Header image will not center correctly - html

I'm making a site and trying to center the image head. However, it doesn't appear to be working.
Here is the HTML:
<body>
<div id="templatemo_header">
<div class="image"><img src="images/server_banner_lax_en5.png" alt="Header"></div>
</div>
</body>
And the CSS:
#templatemo_header {
height: 263px;
border-top: 5px solid #FFF;
overflow: visible;
width: 762px;
float: left;
background: url(images/templatemo_headerimg_bg.jpg);
}
#templatemo_header .image {
width: 762px;
margin: 0 auto;
}
I tried to add margin: 0 auto; to the image, but it still is not centered. How can I do this?

Modify the css for the div containing your image with:
margin: 0 auto;
width: 100%;

Add the following to your CSS file:
.image { width:762px; margin:0 auto;}

Your wrapping div is the same width as the image, this stops any margins from being automatically applied since there is no space.
There are a few ways to fix this, but easiest would be to set the width of templatemo_header (the wrapper div) to 100%. This way the image margins can expand, thereby centering the image.
So in your css, modify the width from 762px to 100%, like so:
#templatemo_header {
height: 263px;
border-top: 5px solid #FFF;
overflow: visible;
width: 100%;
float: left;
background: url(images/templatemo_headerimg_bg.jpg);
}

Center floating divs in container

I am currently making a website without using framework however I have run into a problem. My divs are not getting centered within the container even though the container itself is centered in the body.
Html
<body>
<div id="content">
<div class="box">
</div>
<div class="box">
</div>
<div class="box">
</div>
<div class="box">
</div>
</div>
Css
#content{
width: 90%;
height: 100%;
margin: 0 auto;
}
.box{
width: 400px;
height: 150px;
float: left;
border: 1px solid #c8c8c8;
border-radius: 3px;
margin: 13px;
}
The divs are perfectly centered when I have my window to full width, but once I resize it, they just reorganize without centering.
Before resizing:

After resizing the window: http://cl.ly/image/2y2g2W0n230g/Screen%20Shot%202014-09-26%20at%2021.50.21.png
I have tried different methods to solve it, such as doing margin: 0 -10%; and margin: 0 25%;
When it comes to positioning I get confused.
Thanks.
Just change your CSS like this, this way you can adapt your boxes in many ways and they will react to responsive layouts as expected:
#content {
width: 90%;
height: 100%;
margin: 0 auto;
text-align:center;
display:block;
}
.box {
width: 45%;
height: 150px;
display:inline-block;
border: 1px solid #c8c8c8;
border-radius: 3px;
margin: 13px 2%;
}
See fiddle here
Explanation:
I have removed your floats, used block elements and replaced your fixed sizes by percentages. Then, I used a text-align:center property in your container box #content so everything is nicely aligned in the center of that container. Now, if you resize, columns will take 45% of the width of the screen, but you can obviously change the behavior via media queries and use something like .box{display:box} for small screens
There are multiple solutions to your problem. Depending on what you have inside those boxes this might be the simplest one: text-align:centerwith a display:inline-block combo; See here.Fiddle
2 solutions :
You can use a percentage for the width your boxes.
#content{
width: 90%;
height: 100%;
margin: 0 10%;
}
.box{
width: 30%;
height: 150px;
float: left;
border: 1px solid #c8c8c8;
border-radius: 3px;
margin: 13px;
}
Boxes will resize with the content but the stuff in the boxes might look weird in small sizes.
Or
You can use a pixel value for the width of your content.
#content{
width: 1200px;
height: 100%;
margin: 0 10%;
}
.box{
width: 400px;
height: 150px;
float: left;
border: 1px solid #c8c8c8;
border-radius: 3px;
margin: 13px;
}
Width of boxes will not change while resizing, nor the stuff in it, but that can be painful on small screens.
add auto margin for your box
.box{
width: 400px;
height: 150px;
border: 1px solid #c8c8c8;
border-radius: 3px;
margin-top: 13px;
margin-left:auto;
margin-right:auto;
}
I made your files on my machine and the divs are not centered so I assume your screen or resolution settings are different, or your content container is within one or more other divs?
Anyhow, try adding 'clear:left;' in your box class code and it should resolve your issue (put it just above the 'float:left' line. good luck!

