Using CSS to emulate tabbed windows - html

I currently have two divs that I'm trying to use to emulate a drop down tabbed window.
I have content where the grayed out areas are. The bigger div (the div containing the big gray area or the "window") has a position of absolute, but so does the little div (the tab). I can't figure out how to move the tab so that I can add more tabs. When I do add more tabs, they just sit over the middle tab. I've looked at all the styling in the Elements dev tools, but there aren't other properties that can "shift" the tab left or right. How can I move it over to the left by, say, 200 px?

It is hard to help you without knowing more about your situation and seeing the code. But I made a couple illustrations to try and help you.
Example one.
This is how I would do it without position absolute. This way will keep the content area up top but will stack the tabs from left to right as you add more,
html
<div id="content">
</div>
<div id="tab1" class="tab">
</div>
<div id="tab2" class="tab">
</div>
<div id="tab3" class="tab">
</div>
css
#content {
background-color: gray;
width: 100%;
height: 200px;
}
.tab {
width: 100px;
background-color: gray;
height: 50px;
display: inline-block;
}
Output
This way is using position absolute and here is a jsfiddle.
Once an element has position absolute it can be moved around with directional rules. It starts in the top left corner. To move it now you can add a direction with an amount.
#myElement: {
position: absolute;
top: 20px;
right: 50px;
bottom: 20px;
left: 10px;
}
You can play with these values and watch the element move around the window.
Same html as example 1.
CSS
#content {
background-color: gray;
width: 100%;
height: 200px;
}
.tab {
width: 100px;
background-color: gray;
height: 50px;
display: inline-block;
}
#tab1 {
position: absolute;
left: 8px;
}
#tab2 {
position: absolute;
left: 300px;
}
#tab3 {
position: absolute;
left: 631px;
}
If this does not help you please add your code so I can better understand what you are trying to accomplish. From your question it sounds like you are having trouble using position asbsolute and creating tabs side by side of eachoter under the content. If so I have provided two examples.
1. using position absolute.
2. using display: inline-block.

image appears when hover over text

I'm not super comfortable with JS , but that seems to be the best way to do this , having a hard time applying other peoples solutions to my scenario.
Want an image to appear when hover over text.
I can get the image to appear on hover, but it appears up way up at top of page, and I am having a hard time getting it to appear in the viewport without indicating what the top margins is. Is that the best way to do it?
So far I have:
<div id="popup">
<div class="large-6 columns">
Bristol Hayward-Hughes <span> <img src="bristol.jpg" alt="Bristol" id="bristol"> </span>
</div>
</div>
and
#popup span {
display: none;
}
#popup a:hover span {
display: block;
position: absolute;
top: 0px;
left: 170px;
width: 400px;
margin: auto;
}
#bristol {
position: absolute;
z-index: 1;
margin-top: 100px;
}
If I'm understanding the question correctly, you'll need to place position:relative; in the parent Div: #popup that the image is residing in.
Check this Fiddle for reference: https://jsfiddle.net/rjschie/q87um7wd/2/
For an example: comment the position:relative; line under #popup and re-run the example. You'll see that the Image appears at the top of the window. Then uncomment it, and re-run and it will appear relative to the #popup div.
Please give relative positioning to your span that holds your image.
#popup a:hover span {
display: block;
position: relative; // Changed absolute to relative
//Give top and left position with respect to your anchor tag.
top: 0px;
left: 170px;
width: 400px;
margin: auto;
}
Remove the margin-top from the image tag as well.
#bristol {
position: absolute;
z-index: 1;
/*margin-top: 100px;*/ //Removed margin-top on the image
}

Problems with layout css and javascript

I have the following layout:
On the left side I have a menu and big gray part on the right side is the body content. The problem is on the left menu I have a bunch of buttons. I want this menu to be fixed position and body scrollable. I Have the following css:
#menu {
position: fixed;
}
#content {
position: inherit;
margin-left:300px;
}
The problem is that on the red part of my menu all button unavailable, I can't click on it. looks like body overrides the menu.
Any ideas what the problem might be?
Thanks
Including the html would give a better sense of the stacking order and likely yield a better answer. Given what you've provided, this should fix:
#menu {
position: fixed;
z-index: 1;
}
In order to fix it to the top and not scroll, you don't use position: fixed;. You need to use position: absolute;. If you don't want it at the very top, then you use position: relative; and place it inside an element.
Then, in order to scroll, you use position: fixed;.
When you use position: fixed, it places the element fixed within the visible page.
However, when you use position: absolute, what this does is put it on an absolute position on the page regardless of scroll. For example, if you added the css top:0; then it would be 0 pixes from the absolute top of page, and if you scroll down it will disappear from view because it is all the way at the top of the actual page, not just the top of the visible page.
I understand it seems a bit counter-intuitive to you. However, you can see it working in the jsbin below.

