I have created an html page and I have used <center> to make it to come at the center of the div like as shown below, but the error alert message is not coming at the center of the portlet-body
Can anyone please tell me some solution for this
Plunker
<div class="portlet-body">
<center>
<div class="alert alert-error">
<strong>Oh snap!</strong> Change a few things up and try submitting again.
</div>
</center>
</div>
You cannot vertical center any element directly unless
- All parents have 100% height.
There are some neat solutions to allow vertical centering, and one latest addition to CSS3 standards called - Flexbox
Some popular tricks:
Use CSS Table-Cell layout
<div class="table">
<div class="table-cell">
<!-- You apply 'vertical-align: center' property to table-cell class -->
</div>
</div>
Use Flex Layout
.container {
display: flex;
align-items: center;
}

how can I place many paragraphs or div elements next to each other, that I see no difference between them? For example:
<div>
<div class="text1">hey, how are</div>
<div class="text2"> you?</div>
</div>
They are placed under each other, but I want them to be side by side, and please don't write me other ways, for example something like: 'you can write the text in one div'... :) I saw this question several times from other users, but they had a bit different problem like mine, so please answer me this question
Thanks
<div>
<span>hey, how ar</span>
<span> you?</span>
</div>
or
.text {
display: inline-block;
}
<div>
<div class="text">hey, how are</div>
<div class="text"> you?</div>
</div>
or
.container {
display: flex;
}
<div class="container">
<div>hey, how are</div>
<div> you?</div>
</div>
div is a block-level element, which means that it will take up the whole of a 'row' on the screen, unlike inline elements.
I'd suggest you have a read through of the MDN pages on these two categories to get a better understanding of this:
Block-level elements
Inline elements
Among the many ways of solving this (change divs to an inline element type like span, using flexbox, etc), one option is to force your div to be inline by changing their CSS:
.text1, .text2 {
display: inline-block;
}
You can do this in many ways. Here I'll be showing classic ways to do this.
using display:inline-block property of css.
.text1{
display:inline-block;
}
.text2{
display:inline-block;
}
using display:flex property of css.
html:
<div class="text-wrapper">
<div class="text1">hey, how are</div>
<div class="text2"> you?</div>
</div>
css:
.text-wrapper{
display: flex;
}
There are several ways of accomplishing this. You could do it with CSS Flexbox, CSS Grid, CSS float, or you could change the display property on the DIV's.
As you have tagged your question with "Angular", it is very common to use the Angular Flex Layout package for positioning (https://github.com/angular/flex-layout). If you add this package to your project, you could solve it like this:
<div fxLayout="row" fxLayoutAlign="start">
<div class="text1">hey, how are</div>
<div class="text2"> you?</div>
</div>
Why don't you use bootsrap? This is a typical scenario for placing things side by side.
<div class="d-flex justify-content-center">
<p></p>
<p></p>
<p></p>
</div>
I'm new to CSS-frameworks.
Normally I start my markup within the body by adding a div with the class "wrap". The purpose of that, is to get the content horizontally centered. And for having a top-, bottom-margin.
Now with Foundation I would like to keep that approach. But I'm not sure where to put the "wrap"-div.
That's what I got currently:
.wrap {
margin: 10px auto;
}
<div class="wrap">
<div class="row">
<div class="small-12 columns">
<div class="callout">
<h1>Lorem Ipsum</h1>
</div>
</div>
</div>
</div>
Demo with Foundation added on CodePen: http://codepen.io/mizech/pen/LWBOvQ
I mean: It works but I'm not sure if I do it right.
Shall I keep it the way it is? Or should I put the "wrap"-div somewhere else?
Should I perhaps leave the "wrap"-div at all (when using Foundation) and doing something else instead?
You don't need a wrap div. Foundation has a maximum width set on the .row so anything inside it will conform to that grid. If you need you can add a class with vertical margins or padding to that row. If you need a full width row you just add the class .expanded to it.
I have a layout that i need to build as can be seen in the image:
Grey stands for header, and there are no problems there. As for the body, I've split it into 3 divs as follows:
<div class="row">
<div class="col-lg-3">
<p>text positioned right here</p>
</div>
<div class="col-lg-6">
<img src="path/to/image.jpg">
</div>
<div class="col-lg-3">
<p>text positioned right here</p>
</div>
</div>
The problem I have is that I need that text to be vertically centered, and I don't know how. I've tried this solution Twitter Bootstrap 3, vertically center content but it doesn't seem to work for me (maybe I'm doing something wrong). I've tried adding padding-top to fix it, but it messes up the mobile display (as expected).
Please, can anyone help?
Thank you.
Text align property is only for horizontal text align, if you want to make text align vertically you need to use position property, we can make using text align something like that. for example: use center of the screen property.
position:relative;
left:50%; top:50%;
also minus margin property off of the container with.
