Positioning div like a chat on the left side of the page? - html

I'm not a css-smarty, I already tried some codes from the internet and stackoverf but still not helping.
How can I fix a div on the left side of page, image can be found down below.
Image: http://prntscr.com/fbhhdi (I selected position with red lines)

If the red outline in your screenshot is, for an example, a div with class="fix-this", then your css would be like this:
.fix-this {
position: fixed;
left: 0;
}
Position fixed will position your div relatively to the viewport.
Left: 0 will place it to the left.
Now, if you also want it to go full height, you can add:
.fix-this {
position: fixed;
left: 0;
top: 0;
bottom: 0;
}

I think it will solve your problem.
body {
background-color: #000;
height: 100%;
padding: 0;
}
.clearfix:after {
visibility: hidden;
display: block;
font-size: 0;
content: " ";
clear: both;
height: 0;
}
#wrapper {
height: 100%;
}
.leftCol {
border: 2px solid red;
color: #fff;
float: left;
min-height: 400px;
height: 100%;
width: 250px;
}
.rightCol {
color: #fff;
float: left;
min-height: 400px;
height: 100%;
width: calc(100% - 254px)
}
<hr></hr>
<div id="wrapper" class="clearfix">
<div class="leftCol">
Content Here
</div>
<div class="rightCol">
Content Here
</div>
</div>

positing in html / css for 100% width divs

I am trying to understand the position in html and css by playing around with an example I have made up. In this example what I have created 3 divs which show color blocks. I am trying to make the first 2 blocks span the width of the screen and the third do just sit as it is on screen. I am trying to have all 3 blocks just stacked on top of each other.
in my html i have created 3 classes:
<div class="color-stripred">
</div>
<div class="color-stripblue">
</div>
<div class="color-stripgreen">
</div>
In my css i have defined the colors, shapes and positions of these blocks:
.color-stripred {
display: block;
height: 20px;
width: 100%;
background-color: red;
position: static;
top: 0;
left: 0;
}
.color-stripblue {
display: block;
height: 20px;
width: 100%;
background-color: blue;
left: 0;
}
.color-stripgreen {
display: block;
height: 20px;
width: 100%;
background-color: green;
left: 0;
}
The red block is on top followed by blue then green. It looks like the following picture:
The problem comes when I try and change the positioning in order to make red and box span the width of the screen. i change the red box css as follows:
.color-stripred {
display: block;
height: 20px;
width: 100%;
background-color: red;
position: fixed;
top: 0;
left: 0;
}
what happens is the redbox spans the width of the screen but the other two boxes shift upwards. how can i stop the blue box and the green box from shifting upwards?
The problem is caused by position: fixed; which you don't even need.
I think what you actually want is to set body { margin: 0; }.
According to W3Schools:
Most browsers will display the <body> element with the following
default values:
body {
display: block;
margin: 8px;
}
body:focus {
outline: none;
}
You can see in the snippet below, that if you add this to your CSS (i.e., remove the margin from the body), all three boxes become full viewport width (even though the width is set to 100%!).
See the snippet below.
body {
margin: 0;
}
.color-stripred {
display: block;
height: 20px;
width: 100%;
background-color: red;
top: 0;
left: 0;
}
.color-stripblue {
display: block;
height: 20px;
width: 100%;
background-color: blue;
left: 0;
}
.color-stripgreen {
display: block;
height: 20px;
width: 100%;
background-color: green;
left: 0;
}
<div class="color-stripred"></div>
<div class="color-stripblue"></div>
<div class="color-stripgreen"></div>
you could add margin-top:20px; to .color-stripblue
.color-stripred {
display: block;
height: 20px;
width: 100%;
background-color: red;
position: fixed;
top: 0;
left: 0;
}
.color-stripblue {
margin-top:20px;
display: block;
height: 20px;
width: 100%;
background-color: blue;
left: 0;
}
.color-stripgreen {
display: block;
height: 20px;
width: 100%;
background-color: green;
left: 0;
}
<div class="color-stripred">
</div>
<div class="color-stripblue">
</div>
<div class="color-stripgreen">
</div>

