I would like to make a top navigation "fixed" bar.
I'm currently experimenting with the code over on W3C.
Unfortunately the navigation bar is not fixed, how can I make it fixed?
NOTE: I have tried position: fixed; but it is not working as expected.
Try this CSS:
.fixed-navbar {
position: fixed;
top: 0;
left: 0;
width: 100%;
}
See https://developer.mozilla.org/en-US/docs/Web/CSS/position
If you use a navbar like that you'll generally want to give it a height (eg 50px) and then offset the rest of your content by that much (eg margin-top: 50px; on your content container.
If you copy their code exactly on W3Schools and add the following onto the ul:
width: 100%;
top: 0;
left: 0;
position: fixed;
You'll get a fixed position on the ul, it will be pushed all the way to the left (no spacing), and all the way up the top (no spacing). Width (100%) just stretches the block across the web-browser (in respect to its size).
You could additionally add a class or an id onto the already existing ul (incase you have multiple existent ul elements) by using div#fixed-navigation for id or div.fixed-navigation for class (in CSS).
So in total you either have: <ul id="fixed-navigation"> or <ul class="fixed-navigation"> (if you choose to use an id or class attribute).
I created a working example for you on JSFiddle: https://jsfiddle.net/799rm54n/

I'm making a website where the top bar needs to be sticky where it is currently.
Please check the code on my git hub repository because its too big to accommodate
my github repository
basically I know that we can do it in 2 ways by making the div tag position: fixed; or position: sticky, but neither of them is working.
To solve this you can simply use:
.sticky{
position: fixed;
top: 0;
width: 100%;
}
position and top is already explained by other user but width is also required to keep the navbar's original form or else the navbar's components becomes disfigured as it loses its position.
In Your first picture we can see that the components have become disfigured
Just make sure your div has the following styles:
position: fixed;
top: 0px;
The top can have whatever value you want. If you want it to be at the very top of the page with no margin, make it 0, or else make it 10px for instance is you want it 10 pixels below the top of the window.
This will make sure your div or header is always at that particular position no matter where you scroll.
I don't really understand how they are making this sidebar stick to the bottom of the page in this bootstrap template.
http://getbootstrap.com/examples/dashboard/#
If you look at the .sidebar class CSS properties, there is this weird
position: fixed; top: 51px; bottom: 0px;
But really no rule about the height of the column, and since it should automatically adjust to the height of the content, I'm a bit lost here.
I made an attempt with this CodePen :
http://codepen.io/anon/pen/ojQvjj
but really, the only way I found to make the sidebar stick to the bottom was to add a height property.
Thanks a lot for the answers, it will really help me make progress with CSS.
If you make a container or element (.sidebar) with position: fixed; + top: 0; bottom: 0; That container will 'stick' to the top and bottom of the parent element (body).
When you use a 'fixed navbar' in bootstrap, you need to add a margin-top > 50px or, in this case,top: 51px; so the sidebar starts after the navbar and it's not hiding behind it.
At some point it will overflow, that's why they add, overflow-y: hidden or scroll;
To be clearer. If you remove those .col-sm-3 .col-md-2 from that element, and give the .sidebar a left: 0; right: 0; it will take the whole viewport area.
Here if you see the code col-md-2 in first div and col-md-10 in second div and making first div as position: fixed; and when we make a div as position fixed it don't acquire any space in view port. and second div with col-md-10 will acquire that place but it will be hidden behind top position of first div so we use .col-md-offset-2 to move second div to 16.66 % right direction and top:0 and bottom:0 for giving position to a fixed div.
and whatever you want is there: please check you this codepen:

I want to add a logo at the bottom of the very first page. Ideally I'd position:absolute it bottom:0 - but anything positioned to the bottom in wkhtmltopdf doesn't seem to work.
This is a problem because the logo is dynamic and could have different heights depending on the aspect-ratio of the uploaded image.
I see that I can add a footer, but this adds it to all pages, and I only want this on one page.
What are my options? Do I have to position-absolute it from the top? If so, what if the page size changes? This needs to work in A4 and US Letter.
I was having the same issue and solved by actually adding a width to the element. So, for the element I want to stick to the bottom I have this css:
.footer {
position: absolute;
bottom: 0;
width: 100%;
}
This didn't work for me. (using python's pdfkit)
I had a one page document and I wanted a footer.
I had to set the height of the page to be the height of a sheet of paper (<body style="height: 297mm">) and then absolute position worked correctly.
Had the same issue, used the answer of Carlo but changed it to use the top margin since it is using the document margins. This way the element was always on the bottom of the first page.
.footer {
position: absolute;
top: 700px;
width: 100%;
}
I've spent all morning trying to write what I thought was a simple bit of code.
Two long columns of content, only column 1 is visible
On click of a link, column 1 is hidden and column 2 becomes visible
Both are in exactly the same position, however both have different and varying lengths
I decided to use the target pseudo-class to switch between the columns, setting the visibility of one to show.
This seems to work, but I don't fully understand what I've done. Plus, content below these columns seems to be placed beneath them on the z-axis rather than below them on the y-axis.
My two (related) issues:
I'm not sure exactly what the logic is of what I've created, I could do with a plain english explanation.