CSS positioning issue

I'm having a problem with my CSS where I have a massive amount of white space which I'm not wanting. All I want is the content area containers to fix to the page size, though for the life of me I can't find what I have done to cause this problem.
Here is a link to my problem:
http://jsfiddle.net/k5t5czxt/1/
CSS for main content:
#main-body-area {
background-size:cover;
background:url(../Images/BluePrint.jpg) no-repeat;
background-position:left;
position:absolute;
}
#main-body-cover {
background-color:pink;
opacity: 0.75;
position: absolute;
height: 100%
}
#main-body-wrapper {
width: 60%;
background-color: yellow;
margin: 0px auto;
opacity: 0.75;
border-radius: 20px;
height: 95%;
}
#main-section {
margin: 2%;
}
article {
background-color:orange;
border: 1px solid green;
margin: 2%;
height: 500px;
width: 90%;
display: inline-block;
}
Your extra <div class="Clear" /> and <div class="Clear"></div> are creating the extra white space.
Remove those and the white space will be gone, almost completely. There is still some white space remaining because the overall height of the page is 500px which is a result of your height: 100% element. Removing the height:100% will remove the additional white space but also adversely impact other parts of the page.
Since there is a lot going on with your CSS I would potentially recommend starting over with this page and rebuilding it one element at a time to see how each element and class impacts your layout.
JS Fiddle Demo
The extra white space is caused by your .Clear element. div height: 100% gets applied to that.
Just change CSS for the article.
article {
background-color:orange;
border: 1px solid green;
margin: 2%;
height: 100%;
width: 90%;
display: inline-block;
}
Here, height is changed from 500px to 100%.

Margin-top not working when an image is centered horizontally - Phonegap

I am new to webdesign, I am using Phonegap (HTML5) I centered my image horizontally this way:
.html
<div id="loginholder" >
<img id="image_person" src="img/icon_login.png" />
...
.css
#image_person {
display:block;
margin-left:auto;
margin-right:auto;
margin-top: 30px;
}
...
#loginholder{
background-color: #29AAE1;
height: 200px;
width: 70%;
margin: 0 auto;
}
...
Please why my margin-top is not working?
You need to trigger layout. Add overflow:hidden to #loginholder
I'd add padding-top: 30px; to #loginholder instead and remove the margin-top: 30px; from #image_person:
CSS
#image_person {
display:block;
margin-left:auto;
margin-right:auto;
}
#loginholder {
background-color: #29AAE1;
height: 200px;
width: 70%;
margin: 0 auto;
padding-top: 30px;
}
Check out this JSFiddle: http://jsfiddle.net/bazC4/.
Also, if you wanted the #loginholder the same size, just remove 30px from the height so it would be height: 170px;.
The margin might be collapsing with the parent, causing the 30px margin to appear above the loginHolder div (more on margin collapsing). To resolve this, you could do one of the following:
Add a border or padding to loginHolder; this separates the margins so they won't collapse.
Change to using padding-top on the image instead of margin-top.
Try wrapping it in a div:
JSFIDDLE:
http://jsfiddle.net/MBLKs/
CSS:
#loginholder {
width: 300px;
border: 1px solid red;
overflow: hidden;
position: relative;
}
#stabilizer {
float: left;
position: relative;
left: 50%;
}
img {
display: block;
position: relative;
left: -50%;
}
Images behave like characters, so entering them doesn't always work. In this case, the position of the wrapping div and the image offset each other, leaving the image in the middle. Now your margin-top and everything else should work.