z-index still getting covered

I'm having a little problem with my footer showing on top of my main content window.
Trying to move the margins so the main content over laps the header by 100px an over laps the footer by 100px and renders to bottom of window.
Not really sure whats wrong could it be to do with "::before" if so is there another way to do this?
Thanks
#wrapper:before {
content: '';
float: left;
height: 100%;
}
#wrapper {
height: 100%;
background-color: black;
}
#header {
z-index: 1;
height: 250px;
text-align: center;
background: url(../images/bg02.jpg);
border-bottom: 10px solid #01A9DC;
}
#main {
z-index: 2;
margin: -100px auto -50px auto;
width: 80%;
background-color: white;
min-height: 400px;
}
#footer {
z-index: 1;
border-top: 10px solid #01A9DC;
background: url(../images/bg02.jpg);
}
#footer:after {
z-index: 1;
content: '';
display: block;
clear: both;
}
<div id="wrapper">
<div id="header"> HEADER<br> </div>
<div id="main"> MAIN CONTENT </div>
<div id="footer"></div>
</div>
z-index has a lot of little tricks. I think roughly it only applies in certain situations, like positioned (relative or absolute) elements or elements with opacity changes. I made your example work here by adding position: relative to your #main element.
#wrapper:before {
content: '';
float: left;
height: 100%;
}
#wrapper {
height: 100%;
background-color: black;
}
#header {
z-index: 1;
height: 250px;
text-align: center;
background: url(../images/bg02.jpg);
border-bottom: 10px solid #01A9DC;
}
#main {
z-index: 2;
position: relative;
margin: -100px auto -50px auto;
width: 80%;
background-color: white;
min-height: 400px;
}
#footer {
z-index: 1;
border-top: 10px solid #01A9DC;
background: url(../images/bg02.jpg);
}
#footer:after {
z-index: 1;
content: '';
display: block;
clear: both;
}
<div id="wrapper">
<div id="header"> HEADER<br> </div>
<div id="main"> MAIN CONTENT </div>
<div id="footer"></div>
</div>
Z-Index is odd. The CSS property position plays a large role in how z-index works.
If you add position: relative; to #main you will see the desired effect.
I would say play around with different positions and z-indexes (as well as nesting these elements) and you will quickly figure out how weird it gets.

height (min-height) 100% not working when content overflow?