I don't understand why the DIV underneath the two columns and container is not appearing below them on the y-axis.
Here's my CSS:
#container
{
background-color: red;
position: relative;
}
#schools-list
{
width: 400px; /* Set the width of the visible portion of content here */
height: 600px; /* Delete the height, let the content define the height */
background-color: purple;
position: absolute;
top: 0;
left: 0;
}
#boards-list
{
width: 400px; /* Set the width of the visible portion of content here */
height: 700px; /* Delete the height, let the content define the height */
background-color: green;
position: absolute;
top: 0;
left: 0;
visibility: hidden;
}
#container:target #schools-list
{
visibility: hidden;
}
#container:target #boards-list
{
visibility: visible;
}
Here's my HTML:
<div id="container">
<div id="boards-list">
Boards List<br>
Switch to Schools List
Here's some content
</div>
<div id="schools-list">
Schools List<br>
Switch to Boards List
Here's some other content
</div>
</div>
<div>Why is this beneath everything?</div>
Absolute positioning removes an item from the flow of the page. This is what is causing your bottom div to appear underneath.
Visibility removes the element from sight but the element will still take up space.
My suggestion is to use display rather than visibility.
Toggle your elements between display:block and display:none and remove the absolute positioning and you should be able to achieve the functionality you desire.
Both #borad-list and #school-list is taken out of normal page flow by position: absolute, that's why your container height should be 0px as there is nothing that takes any space vertically.
I could explain it better but now writing with my phone so... i'll try just to give you starting point.
By positioning the containers using position:absolute, you're removing them from the normal flow of the page. In other words, your other content acts like those containers aren't even there, and those containers magically appear in front of the content.
Instead, what you'll likely want to do is remove the position, top, and left of the containers, and use display:block to show and display:none to hide the containers. You can also remove the height from the containers and allow the content to decide on its own how much room is needed.
My site, a course catalog tool for universities, has a center pane that contains a dynamically updated list of classes. In Firefox, Opera, and Chrome, the center pane has the intended scrolling behavior: when the class list exceeds the height, the center pane has a scroll bar. IE, however, only shows this bar when the height is explicitly set. Without using JavaScript to reset the center pane height on resize, how can I force Internet Explorer to show the scroll bar?
The center pane:
<div id="middlenav">
<div id="middleheader"></div>
<div id="courselist"></div>
</div>
and its CSS:
div#middlenav {
position: absolute;
left: 250px;
right: 350px;
top: 0px;
bottom: 0px;
}
div#courselist {
overflow: auto;
position: absolute;
top: 55px;
bottom: 0px;
width: 100%;
}
It looks like the center pane isn't obeying the bottom: 0px; statement, and is expanding to the full height of the contained #courselist. I tried body { height: 100% } but that didn't fix it either.
"The top property overrides the bottom property..."
https://developer.mozilla.org/en-US/docs/CSS/bottom
Change top to auto instead of 0px:
div#middlenav
{
position: absolute;
left: 250px;
right: 350px;
top: auto;
bottom: 0px;
}
That should fix the bottom positioning. Remember, if #middlenav is positioned absolutely, it will be relative to whichever parent element has position:absolute; or position:relative;. If #middlenav has no parent elements that are positioned, it will be relative to <body>.
I'm not sure why you have #courselist absolutely positioned; since it is inside of #middlenav I would think you could leave it static or position it relatively. But regardless of what you do, I think you need a height set on #courselist or #middlenav. The default value of height is auto, so there won't be a scrollbar because the element will expand to fit its content.
I know this question was asked 3 years ago, but I'm posting this for other people who may have a problem with CSS positioning. Cheers!
While it is perfectly acceptable to set opposite edges when using absolute positioning in CSS, limitations in Internet Explorer mean that the approach may not work there.
There is no way to avoid the bug in Internet Explorer 6. In Internet Explorer 7 and newer, triggering Standards Mode will resolve the issue.
Faking columns that extend to the bottom of an element is usually achieved using faux columns.
position: absolute; bottom: 0px; sets the element right on the bottom of the element. But it has to know where the bottom of the element is. If you set the height to 100% or have it in another element positioned bottom: 0px; Then it doesn't know where the bottom is, unless one of those elements is inside (taking up the full height of) and element with a fixed size. You can't give the body a height of 100% because it would just sort of go on forever. Try specifying the height of the body or some containing element. :D
Ensure that your doctype is set to HTML strict, otherwise IE will behave quirky and get confused with among others positioning and overflows.
Add this to top of your page:
<!DOCTYPE html>
I am not quite sure if i fully understand but I think you want the center pane to scroll when it reaches past a certain height..this is how I would do it.
#middlenav { position:absolute; left:250px; top:0 }
#courselist { position: absolute;top: 55px; left:0; min-height:400px; _height:400px;
overflow:scroll; overflow-x:hidden; width:500px; }
This sets your course list in all browsers to a minimum height of 400, once that is passed a scrollbar appears. min-height is not supported in IE7 and lower so i used the IE hack _height 400 so it acts as a min height. overflow-x:hidden is hiding the horizontal scroll just in case you only want vertical. I hope this helps you.
Don't use top and bottom positioning in the same class and don't use right and left positioning in the same class, as they are contradictory values to each other.
