CSS position absolute doesn't work in IE7 - html

i have the following simple script, but it doesn't work in IE7
<div id="content">
<div id="left"></div>
<div id="right"></div>
<div id="bottom_menus">any text here...</div>
</div>
and CSS
#content

}
#bottom_menus
{
background-color: orange;
height: 15px;
position: absolute;
bottom: 0px;
width: 100%;
}
why position absolute doesn't work?
thanks in advance

for absolute position to work, you must specify both direction: eg. top & left, or bottom & rightetc...
For you footer (bottom_menus) to take all space you need to set:
#bottom_menus {
background-color: orange;
height: 15px;
position: absolute;
left: 0;
right: 0; //assuming you need the footer to take the whole width
bottom: 0;
width: 100%;
}
ps: small remark, you dont need to set px unit when value is 0.

You haven't specified a left, so it's defaulting to 0px; Since you have a margin of -5000px on the box, I'm guessing it is working, and the bottom_menus div is off the screen to the left. Absolute positioning would ignore the padding of its parent container. Try setting left: 5000px, assuming you need the negative margin and positive padding. What are you trying to accomplish with that?

Absolutely postioned div moving with margin top of another static postioned div

I have a body containing two div's one is an absolutely positioned div and another one is a static default positioned div, i want the absolutely positioned div to take the full height of the screen which it takes but the problem that next arises is when i try to apply margin top to the statically positioned div, it also gets added to the absolutely positioned div.
How can I make the absolutely positioned div not get the margin of the sibling div ?
body {
font-family: sans-serif;
margin: 0;
padding: 0;
position: relative;
}
.div-1 {
position: absolute;
border: 2px solid red;
width: 90%;
left: 0;
right: 0;
margin: 0 auto;
height: 100vh;
}
.div-2 {
height: 200px;
width: 90%;
background-color: blueviolet;
margin-top: 8rem;
}
<div class="div-1"></div>
<div class="div-2"></div>
The issue is that you have margin collapse on the body element. Margin collapse happens when there's no content separating parent and descendants elements (such as the body and .div-2). You can easily fix this by setting the display property of the body element to flow-root.
body {
font-family: sans-serif;
margin: 0;
padding: 0;
position: relative;
/* Set flow-root */
display: flow-root;
}
.div-1 {
position: absolute;
border: 2px solid red;
width: 90%;
left: 0;
right: 0;
margin: 0 auto;
height: 100vh;
}
.div-2 {
height: 200px;
width: 90%;
background-color: blueviolet;
margin-top: 8rem;
}
<div class="div-1"></div>
<div class="div-2"></div>
body {
font-family: sans-serif;
margin: 0;
padding: 0;
position: relative;
}
.div-1 {
position: absolute;
border: 2px solid red;
width: 90%;
left: 0;
right: 0;
margin: 0 auto;
height: 100vh;
z-index:1;
}
.div-2 {
height: 200px;
width: 90%;
background-color: blueviolet;
top: 8rem;
position: inherit;
}
Use top and position inherit instead of margin-top, check if it can be use.

Centering a div, margin: 0 auto; not working

After searching to center my div all I could get was margin: 0 auto; together with an assigned width, but still it not working.
My problem is simply centering a div. I have no idea why margin: 0 auto; isn't working.
Here is the layout of my CSS/html:
CSS
.countdown-box {
position: absolute;
width: 80px;
margin: 0 auto;
height: 130px;
/*left: 50%;*/
background: #008040;
border-radius: 4px;
z-index: 2;
}
<div class="countdown-box"></div>
It's because you are using position: absolute;. Change it to position: relative; and it will work.
The margin: auto works with elements with relative position. To center with absolute position should be like the following CSS:
.countdown-box {
position: absolute;
background: #008040;
border-radius: 4px;
height: 130px;
width: 80px;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;
}
<div class="countdown-box"></div>
Actually margin auto will allocate the available space, which means it doesn't has any relation with it is relative or not.
<div class="centerize"></div>
.centerize {
width: 200px;
height: 200px;
margin: 0 auto;
background: yellow;
}

