Center position fixed horizontally - html

I want to dynamically append to the end of the body a fixed-positioned to the bottom box that has 1000px width and is centered horizontally.
When I create it with percentage width I can easily add margins and everything is ok, but when I have it in pixels I can't add margins anymore (it has to be responsive). auto doesn't work either.
How can I do that?
<div style="position: fixed; bottom: 0; width: 1000px; margin: 0 auto; padding: 0;height: 100px; background-color: green;">
</div>

Try this also:
div{
position: fixed;
bottom: 0;
width: 1000px;
left: 50%;
transform:translateX(-50%);
height: 100px;
background-color: green;
}

body:after {
content:"";
width: 1000px;
height: 100px;
position: fixed;
left: 50%;
bottom:0;
margin-left: -500px;
background-color:green;
}

Try this:
div{
position: fixed;
bottom: 0;
width: 1000px;
left: 50%;
margin-left: -500px;
height: 100px;
background-color: green;
}
<div>
</div>

Try CSS3, to avoid giving calculated values in pixel for your margins.
left:50%;
transform: translateX(-50%);

I'm trying to remove the scroll from the page, I do not understand what I'm doing wrong

I want the page to look like the second image.I thought that with the overflow it would be enough to hide the rest of the image
This is the result:
This is what I want
.bgMentor{
height: 100%;
width: 100%;
overflow:hidden;
position:absolute;
}
.bgMentor img{
min-width: 100%;
min-height: 100%;
position: absolute;
top:50%;
left: 50%;
transform: translate(-50%,-50%);
width: auto;
height: auto;
}
<div class="bgMentor">
<img class="img-responsive" src="{{Storage::url('img/getamentor.png')}}">
</div>
Try adding a top and left value for your position: absolute element
.bgMentor{
height: 100%;
width: 100%;
overflow:hidden;
position:absolute;
top: 0;
left: 0;
}
Try using overflow-y: hidden; instead of just overflow:;. If that doesn’t work, try putting the <Img> directly in the body and stylize it using a class=“bgMentor”.

Center an overflowing image

I'm trying to make an image that overflows on it its parent div, but that's centered according to its parent.
Heres how I'd like it to look:
This is the code I currently have but obviously doesn't work,
.wrapper{
height:150px;
width:150px;
position:relative;
background:red;
margin:5em auto;
}
.image{
width:175%;
height:auto;
position:absolute;
}
body{
background:purple;
}
<div class="wrapper">
<img class="image" src="https://pngimg.com/uploads/goat/goat_PNG13151.png">
</div>

I want to achieve this in pure css, no use of javascript.
You can center your image with the "negative translate" trick.
Here's a working example:
.wrapper {
height: 150px;
width: 150px;
position: relative;
background: red;
margin: 5em auto;
}
.image {
width: 175%;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
body {
background: purple;
}
<div class="wrapper">
<img class="image" src="https://pngimg.com/uploads/goat/goat_PNG13151.png">
</div>
Based on this question.
.wrapper{
height:150px;
width:150px;
position:relative;
background:red;
margin:5em auto;
}
.image{
width:175%;
height:auto;
position: absolute;
top: -9999px;
bottom: -9999px;
left: -9999px;
right: -9999px;
margin: auto;
}
body{
background:purple;
}
Try this:
.image{
width:175%;
height:auto;
position: absolute;
top: -9999px;
bottom: -9999px;
left: -9999px;
right: -9999px;
margin: auto;
}
It should center your <img> no matter the size of the parent div
Oh looks like I'm late to this party, but I was going to suggest this technique - using the ::after pseudo element to draw your square underlay and don't actually make the image overflow the wrapper div.
https://codepen.io/hamzatayeb/pen/QMxJvw
<div class="wrapper">
<img class="image" src="http://pngimg.com/uploads/goat/goat_PNG13151.png">
</div>
Then this CSS -
.wrapper {
width: 262px;
height: 262px;
position: relative;
margin: 5em auto;
}
.wrapper::after {
content: "";
background: red;
position: absolute;
top: 16%; right: 16%; bottom: 16%; left: 16%;
z-index: -1;
}
.image {
padding-top: 25px;
width: 100%;
height: auto;
}
body {
background: purple;
}
Try this add this style only to your image
.image{
width:175%;
height:auto;
position:absolute;
top: -18px;
right: -65px;
}

