css position absolute off center to the left - css

I'm trying to position a div box off center and to the left. It must be absolute positioning and I can't wrap it within another div as it's generated by a very long js script.
Here's my css so far:
.nivo-html-caption {
position:absolute;
top:59px;
opacity:0.8;
transition:all 0.8s ease-out;
background-color: rgba(0,0,0,0.24);
width: 350px;
color: #cbcbcb;
padding: 10px;
margin:auto;
}
I'm using the margin:auto; to center it and the top:59px; to push it down from the top. But I now need to push it off center to the left about 300px.
I'm not quite sure how to do this without wrapping it in another div or putting another div inside it (which I really don't want to start doing as it's going to take a lot of messing around)

Your request is a little unclear but you first need to center the item and then move it over 50% of the required adjustment.
.nivo-html-caption {
position:absolute;
top:59px;
left:50%;
transform:translateX(-50%); /* centered first regardless of width*/
margin-left: -175px; /* then moved over */
.parent {
position: relative;
height: 500px;
border:1px solid green;
}
.nivo-html-caption {
position:absolute;
top:59px;
left:50%;
transform:translateX(-50%);
margin-left: -175px;
opacity:0.8;
transition:all 0.8s ease-out;
background-color: rgba(0, 0, 0, 0.24);
width: 350px;
color: #cbcbcb;
padding: 10px;
}
.center {
position: absolute;
top:0%;
left:50%;
height: 100%;
width: 1px;
background: red;
}
<div class="parent">
<div class="nivo-html-caption"></div>
<div class="center"></div>
</div>

As it's positioned absolute, instead of centering it using margin: auto, try this:
left: 50%;
margin-left: -175px;
This will centre it and adjusting the margin-left will take it off centre.

margin: 0 auto will not get you the right results if position is set to absolute, so try:
left: 50%;

position: absolute;
margin: auto;
top: 0px;
this will make the div stick to the left side. and vertically center
example fiddle here

try like this : Demo
h1 {
position:absolute;
top:59px;
opacity:0.8;
transition:all 0.8s ease-out;
background-color: rgba(0, 0, 0, 0.24);
width: 350px;
color: #cbcbcb;
padding: 10px;
margin:auto;
left: 50%;
margin-left: -25%;
}
HTML:
<h1> Text half center </h1>
I tried to align it in center using left and shifted half using margin-left

CSS custom colored border

I want to create a top-right border of a div like the following picture
I am pretty new to css. Could anyone give me a pointer to this?
You can use an absolutely positioned ::after pseudo element ( or an element in your markup ) to create the green area. Setting the upper right border radius and overflow: hidden; will finish the job.
body {
background: #ddd;
}
div {
background: white;
width: 100px;
height: 50px;
}
.funky-border {
border-top-right-radius: 30px;
position: relative;
overflow: hidden;
}
.funky-border:after {
content:'';
background: green;
width: 20px;
height: 60px;
transform: rotate( 135deg );
position: absolute;
top: -20px;
right: 0;
}
<div class="funky-border"></div>
Here is an easy way with one element:
.box {
width:200px;
height:100px;
border-top-right-radius:30px;
background:
linear-gradient(to top right,transparent 49%,green 50%) top right/50px 50px no-repeat,
gray;
}
<div class="box">
</div>