Centered divs with overall border

Take a look at this fiddle: https://jsfiddle.net/hkbynkmf/1/
How do I let the green border flow around all the divs, with no div "overflowing" the border? The upper div is OK, but the lower one is not.
Also, I need some distance between the divs;
I know that padding and margin is transparent, so I chose (a green) border to illustrate my point. In the end, the clearance should be transparent.
HTML:
body {
position: relative;
background-color: #ff0000;
background-repeat: no-repeat;
background-attachment: fixed;
padding: 0px;
border: 10px solid #190;
margin: 0px;
}
#header {
position: relative;
margin:0 auto; /* div will be H-centered */
top: 10px;
left: 0px;
bottom: 0px;
right: 0px;
width: 960px;
height: 250px;
background-color: #DDDDDD;
overflow: hidden; /* Keep all sub-elements inside this div */
}
#intro {
position: relative;
margin:0 auto; /* div will be H-centered */
top: 15px;
left: 0;
bottom: 0px;
right: 0px;
width: 960px;
height: 150px;
background-color: blue;
overflow: hidden; /* Keep all sub-elements inside this div */
}
<body> <!--position: relative;-->
<div id="header"> <!--position: relative;-->
</div>
<div id="intro"> <!--position: relative;-->
</div>
</body>
You're using the top attribute to move your intro div 15px down, below the header. This is causing the 15px overlap with the container. When positioning items this way you should consider using margin to apply the change, rather than the positioning attributes of top, right, bottom or left.
You have a lot going on with your CSS which is making the stylesheet much more complicated than it needs to be. I have simplified your CSS as follows to achieve the same effect:
body {
background-color: #ff0000;
border: 10px solid #190;
margin: 0px;
padding: 0px;
}
a img {
border:none;
}
#header {
background-color: #DDDDDD;
height: 250px;
margin:0 auto;
overflow: hidden;
width: 300px;
}
#intro {
background-color: blue;
height: 150px;
margin:15px auto 0;
overflow: hidden;
width: 300px;
}
See updated fiddle
In your code, the #intro is positioned 15px below the #header. Doing so leaves no place for the div in body.
Not sure what you are trying to achieve here with position: relative; but the #intro can be written like
#intro
{
margin:10px auto;/* div will be H-centered */
width: 300px;
height: 150px;
background-color: blue;
overflow: hidden;/* Keep all sub-elements inside this div */
}
Using the margin top property on the #intro div will allow the green border to flow, while also having the space in between the divs. Here is the fiddle:
https://jsfiddle.net/hkbynkmf/17/
#intro
{
position: relative;
margin:15px auto 0px auto /* div will be H-centered */
left: 0;
bottom: 0px;
right: 0px;
width: 300px;
height: 150px;
background-color: blue;
overflow: hidden; /* Keep all sub-elements inside this div */
}

Stretch fixed to bottom parent div to div child's width

So, I have a main container that shows like the following:
I want to be able to adapt the parent div to the number of child's it receives. Let's say we remove div2. The result should be something like this:
Instead, the parent div does not stretch to the width of the div child's
Here's my code:
HTML:
<div class="main-container">
<!-- Card container -->
<div class="card-container">
<div class="card">div1</div>
<div class="card">div2</div>
<div class="card">div3</div>
</div>
<!-- Footer container -->
<div class="footer">i am a footer</div>
</div>
CSS:
.main-container {
position: fixed;
margin: 0 auto;
left: 0;
right: 0;
bottom: 0;
width: 100%;
max-width: 400px;
box-shadow: 0 0 15px #B3B3B3;
border-top-left-radius: 3px;
border-top-right-radius: 3px;
text-align:center;
}
.card-container {
color: #3B3D3D;
height:105px;
float: left;
width: 100%;
}
.footer {
color: #FFFFFF;
background: #0095D3;
height: 45px;
float: left;
width: 100%;
}
.card {
width:100px;
float:left;
}
What am I doing wrong here? I've tried the display: inline-block; solutions out there but since the parent div must be fixed to the bottom, I am not seeing the desired result.
Any help will be precious.
Thanks in advance.
Try this https://jsfiddle.net/2Lzo9vfc/136/
You can try to remove one .card on click and see what hapens here https://jsfiddle.net/2Lzo9vfc/138/
CSS
.main-container {