The simplest way to center vertically is to add display:table to the containing element, and display:table-cell to the element you want centered. Bootstrap has a .text-center class to handle the horizontal centering.
http://www.bootply.com/lTigluKakK
Using your example as template:
<div class="col-xs-3 text-center v-align-container">
<p class="v-align-content">text positioned right here</p>
</div>
<div class="col-xs-6 text-center">
<img src="//placehold.it/400x400">
</div>
<div class="col-xs-3 text-center v-align-container">
<p class="v-align-content">text positioned right here</p>
</div>
CSS:
.v-align-container{display: table;height:400px} /* height set to match img (plus padding if needed) */
.v-align-content{display:table-cell;vertical-align:middle}
This works great if you're able to define the height of the sidebar divs. But, if you need them to match the height of the center element dynamically, you'll need a little more bootstrap magic to tie them together, but this will still apply to centering the content within those sidebars.
There are some options I can choose from when it comes to horizontal center alignment with Bootstap.
I can either use offset class or use blank span class as a placeholder.
One other option can be using custom alignment like the following
.center {
float: none;
margin: 0 auto;
}
None of these options solve my issue because the content of the div container has to fill up the width by 100%.
Let's say I have the following
<div class="container-fluid">
<div class="row-fluid">
<div class="span4 offset4">
<button class="btn">1-1</button>
<button class="btn">1-2</button>
</div>
</div>
</div>
If the buttons do not fill up the whole div space of span4, I won't get the real center alignment. Perhaps, I can make the content stretch to 100% but I don't know if this is any good practice.
Here I have a canvas to play with. JS BIN
Since you have inline elements you can just use the .text-center class on the span, also your're probably better off using offsets than empty elements:
HTML
<div class="row-fluid">
<div class="span4 offset4 text-center">
<button class="btn">1-1</button>
<button class="btn">1-2</button>
</div>
</div>
Updated demo: http://jsbin.com/ayuFEhO/2/edit
You don't need add a new class, if you want horizontal align this buttons, just use .text-center here is a bin http://jsbin.com/UVeGejO/1/edit
Obs: text-center class already exist on twitter's bootstrap code.
I am trying to create a 4 column <div> layout.
Why are the row containers not drawing a border around the respective row?
Also, is this a good approach, as in is my css written well to be fluid and for dynamic resizing of the browser window?
Any suggestions or help would be most appreciated.
Here is my current attempt.
You need to set the overflow to auto when using float. http://jsfiddle.net/gJJHs/
The problem seems to be that you are floating your columns, and when you float things, they take up effectively zero space.
I think the solution is to cancel the float in you "last" class and add a "dummy column" to each row.
This CSS seems to work:
.col
{
float: left;
width: 25%;
}
.last{
clear: left;
}
.row{
border: 1px solid green;
}
Revised HTML (with dummy last column):
<div class="row">
<div class="col">1</div>
<div class="col">2</div>
<div class="col">3</div>
<div class="col">4</div>
<div class="last" />
</div>
<div class="row">
<div class="col">5</div>
<div class="col">6</div>
<div class="col">7</div>
<div class="col">8</div>
<div class="last" />
</div>
When an element is floated, its parent no longer contains it because the float is removed from the flow. The floated element is out of the natural flow, so all block elements will render as if the floated element is not even there, so a parent container will not fully expand to hold the floated child element.
As such, the border will seem like it is not bordering anything :( Take a look at the following article to get a better idea of how the CSS Float property works:
The Mystery Of The CSS Float Property
As others have said, if you add overflow: auto; to your .row class, it'll take care of the problem. Here's another article that explains why to use overflow.
http://www.quirksmode.org/css/clearing.html
I hope this helps.

it's the float left. That takes the divs "out of flow" and it's drawing the border around empty space essentially
Yet another option, in addition to the other answers, is to add overflow: hidden; to your .row.
The reason for the behavior you saw is that float takes the div outside of the normal flow. The div then essentially takes up no space in the document.
This makes sense if you think about the ostensible purpose of floating an image in order to wrap text around it. The next p tag (for example) is positioned as if the floated image wasn't there, i.e. overlapping the image. Then, the browser wraps the text within the 'p' tag around the image. (If the floated image was not "removed from the flow", the p tag would naturally appear below the image—not giving the desired effect.)
Here's how I'd write the code.
HTML:
<div class="row">
<div class="col">1</div>
<div class="col">2</div>
<div class="col">3</div>
<div class="col">4</div>
</div>
<div class="row">
<div class="col">5</div>
<div class="col">6</div>
<div class="col">7</div>
<div class="last">8</div>
</div>
CSS:
.col
{
float: left;
width: 25%;
}
.row{
border: 1px solid green;
overflow: hidden; /* "overflow: auto;" works just as well instead */
width:100%; /* Helps older versions of IE */
}
Add a "float:none;clear:both" to your .row and you'll see the rows appropriately. But for the fluid behavior and design that you are looking for, you'll want to apply some javascript (like jQuery Equal Height: http://www.jainaewen.com/files/javascript/jquery/equal-height-columns/) to be consistent across browsers without a ton of CSS hacking.
