="menu">
menu #1
</div>
<div id="subcontent">
</div>
</div>
.outer{width: 1000px;}
#menu
{
width: 200px;
float: left;
}
#subcontent
{
vertical-align: top;
width: 800px;
float: left;
}

How can I position my div at the bottom of its container?

Given the following HTML:
<div id="container">
<!-- Other elements here -->
<div id="copyright">
Copyright Foo web designs
</div>
</div>
I would like #copyright to stick to the bottom of #container. Can I achieve this without using absolute positioning?
Likely not.
Assign position:relative to #container, and then position:absolute; bottom:0; to #copyright.
#container {
position: relative;
}
#copyright {
position: absolute;
bottom: 0;
}
<div id="container">
<!-- Other elements here -->
<div id="copyright">
Copyright Foo web designs
</div>
</div>
Actually, the accepted answer by #User will only work if the window is tall and the content is short. But if the content is tall and the window is short, it will put the copyright info over the page content, and then scrolling down to see the content will leave you with a floating copyright notice. That makes this solution useless for most pages (like this page, actually).
The most common way of doing this is the "CSS sticky footer" approach demonstrated, or a slightly slimmer variation. This approach works great -- IF you have a fixed height footer.
If you need a variable height footer that will appear at the bottom of the window if the content is too short, and at the bottom of the content if the window is too short, what do you do?
Swallow your pride and use a table.
For example:
* {
padding: 0;
margin: 0;
}
html, body {
height: 100%;
}
#container {
height: 100%;
border-collapse: collapse;
}
<!DOCTYPE html>
<html>
<body>
<table id="container">
<tr>
<td valign="top">
<div id="main">Lorem ipsum, etc.</div>
</td>
</tr>
<tr>
<td valign="bottom">
<div id="footer">Copyright some evil company...</div>
</td>
</tr>
</table>
</body>
</html>
Try it out. This will work for any window size, for any amount of content, for any size footer, on every browser... even IE6.
If you're cringing at the thought of using a table for layout, take a second to ask yourself why. CSS was supposed to make our lives easier -- and it has, overall -- but the fact is that even after all these years, it's still a broken, counter-intuitive mess. It can't solve every problem. It's incomplete.
Tables aren't cool, but at least for now, they are sometimes the best way to solve a design problem.
The flexbox approach!
In supported browsers, you can use the following:
Example Here
.parent {
display: flex;
flex-direction: column;
}
.child {
margin-top: auto;
}
.parent {
height: 100px;
border: 5px solid #000;
display: flex;
flex-direction: column;
}
.child {
height: 40px;
width: 100%;
background: #f00;
margin-top: auto;
}
<div class="parent">
<div class="child">Align to the bottom</div>
</div>
The solution above is probably more flexible, however, here is an alternative solution:
Example Here
.parent {
display: flex;
}
.child {
align-self: flex-end;
}
.parent {
height: 100px;
border: 5px solid #000;
display: flex;
}
.child {
height: 40px;
width: 100%;
background: #f00;
align-self: flex-end;
}
<div class="parent">
<div class="child">Align to the bottom</div>
</div>
As a side note, you may want to add vendor prefixes for additional support.
Yes you can do this without absolute positioning and without using tables (which screw with markup and such).
DEMO
This is tested to work on IE>7, chrome, FF & is a really easy thing to add to your existing layout.
<div id="container">
Some content you don't want affected by the "bottom floating" div
<div>supports not just text</div>
<div class="foot">
Some other content you want kept to the bottom
<div>this is in a div</div>
</div>
</div>
#container {
height:100%;
border-collapse:collapse;
display : table;
}
.foot {
display : table-row;
vertical-align : bottom;
height : 1px;
}
It effectively does what float:bottom would, even accounting for the issue pointed out in #Rick Reilly's answer!
Pure CSS, without absolute positioning, without fixing any height, cross-browser (IE9+)
check out that Working Fiddle
Because normal flow is 'top-to-bottom' we can't simply ask the #copyright div to stick to the bottom of his parent without absolutely positioning of some sort, But if we wanted the #copyright div to stick to the top of his parent, it will be very simple - because this is the normal flow way.
So we will use this in our advantage.
we will change the order of the divs in the HTML, now the #copyright div is at the top, and the content follow it right away.
we also make the content div stretch all the way (using pseudo elements and clearing techniques)
now it's just a matter of inverting that order back in the view. that can be easily done with CSS transform.