}
.card {
width:100px;
height:105px;
display: inline-block;
}
HTML
<div class="main-container">
<div class="card">div1</div>
<div class="card">div2</div>
<div class="card">div3</div>
<div class="footer">i am a footer</div>
</div>
Here you go: http://codepen.io/n3ptun3/pen/PPgWNb
You don't need to use display: inline-block.
I've left your HTML alone, and simplified some of your CSS: .card-container and .footer don't need float: left; and width: 100%;. They are both block-level elements so they will take up 100% of the width, and they don't need anything to wrap around them.
On the .main-container, you can't set margin: 0 auto; and position: fixed;. position: fixed; removes the ability for centering via margin. left: 0; and right: 0; were stretching the size of the main container, so those need to be removed. width: 100%; and max-width: 400px; were trying to fix the width issue, but that wouldn't allow resizing based on content.
Instead you need to set left: 50%; (places left edge of element at 50% of the parent's width, i.e. the viewport width, in this case) and then transform: translate(-50%); to bring the element back toward the left by 50% of its width. Thus bringing the element to the center of the window/viewport.
Now, if you remove one of the "cards," it will resize the "main-container," while keeping everything fixed to the bottom and centered.
.main-container {
position: fixed;
bottom: 0;
left: 50%;
transform: translate(-50%);
box-shadow: 0 0 15px #B3B3B3;
border-top-left-radius: 3px;
border-top-right-radius: 3px;
text-align: center;
}
.card-container {
color: #3B3D3D;
height: 105px;
}
.card {
width: 100px;
float: left;
}
.footer {
color: #FFFFFF;
background: #0095D3;
height: 45px;
}
EDIT: Based on your new information (re: the increased width or added "cards"), I've found that the issue lies with the left position on the .main-container. When you position the element by 50% and its width is more than 50% of the parent, it runs into the right side of the parent div, and you get the stacking. To fix this, you can instead remove the float: left; on .card and add display: flex; on .card-container. This will allow you to increase the width of the "cards" while keeping them from stacking.
I've updated the code here: http://codepen.io/n3ptun3/pen/PPgWNb
.main-container {
position: fixed;
bottom: 0;
left: 50%;
transform: translate(-50%);
box-shadow: 0 0 15px #B3B3B3;
border-top-left-radius: 3px;
border-top-right-radius: 3px;
text-align: center;
}
.card-container {
color: #3B3D3D;
height: 105px;
display: flex;
}
.card {
width: 100px;
// float: left;
}
.footer {
color: #FFFFFF;
background: #0095D3;
height: 45px;

Issue with centering while keeping header in fixed position

I have a problem centering everything while keeping my header in fixed position. Can anyone help me figure out why?
Here is my HTML
<div id="wrapper">
<div class="header">....</div>
<div class="experiences">...</div>
</div>
Here is the CSS:
#wrapper {
margin: 0 auto 0 auto;
width: 1000px;
height: auto;
}
.header {
background-color: #222;
color: white;
top: 0;
left: 0;
right: 0;
position: fixed;
height: 130px;
padding: 20px;
width: 1000px;
margin: 0 auto 0 auto;
}
.experiences {
background-color: #eee;
padding: 20px;
* padding-top: 190px;
width: 1000px;
margin-top: 170px;
}
You just need to remove the left and right declarations in .header.
The rest should already be centered (unless you use a very old version of IE...).