CSS center page on screen

//sorry for the bad formating, i am on my phone...
When someone asks how to center a page, then the response is like:
margin-left:50%;
left:(-1/2 width);
I used this code on a site with a width of 1000px,so it comes to screens, where this site does not fit.
Now the site gets centered on the smaller screen and gets equaly pushet to left and right.
So lets say, our screen is 600px wide:
200px are left
600px are on screen
200px are right
You can scroll to the right, but the pixels on the left are unreachable...
How can i solve this to control, how much of my site gets dragged to the left in case of smaller screens?
This is especially important for mobile phones...
If you are worried about different screen sizes then I highly suggest using Media Queries but this is also a useful way of setting up centered elements. Just use a % width instead of a set width and followed by margin: 0 auto;
Look at fiddle for visual aid. (If this answer does not suit your needs at all then I'll gladly remove it)
div {
margin: 0 auto;
width: 80%;
height: 500px;
background: mediumSeaGreen;
}
JSFIDDLE
Your best bet (Ignore the CSS it's from my portfolio.
.subMenu {
display: none;
float: none;
width: 100%;
background: rgba(254, 126, 1, 0.5);
border-bottom: 5px solid rgba(0, 0, 0, 0.6);
font-size: 20px;
padding-left: 60%;
position: relative;
left: 0;
top: 3.85em;
list-style-type: none;
padding: 1.5em 0;
margin: 0;
overflow: hidden;
}
#media only screen and (max-width: 680px) {
.subMenu {
top: 4.9em;
font-size: 10px;
min-height: 100% !important;
padding: 0;
background: rgba(0, 0, 0, 0.5);
}
}
You can also use jQuery to dynamically find the width.
var width = $('div').width();
$('div').text(width);
You could try using margin: auto
http://jsfiddle.net/56N9w/
As you see there if you make the window too small for the content to fit it will left align by default
Use this:
margin: 0 auto;
width: 400px;
alternative:
margin: 0 auto;
width: 50%;
another alternative:
#outer-div {
margin: 0 auto;
width: 50%;
}
#inner div {
/* insert any CSS you want here */
}
NOTE 1: When using margin: 0 auto, you need to define the width otherwise it won't center.
NOTE 2: You should really put it inside another box, or make the page width 100% (or a width larger than the box).
NOTE 3: You can't center vertically with margin: auto auto. This simply won't work. See below for the solution to this:
Centered box both horizontally and vertically:
Working in jsbin:
http://jsbin.com/OSUViFi/1/
The code (same as the jsbin above):
page.html
<div id="outer-container">
<div id="inner-container">
<div id="centered-box">
</div>
</div>
</div>
style.css
#outer-container {
width: 100%;
height: 100%;
display: table;
position:absolute;
overflow: hidden;
}
#inner-container {
display: table-cell;
vertical-align: middle;
}
#centered-box {
margin: 0 auto;
height: 400px;
width: 400px;
background: #000;
}
Specific for your needs (not including vertical alignment which it looks like you don't need):
jsbin example:
http://jsbin.com/axEZOTo/2
The code (same as the jsbin above):
page.html
<div id="container">
<div id="centered-box">
</div>
</div>
style.css
#container {
width: 1000px;
margin: 0 auto;
height: 100%;
background: #999;
}
#centered-box {
max-width: 70%;
min-width: 200px;
height: 500px;
margin: 0 auto;
background: #000;
}
Here, the smallest it can go is 200px, this number you can change to the smallest amount that you want to allow your box to have.
NOTE:
I finally figured out what you were trying to say in your question, which was poorly worded.
You only used 600px as an example, but you really just want to have it be a fluid layout that changes with screen size.

HTML/CSS: Remove vertical scroll with height: 100%;

I'm creating two columns that I want to fill the page. Very simple. However, I'm getting a very slight vertical scrollbar. Setting margin: 0 and padding: 0 on the html and body didn't fix it.
I've looked into overflow: hidden but I don't like it. I also looked into placing a clear:both div at the bottom, but that didn't do anything. I've looked into using min-height, but I can't seem to get it to work properly.
I have two questions:
Why is that vertical scrollbar appearing?
How can I remove the vertical scrollbar?
Live Example: http://jsfiddle.net/XrYYA/
HTML:
<body>
<div id="palette">Palette</div>
<div id="canvas">Content</div>
</body>
CSS:
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#palette {
float: left;
width: 300px;
height: 100%;
border: 1px solid black;
}
#canvas {
margin-left: 300px;
height: 100%;
border: 1px solid blue;
}
It's because of the 1px borders on each side of the element.
100% + 2px border(s) != 100%.
You could use box-sizing to include the borders in the height of the element.
jsFiddle example
div {
box-sizing:border-box;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box;
}
Alternatively, you could use calc() to subtract the 2px.
height: calc(100% - 2px);