We rotate the container by 180deg, and now: up-is-down. (and we inverse back the content to look normal again)
If we want to have a scroolbar within the content area, we need to apply a little bit more of CSS magic. as can be showed Here [in that example, the content is below a header - but its the same idea]
* {
margin: 0;
padding: 0;
}
html,
body,
#Container {
height: 100%;
color: white;
}
#Container:before {
content: '';
height: 100%;
float: left;
}
#Copyright {
background-color: green;
}
#Stretch {
background-color: blue;
}
#Stretch:after {
content: '';
display: block;
clear: both;
}
#Container,
#Container>div {
-moz-transform: rotateX(180deg);
-ms-transform: rotateX(180deg);
-o-transform: rotate(180deg);
-webkit-transform: rotateX(180deg);
transform: rotateX(180deg);
}
<div id="Container">
<div id="Copyright">
Copyright Foo web designs
</div>
<div id="Stretch">
<!-- Other elements here -->
<div>Element 1</div>
<div>Element 2</div>
</div>
</div>
CSS Grid
Since the usage of CSS Grid is increasing, I would like to suggest align-self to the element that is inside a grid container.
align-self can contain any of the values: end, self-end, flex-end for the following example.
#parent {
display: grid;
}
#child1 {
align-self: end;
}
/* Extra Styling for Snippet */
#parent {
height: 150px;
background: #5548B0;
color: #fff;
padding: 10px;
font-family: sans-serif;
}
#child1 {
height: 50px;
width: 50px;
background: #6A67CE;
text-align: center;
vertical-align: middle;
line-height: 50px;
}
<div id="parent">
<!-- Other elements here -->
<div id="child1">
1
</div>
</div>
Create another container div for the elements above #copyright. Just above copyright add a new div:
<div style="clear:both;"></div>
It will force the footer to be under everything else, just like in the case of using relative positioning (bottom:0px;).
Try this;
<div id="container">
<div style="height: 100%; border:1px solid #ff0000;">
<!-- Other elements here -->
</div>
</div>
<div id="copyright" style="position:relative;border:1px solid #00ff00;top:-25px">
Copyright Foo web designs
</div>
While none of the answers provided here seemed to apply or work in my particular case, I came across this article which provides this neat solution :
#container {
display: table;
}
#copyright {
display: table-footer-group;
}
I find it very useful for applying responsive design for mobile display without having to reorder all the html code of a website, setting body itself as a table.
Note that only the first table-footer-group or table-header-group will be rendered as such : if there are more than one, the others will be rendered as table-row-group.
You can indeed align the box to the bottom without using position:absolute if you know the height of the #container using the text alignment feature of inline-block elements.
Here you can see it in action.
This is the code:
#container {
/* So the #container most have a fixed height */
height: 300px;
line-height: 300px;
background:Red;
}
#container > * {
/* Restore Line height to Normal */
line-height: 1.2em;
}
#copyright {
display:inline-block;
vertical-align:bottom;
width:100%; /* Let it be a block */
background:green;
}
Using the translateY and top property
Just set element child to position: relative and than move it top: 100% (that's the 100% height of the parent) and stick to bottom of parent by transform: translateY(-100%) (that's -100% of the height of the child).
BenefitS
you do not take the element from the page flow
it is dynamic
But still just workaround :(
.copyright{
position: relative;
top: 100%;
transform: translateY(-100%);
}
Don't forget prefixes for the older browser.
CodePen link here.
html, body {
width: 100%;
height: 100%;
}
.overlay {
min-height: 100%;
position: relative;
}
.container {
width: 900px;
position: relative;
padding-bottom: 50px;
}
.height {
width: 900px;
height: 50px;
}
.footer {
width: 900px;
height: 50px;
position: absolute;
bottom: 0;
}
<div class="overlay">
<div class="container">
<div class="height">
content
</div>
</div>
<div class="footer">
footer
</div>
</div>
If you want it to "stick" to the bottom, regardless of the height of container, then absolute positioning is the way to go. Of course, if the copyright element is the last in the container it'll always be at the bottom anyway.
Can you expand on your question? Explain exactly what you're trying to do (and why you don't want to use absolute positioning)?
If you do not know the height of child block:
#parent {
background:green;
width:200px;
height:200px;
display:table-cell;
vertical-align:bottom;
}
.child {
background:red;
vertical-align:bottom;
}
<div id="parent">
<div class="child">child
</div>
</div>
http://jsbin.com/ULUXIFon/3/edit
If you know the height of the child block add the child block then add padding-top/margin-top:
#parent {
background:green;
width:200px;
height:130px;
padding-top:70px;
}
.child {
background:red;
vertical-align:
bottom;
height:130px;
}
<div id="parent">
<div class="child">child
</div>
</div>
You can use grid by assigning the available space to the content at the top:
#container {
display: grid;
grid-template-rows: 1fr auto;
height: 10rem; /* or 100% or anything */
}
<div id="container">
This is random content.