I am building a 3 columns layout website. The header will fixed on the top and nav will fixed on the left. Then the wrapper will contain main and aside. What I want is main and aside can fill the wrapper's height.
And here is my css. You can also see my jsFiddle http://jsfiddle.net/scarletsky/h8r2z/3/
* {
margin: 0;
padding: 0;
}
html, body {
width: 100%;
height: 100%;
}
.header {
width: 100%;
height: 100px;
position: fixed;
top: 0;
z-index: 9;
background: red;
}
.nav {
width: 20%;
height: 100%;
position: fixed;
top: 100px;
left: 0;
background: green;
}
.wrapper {
width: 80%;
min-height: 100%;
margin-top: 100px;
margin-left: 20%;
position: relative;
}
.main {
width: 70%;
min-height: 100%;
position: absolute;
left: 0;
background: black;
}
.aside {
width: 30%;
min-height: 100%;
position: absolute;
right: 0;
background: blue;
}
.u-color-white {
color: white;
}
It seems that they can work well. But when the content's height in main or aside more than their own height, it will not work. I don't know how to fix it.
Can anyone help me?
Thx!
You have a very strict layout. everything is fixed..
what if you need to change the header from 100px height to 120? you'll have to change it accordingly in a lot of different places.
This is a pure CSS solution for your layout, without fixing any height or width. (you can fix the height or width if you want to)
This layout is totally responsive, and cross browser.
if you don't fix the height/width of the elements, they will span exactly what they need.
Here's a Working Fiddle
HTML:
<header class="Header"></header>
<div class="HeightTaker">
<div class="Wrapper">
<nav class="Nav"></nav>
<div class="ContentArea">
<div class="Table">
<div class="Main"></div>
<div class="Aside"></div>
</div>
</div>
</div>
</div>
CSS:
* {
margin: 0;
padding: 0;
}
html, body {
width: 100%;
height: 100%;
}
body:before {
content:'';
height: 100%;
float: left;
}
.Header {
height: 100px;
/*No need to fix it*/
background-color: red;
}
.HeightTaker {
position: relative;
}
.HeightTaker:after {
content:'';
display: block;
clear: both;
}
.Wrapper {
position: absolute;
width: 100%;
height:100%;
}
.Nav {
height: 100%;
float: left;
background-color: green;
}
.ContentArea {
overflow: auto;
height: 100%;
}
.Table {
display: table;
width: 100%;
height: 100%;
}
.Main {
width: 70%;
/*No need to fix it*/
background-color: black;
display: table-cell;
}
.Aside {
width: 30%;
/*No need to fix it*/
background-color: black;
display: table-cell;
background-color: blue;
}
.u-color-white {
color: white;
}
This is a pretty common problem. I'd recommend either having a background image for wrapper that makes it appear like aside has a min-height of 100% or using the method on this site:
http://css-tricks.com/fluid-width-equal-height-columns/
just see this fiddle.... hope this is what you want...
.aside {
width: 30%;
min-height: 100%;
position:fixed;
right: 0;
background: blue;
}

HTML/CSS: Layout columns don't fill space

I am trying to make a 3-column layout but as you can see from the screenshot below the left-most and right-most columns don't span all the way down:
You can find the code at http://codepen.io/vbelenky/pen/hvbEq and I'm going to paste it here, too:
<div class="wrapper">
<div class="primary">
<div class="primary-left">
Primary Left<br>
blah
</div>
<div class="primary-right">
Primary Right
</div>
</div>
<div class="secondary">
Secondary
</div>
</div>
CSS:
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
}
.secondary {
width: 200px;
float: left;
background: cyan;
}
.primary {
width: 400px;
float: right;
}
.primary-left {
width: 300px;
float: left;
background: grey;
}
.primary-right {
width: 100px;
float: right;
background: yellow;
}
HTML :
Use follow code that is similar to your query :
<div class="mainDiv">
<div class="left">Left</div>
<div class="center">Center</br>Center<br/>Center<br/></div>
<div class="right">Right</div>
</div>
CSS :
.mainDiv{ position: relative; height: auto;}
.left{ position: absolute;background:red; left: 0; top: 0; width: 100px; height: 100% }
.right{ position: absolute;background:blue; right: 0; top: 0; width: 100px;height: 100%; }
.center{ margin: 0 100px;background:green; }
http://jsfiddle.net/pfqpR/
Like monkhan said, you'll need to set heights for all of the elements, for example (see on CodePen):
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
height: 40px;
}
.secondary {
width: 200px;
float: left;
background: cyan;
height: inherit;
}
.primary {
width: 400px;
float: right;
height: inherit;
}
.primary-left {
width: 300px;
float: left;
background: grey;
height: inherit;
}
.primary-right {
width: 100px;
float: right;
background: yellow;
height: inherit;
}
The downside of this approach is that you'll need to know what the maximum height is ahead of time (in this case, I picked 40px).
One way to approach this is with absolute positions (instead of floats). It doesn't fit to all needs, but it may fit yours.
http://codepen.io/anon/pen/lLngy
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
position: absolute; top: 0; left: 0; bottom: 0;
}
.secondary {
width: 200px;
background: cyan;
position: absolute; top: 0; bottom: 0;
}
.primary-left {
width: 300px;
background: grey;
position: absolute; top: 0; left: 200px; bottom: 0;
}
.primary-right {
width: 100px;
background: yellow;
position: absolute; top: 0; right: 0; bottom: 0;
}
One approach that wouldn't require you to set any pre-determined heights would be to apply a 3-colour background image to the wrapper (image height can be 50px and "repeat-y").
This way you will have the background colours of the inner divs repeating all the way down to the bottom and it won't matter which inner div is the tallest.
For example:
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
background-image: url('3colours.png');
background-repeat: repeat-y;
}
Others said it well. I am just showing another possible way(inconvenient). Inconvenient because it makes the width changing more difficult. Just a background image hack. Use a background image of (wrapper width x 1)px for the .wrapper with colors at appropriate positions. Also remove the background color styles from .secondary, .primary-right and .primary-left.
Here is the fiddle: http://jsfiddle.net/eY9VR/
My coworker gave a solution. The main idea is not to use float property and use display table and table-cell. Please refer to the code for reference. I had to move div.secondary to the top, I commented out the float attribute everywhere, I've declared div.wrapper as display: table and div.secondary, div.primary-left, and div.primary-right as display: table-cell.

