I have a div which i want vertically aligned to 50% of the height of the browser window at all times.
I don't know what the height of the browser window is going to be at all times, should the user scale this window. If placing it within another element is necessary, great, but as just specified, I have no idea how tall the viewport is going to be at any one time.
I'm not going to be using javascript either.
I have read through the site, i have gone hunting for a solution, but I really want to throw this out there (again) as I have yet to find a solution that does exactly this, either by hook or by crook.
Thanks.
You don't specify if the has a fixed height or not? If so then you can do this with one element, just add the following example CSS:
.centered {
height: 100px;
width: 100%;
background: red;
position: absolute;
top: 50%;
left: 0;
margin-top: -50px; /* half the height of the element */
}
You could use a number of techniques, depends on how you exactly want to implement it. Some (older) but still relevant reading here.

Im trying to accomplish this:
http://codepen.io/Mest/pen/oKBIu?editors=110
.child-div {
width: 100vw;
position: relative;
left: calc(-50vw + 50%);}
but instead of a "child-div" i want to target an img-class, like this:
http://codepen.io/dantveita/pen/ZGdKmd
.parent-div img {
width: 100vw;
position: relative;
left: calc(-50vw + 50%);}
When i do this, im getting a horizontal scrollbar, and im not sure why. Could anyone explain this to me. And if possible, provide a solution?
Thanks
Since you are using position: relative, moving the image to the left doesn't actually take it outside of the document flow, so, according to the browser, it still thinks the image is sticking out.
Because there are no containing elements, there's also no need to use viewport-width over a percentage. For some reason, using viewport-width instead of a percentage adds a little extra space on the right, underneath the scrollbar, even when the image is absolutely positioned.
However, this works:
.parent-div img {
position: absolute;
left: 0;
width: 100%;
}
You may also want to remove the width="1400px" from your image tag, as it isn't necessary and may cause inheritance issues later on.
Im going to go with
.parent-div img {
display:block;
width: 100vw;
position: relative;
left: calc(-50vw + 50%);}
on the img-class for now, while hiding overflow-x, until something comes up that makes hiding the scrollbar prevent users from viewing content.
The reason for using this method, and not closing the "previous" container (which would be the obvious choice) is that i want a quick solution for a wordpress blogtemplate, where all images given a specific img-class will stretch full width, when media is inserted from post-editor.
Heres an example of the effect im looking for (theverge.com is obviously closing containers):

Please visit my website at http://amrapps.ir/personal/indexbug.html
to visually see my problem.
Let me explain my problem:
In my website i have a fixed postion div which contains links and i takes and it takes 25 % of browser height.
Then it is the red div which takes 75 % of browser width.
When user clicks on -CLICK THERE TO READ MORE- in red div,it will be redirected to the next(yellow colored) div which takes 100 % of browser height.
Then you can click on go to top on the fixed div above to get back to red div.
Navigations are working well but there's a problem.
When you are at the 2nd(yellow) div,if you change browser width,the red div will be also visible! How can i fix that?
thank you for your effort.
Change your #aboutmore class to the below css:
#aboutmore {
background-color: #FFCE85;
margin-top: 5px;
top: 25%;
position: absolute;
/* height: 74%; */
width: 100%;
min-width: 1130px;
bottom: 0px;
z-index: 3;
}
Theres a couple of things going on here, and I'm not 100% of the result you want to accomplish, but we are working with CSS heights here so you need to keep some things in mind.
First of: when working with css heights, you need to make sure that all wrapping elements get the height of 100%. Including your body AND html tags. Without this, your body will just have the height of the elements inside it, and your 100% divs will do it to.
Second, you should turn of the body 'overflow: hidden' attribute, as it just obstructs correct testing.
Now, like I said, I'm not sure what you're trying to accomplish, but your header should be taken out of the wrapper as it is fixed. This will allow your wrapper to become the scrollable area. You also mentioned you wanted the second div to be 100% heigh and the first one 75%. Now, with position fixed this would mean your yellow div is only 75% visible, with 25% hidden (either by being off screen or under the header). If you want the first div and header together to take up 100%, and any subsequent div to take up 100% on their own, you should position all elements relative and not fixed.