<div id="copyright">
Copyright Foo web designs
</div>
</div>
Also, if there's stipulations with using position:absolute; or position:relative;, you can always try padding parent div or putting a margin-top:x;. Not a very good method in most cases, but it may come in handy in some cases.
Solution for this specific scenario:
Place inner at the bottom of parent . The height of the parent is set by the height of its "tallest" sibling
The set up:
I have a row with multiple <div class="container">
These <div class="container"> are next to each other inside another <div class="supercontainer">
Each <div class="container"> has 3 inner divs on top of each other: <div class="title">, <div class="content">, <div class="footer">
The desired result:
All <div class="container"> have the same height. The height is not defined in px, it will be the height of the "tallest" among them.
<div class="title"> should be at the top of <div class="container">
<div class="content"> should be placed below <div class="title">
<div class="footer"> should be placed at the bottom of <div class="container"> without overlapping with the previous content

Don't wanna use "position:absolute" for sticky footer at bottom. Then you can do this way:
html,
body {
height: 100%;
margin: 0;
}
.wrapper {
min-height: 100%;
/* Equal to height of footer */
/* But also accounting for potential margin-bottom of last child */
margin-bottom: -50px;
}
.footer{
background: #000;
text-align: center;
color: #fff;
}
.footer,
.push {
height: 50px;
}
<html>
<body>
<!--HTML Code-->
<div class="wrapper">
<div class="content">content</div>
<div class="push"></div>
</div>
<footer class="footer">test</footer>
</body>
</html>
Here is an approach targeted at making an element with a known height and width (at least approximately) float to the right and stay at the bottom, while behaving as an inline element to the other elements. It is focused at the bottom-right because you can place it easily in any other corner through other methods.
I needed to make a navigation bar which would have the actual links at the bottom right, and random sibling elements, while ensuring that the bar itself stretched properly, without disrupting the layout. I used a "shadow" element to occupy the navigation bar's links' space and added it at the end of the container's child nodes.
<!DOCTYPE html>
<div id="container">
<!-- Other elements here -->
<div id="copyright">
Copyright Foo web designs
</div>
<span id="copyright-s">filler</span>
</div>
<style>
#copyright {
display:inline-block;
position:absolute;
bottom:0;
right:0;
}
#copyright-s {
float:right;
visibility:hidden;
width:20em; /* ~ #copyright.style.width */
height:3em; /* ~ #copyright.style.height */
}
</style>
Maybe this helps someone: You can always place the div outside the other div and then push it upwards using negative margin:
<div id="container" style="background-color: #ccc; padding-bottom: 30px;">
Hello!
</div>
<div id="copyright" style="margin-top: -20px;">
Copyright Foo web designs
</div>
Just because this hasn't been mentioned at all, what usually works well in situations like yours:
Placing the copyright-div after the container-div
You would only have to format the copyright-div in a similar way to the other container (same overall width, centering, etc.), and all is fine.
CSS:
#container, #copyright {
width: 1000px;
margin:0 auto;
}
HTML:
<div id="container">
<!-- Other elements here -->
</div>
<div id="copyright">
Copyright Foo web designs
</div>
The only time this might not be ideal is when your container-div is declared with height:100%, and the user would need to scroll down to see the copyright. But even still you could work around (e.g. margin-top:-20px - when the height of your copyright element is 20px).
No absolute positioning
No table layout
No crazy css, that looks different in every other browser (well IE at least, you know)
Simple and clear formatting
Aside: I know the OP asked for a solution that "... sticks to the bottom of the 'container' div ...", and not something under it, but come on, people are looking for good solutions here, and this is one!
There is nothing called float:bottom in CSS. The best way is using positioning in such cases:
position:absolute;
bottom:0;
For those only have one child in the container, you can use the table-cell and vertical-align approach which worked reliably for positioning a single div at the bottom of its parent.
Note that using table-footer-group as other answers mentioned will break the height calculation of parent table.
#container {
display: table;
width: 100%;
height: 200px;
}
#item {
display: table-cell;
vertical-align: bottom;
}
<div id="container">
<div id="item">Single bottom item</div>
</div>
According: w3schools.com
An element with position: absolute; is positioned relative to the
nearest positioned ancestor (instead of positioned relative to the
viewport, like fixed).
So you need to position the parent element with something either relative or absolute, etc and position the desired element to absolute and latter set bottom to 0.