Three columns css layout + Togglable one

I'm trying to create a 3 columns layout in css with a togglable one. The following scheme should explain it better than words.
I want the 3 columns be full height.
In red: A static width column
In green: A togglable menu
In dark green: The menu after being toggled
In white: The main container which should fill the rest of the page
I've tried to do it with the following code but without success:
<div id="header"></div>
<div id="inline_container">
<div id="left_menu"></div>
<div id="toggle_menu"></div>
<div id="main_container"></div>
</div>
And with this css code:
* {margin: 0; padding: 0;}
.body {height: 100%; width: 100%;}
#header {height: 70px; width: 100%;}
#inline_container {height: 95%; width: 100%;}
#left_menu {height: 100%; width: 80px; display: inline-block; float: left;}
#toggle_menu {height: 100%; width: 150px; display: inline-block; float: left;}
#main_container {height: 100%; width: 100%; display: inline-block; float: left;}
Did you want something like this?
http://jsfiddle.net/Kcfde/
I've added jQuery script to show toggle effect, just click the green div.
Basically, when you set float and width, elements should remain with display: block, as they'll fit in into content.
Working FIDDLE Demo
For creating full height page, you need a wrapper:
<div id="wrapper">
<!-- MARKUP -->
</div>
That will fill the whole page:
#wrapper {
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
}
Inside our wrapper, we create our wanted elements:
<div id="wrapper">
<div id="red"></div>
<div id="lime">
<div id="green"></div>
<span class="close">[X]</span>
</div>
<div id="white">
TEXT
</div>
</div>
Note that the green element is a child of lime element. If lime get class collapsed, all data
will be hidden and the green one will be display. Here is the CSS:
#wrapper {
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
}
#red {
float: left;
width: 200px;
height: 100%;
background: red;
}
#green {
position: absolute;
right: 0;
top: 0;
bottom: 0;
width: 30px;
background: green;
display: none;
cursor: pointer;
}
#lime .close {
position: absolute;
top: 10px;
right: 10px;
width: 20px;
height: 20px;
background: pink;
cursor: pointer;
}
#white {
height: 100%;
background: gray;
}
#lime {
position: relative;
float: left;
width: 200px;
height: 100%;
background: lime;
transition: width 0.5s;
}
#lime.collapsed {
width: 30px;
}
#lime.collapsed * {
display: none;
}
#lime.collapsed #green {
display: block;
}
And for closing and opening the lime element, we need some JS (I used jQuery):
$(function () {
$('#lime .close').on('click', function () {
$('#lime').addClass('collapsed');
});
$('#green').on('click', function () {
$('#lime').removeClass('collapsed');
});
});
You can see the final FIDDLE Demo.