I don't know what do I wrong, so many people tried to help me + I searched for it but I didn't find anything. Here's the code:
HTML:
<div id="parent">
<div id="left"></div>
<div id="right"></div>
<div id="center"></div>
</div>
CSS:
#parent
{
margin-left: 5%;
margin-right: 5%;
position: fixed;
top: 50px;
bottom: 50px;
left: 0;
right: 0;
overflow: auto;
}
#left {
position: relative;
width: 370px;
height: 100%;
float: left;
background: #093F5C;
overflow: hidden;
}
#right {
position: relative;
width: 230px;
height: 100%;
float: right;
background: #093F5C;
overflow: auto;
}
#center {
height: 100%;
min-width: 550px;
overflow: auto;
}
maybe...
#left {
position: absolute;
left:0px;
top: 0px;
width: 370px;
height: 100%;
background: #093F5C;
overflow: hidden;
}
#right {
position: absolute;
right:0px;
top:0px;
width: 230px;
height: 100%;
background: #093F5C;
overflow: auto;
}
#center {
height: 100%;
position:absolute;
left: 370px; /*width of leftDiv */
right: 230px; /*width of rightDiv */
top:0px;
/*min-width: 100px;*/
overflow: auto;
background: red;
}
jsfiddle: http://jsfiddle.net/alemarch/35bxtc2z/7/ (i have change the dimension fixed of the left and right div). Is this what you search?
The #center should have a max-width:550px, not a min-width:550px. You'll also probably want to add a width to it as well.
#center {
height:100%;
max-width:550px;
width:100%;
overflow:auto;
}
There's also a lot of other odd things about your CSS in general, but thats beyond the scope of this question... Some things to think about - why does the #parent have a position:fixed ? Why is everything else position:relative ? And why do you have heights of 100% ?

Vertical-align absolute positioned div

I'm fiddling with Jquery Cycle slideshow and trying to add a couple of buttons. I can't seem to align them veritcally without top: #px; tomfoolery; I'd love to just align it to middle of the div vertically.
CSS
#slidecontainer {
margin-left: auto;
margin-right: auto;
position: relative;
width: 800px;
height: 200px;
}
.slidecontrols {
top: 50px;
position: absolute;
z-index: 100;
width: 100%;
}
.slidecontrols a {
background-color: white;
}
.slidecontrols a.next {
position: absolute;
right: 0;
}
.slideshow {
width: 100%;
height: 100%;
}
.bannered {
height: 200px;
width: 800px;
}
HTML
<div id="slidecontainer">
<div class="slideshow" id="slideoptions">
<img src="http://i.imgur.com/ufZ0cxL.jpg" class="bannered" alt="" /></a>
<img src="http://i.imgur.com/RZTrFy4.jpg" class="bannered" alt="" /></a>
</div>
<div class="slidecontrols">
right
left
</div>
</div>
Here's a Fiddle. Adding vertical-align: middle; to .slidecontrols does absolutely nothing.
Here's another option if you don't want to guess or set any pixels:
.slidecontrols {
top: 50%;
position: absolute;
z-index: 100;
width: 100%;
-webkit-transform: translate(0, -50%);
transform: translate(0, -50%);
}
Assuming the height of the controls will be 20px, you could use a top value of 50% and then a negative margin-top value of half the element's height. In this case, -10px.
Example Here
.slidecontrols {
top: 50%;
margin-top: -10px;
position: absolute;
z-index: 100;
width: 100%;
}
Alternatively, if you need a solution for dynamic heights:
Example Here
.slidecontrols {
position:absolute;
top:0; right:0;
bottom:0; left:0;
z-index: 100;
width: 100%;
height:100%;
display:table;
}
.slidecontrols a {
display:table-cell;
vertical-align:middle;
}
Make top : 50% to slidecontrols which will align the links exactly at the center.
.slidecontrols {
top: 50%;
position: absolute;
z-index: 100;
width: 100%;
}
Another posibility if you consider the buttons has 20px height,
top: calc(50% - 10px); // 10px is half of buttons height
This will align it exactly at the center
When you have position: absolute, the vertical align will not work.

Center Div inside a main Div

i created a maze and i want to center an inside div
although i center it with margin: 0 auto; it won't work
(this div shows sad smily face when user enter the wall and lose)
#highlight_lose {
width: 550px;
height:550px;
position: absolute;
display: none;
margin: 0 auto;
}
here is the fiddle link:
http://jsfiddle.net/uqcLn/28/
If you're going to use absolute positioning you need to do it like this:
#highlight_lose {
width: 550px;
height:550px;
position: absolute;
top: 50%;
left: 50%;
margin: -225px 0 0 -225px;
display: none;
}
Edit: you also need to add position:relative; to the main div. Here is an updated fiddle.
http://jsfiddle.net/FragJ/2/
It looks off because you have other elements that aren't exactly centered.
EDIT: As I stated earlier, the smiley didn't look centered because your code is off. The maze really should be inside a div itself. However I was able to eyeball center it simply by playing with the margins.
http://jsfiddle.net/FragJ/4/
To achieve this you'll need to set your css like this:
#main {
position: relative;
width: 550px;
height: 550px;
float: left;
margin-left: 220px;
margin-top: 100px;
background: grey;
overflow: hidden;
}
#highlight_win {
width: 550px;
height: 550px;
position: absolute;
top: 50%;
left: 50%;
display: none;
margin: -180px 0 0 -180px;
}
#highlight_lose {
width: 550px;
height:550px;
position: absolute;
top: 50%;
left: 50%;
margin: -180px 0 0 -180px;
display: none;
}
.outer {
height: 600px;
width: 500px;
background-color: black;
}
.inner {
height: 200px;
width: 200px;
margin: auto;
position: relative;
top: 200px;
background-color: red;
}
markup
<div class="outer">
<div class="inner">
</div>
</div>
The idea is for fixed sized block elements, setting
margin:auto;
fixes horizontal centering
for vertical central alignment the child's top = half the height of the parent - half the height of the child