CSS: Banner&Menu postions

Short sketch of the situation: I'm making a website (obviously :)) and so I've got my header, then my banner and below the banner i've got my menu bar. However, the banner overlaps my header a bit (that's the intention ;)) and now I want to add the menu bar directly below the banner.
Here's my CSS code:
.header_container{
background-color: #e5e5e5;
height: 200px;
overflow: hidden;
}
.banner {
position: relative;
top: -90px;
background: url(../images/banner.png) no-repeat top center;
height: 210px;
}
.menu {
background: url(../images/menubalk.png) no-repeat top center;
}
The menubar is at the position where i should be if the banner would not have an overlap.
I have just figured something small out, which would probably fix my entire problem. If I were to make my header a box, and then my main content a box (which holds the banner, content and footer) and make all the different things, like the banner children from that box? wouldn't that fix my entire problem while I use the inherit or whatever function?
Thank you in advance!
Kind regards,
David
One way of doing this has been suggested, use relative positioning for the menu element.
For example:
<div class="header_container">
Le Header Container
</div>
<div class="banner">
Le Banner
</div>
<div class="menu">
Le Menu
</div>
and the CSS would look like:
.header_container{
background-color: #e5e5e5;
height: 200px;
overflow: hidden;
}
.banner {
background-color: yellow;
position: relative;
top: -90px;
height: 210px;
}
.menu {
background-color: red;
position: relative;
top: -90px;
height: 50px;
}
As a start, here is a fiddle: http://jsfiddle.net/audetwebdesign/9gvTG/
Alternative Method
You can achieve a similar effect by using a negative margin:
.header_container{
background-color: #e5e5e5;
height: 200px;
overflow: hidden;
margin-bottom: -90px; // only need to adjust this property
}
.banner {
background-color: yellow;
position: relative;
height: 210px;
}
.menu {
background-color: red;
position: relative;
height: 50px;
}
The advantage of this approach is that the positioning of the subsequent elements do not need adjusting if you change the header and need to modify the degree of overlap by the banner element.
It is good to be aware of both approaches.
One solution in your case would be to position your menu absolute at bottom:-120px. It's not the most elegant one but it should work.
You should assign a relative position to your menu as well. With same top value as the banner
.menu {
....
....
position: relative;
top:-90px;
}
The space you see is because the menu, in normal document flow, is positioned just below the place the banner is located. (which is shifted 90px up from its real position)
A fiddle here
Instead of your images I used background color
You can place the menu just at the bottom of your banner or where ever you need.
Then remember that element that follows the menu will see the menu in his real position . In this case 90px below.Many solutions to wrap all this issue so wont affect the rest of the page elements.

Position the center of an image using css

let's say I have to place an image RIGHT in a proper spot, but I need its CENTER to be in that spot. I wanted to place an image in the top-left corner of a div, so I placed the image in the div, gave position: relative to the div and position: absolute to the image then set its top and left values to 0. It quite worked but I'd need the CENTER of that image to be right over the top left corner. I'd do it manually setting top: -xpx, left: -ypx BUT I don't have any specific value for the image size (which could vary a lot).
So is there any way to say something like: position: absolute-but-i'm-talking-about-the-center; top: 0px; left: 0px;?
Thank you very much indeed!

You could use javascript yo get the size of the image and then set the css left value needed.
Be mindful of the way images are loaded though as they are asynchronous so will not necesserily be available when the document is ready. This means that unless you handle the images correctly you will end up with width and height dimensions of 0.
You should wrap the image in another block element and put a negative left position to the image.
Something like this:
<div id="something">
<div class="imagewrap">
<img>
</div>
</div>
Then give #something a relative position, .imagewrap an absolute, etc... And img should have a relative position with left:-50%. Same for the top.
have you tried;
name_of_div_with_image {
display: block;
margin-left: auto;
margin-right: auto }
give that a go.
No need to use Javascript, this can be done in CSS.
The required HTML: (you must change the div to an img obviously)
<div id="container">
<div id="imgwrapper">
<div id="img">Change this div-tag to an img-tag</div>
</div>
</div>
The required CSS:
#container
{
position: absolute;
left: 200px;
top: 100px;
height: auto;
overflow: visible;
border: 2px dashed green;
}
#imgwrapper
{
position: relative;
margin-left: -50%;
margin-top: -50%;
padding-top: 25%;
border: 2px dashed blue;
}
#img
{
display: block;
width: 200px;
height: 100px;
border: 2px solid red;
}

The margin-left: 50%; obviously works when using the container div, because the width of the container will be exactly that of the content. (You might need to add width: auto;)
But margin-top: -50%; will not work because the height of the container div will change with it, thus you need yet another wrapper div in which you use this margin-top: -50%; and then you need to fix this error it makes by using a positive percentage based padding. Obviously there may be other solutions to fix this, but the solution should be something like this.
Probably one of the simplest solutions is to place the image in the upper left corner at position
left: 0px; top: 0px; and then use translate to move its center to this position. Here's a working snippet for that:
#theDiv {
position: absolute;
left: 100px;
top: 100px;
background: yellow;
width: 200px;
height: 200px;
}
#theImage {
background: green;
position: absolute;
left: 0px;
top: 0px;
transform: translate(-50%, -50%);
}
<div id="theDiv">
<image width=31.41 height=41.31 id="theImage"></image>
</div>

Navigation bar with two sides

recently I have tried to achieve a navigation bar that has two sides, one on the right and one of the left, they are separated (not same div). I have managed to get the two navigation bars to work but my problem is that when the browser window is smaller then the wrapper (1000px) the right side of the navigation bar will not stick to the right side instead it will be somewhere in the center.
My code until now
css
div.wrapper
{
min-width: 1000px;
}
div.menul
{
float: left;
width: 880px;
padding: 15px;
background-color: red;
}
div.menur
{
position: absolute;
right: 0;
z-index: 999;
width: 250px;
padding: 15px;
background-color: yellow;
}
html
<div class="wrapper">
<div class="menul">
menu
</div>
<div class="menur">
menu
</div>
</div>
help would be appreciated, thank you
Simply add position: relative to the #wrapper CSS. This will cause the right menu to be positioned relative to the #wrapper rather than the page itself
