I have an element that is fixed and has a margin from the left of the screen. I want to make this element right of a wrapper instead because people who have smaller resolutions or larger will have the element really far away or really close to my wrapper.
I hope this makes sense! :S
Thanks
Using both fixed and relative on the same element is as far as I know impossible.
What you could do is a jQuery solution.
But is the fixed position really necessary? How about fixing the wrapper then just using relative on the other document to position it relative to the wrapper?
That should solve it.
You could use something like this :
HTML
<div id="wrapper">
<div id="fixed"></div>
</div>
CSS
#wrapper {
width: 400px;
height: 600px;
margin: 0 auto;
}
#fixed {
width: 40px;
height: 100px;
position: fixed;
top: 0;
margin-left: 400px;
}

Is there a quick and easy way to keep a navigation not moving while resizing the window ?
What I have at the moment is something like this which is obviously wrong because proportions will change.
I am not sure if I should use a fixed width though ?
#mainnav {
position: absolute;
left: 30%;
top: 75px;
width: 50%;
}
Thank you for your answers.
It really depends on what kind of page you are creating. If you are creating something responsive/interactive, you may need fixed or absolute navigation, but it's hard to tell from the code that you provided.
A more traditional approach would be to wrap your page content in a container with a fixed width:
<div id="container">
<div id="mainnav">...</nav>
<div id="main-content">...</div>
</div>
CSS
#container
{
width: 1000px;
margin: 0 auto; // will center your container inside page body, even on resize
}
#mainnav
{
display : block;
}
This way your nav will stay together with the content and wont resize. it's also much easier to manage what's inside the navigation element.
I am relatively new to front-end dev so a bit lost as to how i can go about this. I created a container that contains a slider and some images. My supervisor has a huge screen so obviously there will be empty space at the bottom of the screen. So he doesn't want that. Instead he wants the container to be centered horizontally and vertically based on the size of the user's screen.
How can I do this properly with as minimal code as possible? I believe there is jQuery plugin but wanted to see if there is a better way or if doing this makes sense at all or not?
Due to the flow-based nature of CSS, without Javascript this can only be done if the vertical size of the centered element is fixed, by applying a position:absolute' andtop:50%` within a fixed container, and then use negative margin to offset the container. Click here for JSFiddle Sample.
Alternatively the same effect can be reached by using display:table-cell, but that's kind of messy and loses you a lot of flexibility. Sample already supplied in the other answer here so I'll save myself the effort :)
You can do it easily using a vertical-align property.
Since vertical-align works the desired way way only in a table cell, this trick with display property can give you the desired effect.
#yourDiv {
// give it a size
width: 100px;
height: 100px;
margin: 0 auto;
}
html, body {
height: 100%;
width: 100%;
padding: 0; margin: 0;
}
html {
display: table;
}
body {
display: table-cell;
vertical-align: middle;
}
See a fiddle with demo.
Try this:
HTML:
<div class="center"></div>
CSS:
.center {
width: 300px;
height: 300px;
position: absolute;
left: 50%;
top: 50%;
margin-left: -150px;
margin-top: -150px;
background-color: red;
}

Exactly Center an Image/Div Horizontally and Vertically:
http://css-tricks.com/snippets/css/exactly-center-an-imagediv-horizontally-and-vertically/
I have a fixed positioned element somewhere near bottom of my page. As there is more content to it than window height itself displays rest of it's been cut down.
I've tried adding overflow:auto to fix this issue and be capable of scrolling through fixed positioned element but no luck.
I suppose there might be a javascript solution near by but wondering if there is a css one as well.
Hope my question made sense.
Thanks
You have to fix the height/width to get scrollbars, otherwise the fixed element expands out of view. Here's a little demo: little link. Basic outine:
HTML:
<div class = "fixed">
Glee is awesome!<br/>
...
Glee is awesome!<br/>
</div>
CSS:
html, body {
height: 100%;
}
.fixed {
position: fixed;
left: 0px;
top: 0px;
height: 100%;
width: 100px;
overflow: auto;
}
I have read other questions on stackoverflow about centering and have used this technique before.
I tried using:
<div style="width: 1000px; position: absolute; margin: 300px auto 0px auto;">
content in here
</div>
This did not center the div. What have I done wrong? I feel like I have used this code before, but it will not work this time. I tried making a new html file, and I tried it in case I had done something wrong on this particular page. It was flawed as well. How is it wrong?
Get rid of position: absolute.
jsFiddle.
BTW, it as nothing to do with the fact the styles are inline.
The auto margin trick doesn't work for elements that have absolute positioning. Try the following instead:
width: 1000px;
position: absolute;
top: 300px;
left: 50%;
margin-left: -500px;
This works by centring the LHS of the element using left: 50% then centering the element by using a negative margin of exactly half it's width.
How to horizontally center a floating element of a variable width?
Edit: I already have this working using a containing div for the floating element and specifying a width for the container (then use margin: 0 auto; for the container). I just wanted to know whether it can be done without using a containing element or at least without having to specify a width for the containing element.
Assuming the element which is floated and will be centered is a div with an id="content"
...
<body>
<div id="wrap">
<div id="content">
This will be centered
</div>
</div>
</body>
And apply the following CSS:
#wrap {
float: left;
position: relative;
left: 50%;
}
#content {
float: left;
position: relative;
left: -50%;
}
Here is a good reference regarding that.
.center {
display: table;
margin: auto;
}
You can use fit-content value for width.
#wrap {
width: -moz-fit-content;
width: -webkit-fit-content;
width: fit-content;
margin: auto;
}
Note: It works only in latest browsers.
This works better when the id = container (which is the outer div) and id = contained (which is the inner div). The problem with the highly recommended solution is that it results in some cases into an horizontal scrolling bar when the browser is trying to cater for the left: -50% attribute. There is a good reference for this solution
#container {
text-align: center;
}
#contained {
text-align: left;
display: inline-block;
}
Say you have a DIV you want centred horizontally:
<div id="foo">Lorem ipsum</div>
In the CSS you'd style it with this:
#foo
{
margin:0 auto;
width:30%;
}
Which states that you have a top and bottom margin of zero pixels, and on either left or right, automatically work out how much is needed to be even.
Doesn't really matter what you put in for the width, as long as it's there and isn't 100%. Otherwise you wouldn't be setting the centre on anything.
But if you float it, left or right, then the bets are off since that pulls it out of the normal flow of elements on the page and the auto margin setting won't work.
The popular answer here does work sometimes, but other times it creates horizontal scroll bars that are tough to deal with - especially when dealing with wide horizontal navigations and large pull down menus. Here is an even lighter-weight version that helps avoid those edge cases:
#wrap {
float: right;
position: relative;
left: -50%;
}
#content {
left: 50%;
position: relative;
}
Proof that it is working!
To more specifically answer your question, it is probably not possible to do without setting up some containing element, however it is very possible to do without specifying a width value. Hope that saves someone out there some headaches!
Can't you just use display: inline block and align to center?
Example.
for 50% element
width: 50%;
display: block;
float: right;
margin-right: 25%;