I'm going to add some code here to help with a fixed header:
div#page-wrap {
height: 75%;
position: absolute;
top: 25%;
width: 100%;
overflow: scroll;
overflow-x: hidden;
}
about,
#aboutmore {
height: 100%;
position: relative;
top: 0%;
}
Now this will break your javascript (as you can't actually scroll the body), although I couldn't get it working in the first place anyhow. You'll find more about scrolling inside a div (as now you need to scroll in your wrapper element) in this thread: How do I scroll to an element within an overflowed Div?
I'm trying to set up a responsive header that takes an image and resizes it to the browser – easy enough. What I can't manage to achieve is centring the image vertically within it's container (in this case an a element)
See example:
http://jsfiddle.net/jwoodcreative/tUW3k/
I've tried a few css tricks that havent worked and some jQuery. Either type of solution would suit if anyone knows of one.
You can always use the top:50%, bottom: 50% trick like here: jsfiddle v13
.outerElement {
position: relative;
height: XXpx;
top: 50%;
}
.innerElement {
position: absolute;
bottom: 50%;
}
This works, because the height of the innerElement is not the same as the one of the outer Element, so you can center your element (if the heights were identical, you'd just position it to pos:0 again)
Like this? I've changed the image to be a background-image, which can be centered very easily in CSS. To make sure the link is shown, I have added a non-breaking space ( ). I think this is what you want, right?
You can change the appearance of the image more by looking here, at the documentation of the background property.
First, I wonder if anyone can even say that question title ten times fast.
This should be pretty easy. I've been googling around, and while there are a lot of tutorials on it, I'm having trouble grasping the idea overall. I've even looked at some other SO questions that seem related but I've not been able to make them work.
I have 3 layers. header, menu, body. The real application is much more complicated, of course. But for the sake of this question this is sufficient enough data.
The entire page itself fills 100% width, but the content within each section will be fixed to 1024px wide. This was easily done with the reknown margin: 0 auto; style. So that wasn't an issue.
Here is the trick. The middle layer, the menu. I want the menu to overlap the border between the header and the content. Now then, doing this was also not too hard. I just absolutely position the menu and kick it down by 100px to get it to the right vertical alignment.
What I cannot seem to achieve is the horizontal alignment of the 1024px block. I've included a light fiddle and an image of the expected output (beware, jsfiddle's default preview pane is not 1024px wide, so it looks like it is working at first glance)
Update
Following the instructions at this post I was able to make it work. But it is only functioning in Chrome.
http://jsfiddle.net/dE8xE/
Desired Output (colors exaggerated for emphasis and distinction)
#site-menu {
background-color: #fff;
height: 64px;
position: absolute;
top: 100px;
display: block;
width: 1024px;
/* everything is easy when you have fixed width */
left: 50%;
margin-left: -512px;
}
Can you use percentage margins and width to achieve the effect you're going for? Setting the z-index to something greater than those of the other sections will get it to float over them. Example: http://jsfiddle.net/6xCfU/
margin: 10% 0 0 10%;
width: 80%;
z-index; 100;
Can you please go to: http://www.binarymark.com/Products/ColorPickerPro/default.aspx and note the page's layout.
What I want to do is to stick or "glue" some small div to the right side of the page, that is so that it's just outside of the right frame of the page.
However, vertically I want the div to be fixed to a Window, that is no matter how much the page is scrolled, it should remain a fixed 300px from the top edge of the window.
Here's what it should look like http://www.binarymark.com/layexp.png
Can you help me please?
Seems easy, but I have no idea how to combine vertical fixed positioning and horizontal relative/absolute positioning and making sure it supports all major browsers.
Thanks.
position: fixed;
right: 0;
top: 50%;
Edit: try inserting this div as the first child of your <div id="content">...
<div class="right-tab">TEXT</div>
CSS:
.right-tab {
position: fixed;
top: 50%;
width: 1100px;
background-color: red;
text-align: right;
}
That should get you started. The width will specify how much past the content you want your tab to show (so in this case it's about 100 px). The red background is just so you can more easily see the div.