css transparent shape over image

This is what i am trying to achive
i have :
#image1 {
position: absolute;
bottom: 0px;
align-self: auto;
background-color: #dc022e;
width: 340px;
height: 100px;
border-radius: 50% / 100%;
border-bottom-left-radius: 0;
/*transform: rotate(10deg);*/
border-bottom-right-radius: 0;
opacity: 0.8;
}
#image2 img {
width: 80%;
}
<div>
<div id="image2">
<img src="http://t1.gstatic.com/images?q=tbn:ANd9GcThtVuIQ7CBYssbdwtzZjVLI_uw09SeLmyrxaRQEngnQAked5ZB">
</div>
<div id="image1"></div>
</div>
Finally I don't know how to make it rotated and with the margins cut like in the picture
A Quick example of this would use a pseudo element and have the image set in the background.
div {
position: relative;
height: 300px;
width: 500px;
background: url(http://lorempixel.com/500/300);/*image path*/
overflow: hidden;/*hides the rest of the circle*/
}
div:before {
content: "";
position: absolute; /*positions with reference to div*/
top: 100%;
left: 50%;
width: 0;/*define value if you didn't want hover*/
height: 0;
border-radius: 50%;
background: tomato;/*could be rgba value (you can remove opacity then)*/
opacity: 0.5;
transform: translate(-50%, -50%);/*ensures it is in center of image*/
transition: all 0.4s;
}
/*Demo Only*/
div:hover:before {/*place this in your pseudo declaration to remove the hover*/
height: 100%;
width: 150%;/*this makes the shape wider than square*/
transform: translate(-50%, -50%) rotate(5deg);/*ensures it is in center of image + rotates*/
}
div {/*This stuff is for the text*/
font-size: 40px;
line-height: 300px;
text-align: center;
}
<div>HOVER ME</div>
Instead of nested elements, you can just use a pseudo element. This is placed at the bottom of the container div. For this to work, you need position:relative and overflow:hidden on the container div. Also, pseudo elements always need the content declaration.
To modify the border radius, you just play around with left | width | height of the pseudo element. You don't need any rotation.
Instead of hex color and opacity you can as well use the "new" color space rgba(r,g,b,a) where a is the opacity value.
For the passepartout you simply use the border declaration.
#image2{
position:relative;
border:10px solid #888;
overflow:hidden;
box-shadow:0 0 4px #aaa;
}
#image2::after {
content:"";
display:block;
position: absolute;
bottom: 0;left:-10%;
background-color: #dc022e;
width: 120%;
height: 60%;
border-radius: 100% 100% 0 0;
opacity: 0.8;
}
#image2 img {
width: 100%;
display:block;
position:relative;
}
<div id="image2">
<img src="http://t1.gstatic.com/images?q=tbn:ANd9GcThtVuIQ7CBYssbdwtzZjVLI_uw09SeLmyrxaRQEngnQAked5ZB">
</div>
You can just use position: absolute for your image and position: relative for your overlay, adjusting the top position and width according to your needs. Here's a Fiddle. Hope this helps!
Edit: Here's an updated version of the Fiddle demonstrating border and overflow properties on the img container. As CBroe mentioned, rotating a circle is probably not a good use of your time in this case. Also, I definitely agree that using a pseudo element is a much cleaner approach than nesting images.

Is it possible to create this irregular quadrilateral with CSS?

I've tried the perspective solution here How to transform each side of a shape separately? but can't get it to work probably due to the irregularness of the shape. Only the top and right side columns are slanted, vertical and bottom are straight. How can I do this with CSS?
Using CSS borders you can create triangles and trapezoids.
You can achieve your shape joining a triangle and a trapezoid.
.triangle {
border: 0 solid red;
border-left-width: 500px;
border-top-width: 30px;
border-top-color: transparent;
}
.trapezoid {
border: 0 solid red;
width: 500px;
border-bottom-width: 150px;
border-right-width: 30px;
border-right-color: transparent;
}
<div class="triangle"></div>
<div class="trapezoid"></div>
Method 1: Clip path
You could make use of CSS clip-path feature to clip a rectangle into the required polygon shape.
div {
box-sizing: border-box;
height: 150px;
width: 250px;
background: red;
padding: 10px;
-webkit-clip-path: polygon(0% 0%, 90% 10%, 100% 100%, 0% 100%);
clip-path: polygon(0% 0%, 90% 10%, 100% 100%, 0% 100%);
}
div#image {
background: url(http://lorempixel.com/400/200);
}
/* Just for demo */
div{
float: left;
margin: 10px;
transition: all 1s;
}
div:hover{
height: 200px;
width: 300px;
}
<div>Some text</div>
<div id="image"></div>
Pros:
Supports non-solid color fills inside the shape and also allow text to be present inside.
The shape is responsive and can adapt even if the container's dimensions change.
Cons:
Poor browser support for the CSS clip-path feature. This can be overcome by using inline SVG for the clip-path like in the below snippet as this has much better browser support.
div {
box-sizing: border-box;
height: 150px;
width: 250px;
padding: 10px;
background: red;
-webkit-clip-path: url(#clip);
clip-path: url(#clip);
}
div#image {
background: url(http://lorempixel.com/400/200);
}
/* Just for demo */
div{
float: left;
margin: 10px;
transition: all 1s;
}
div:hover{
height: 200px;
width: 300px;
}
<svg width="0" height="0">
<defs>
<clipPath id="clip" clipPathUnits="objectBoundingBox">
<path d="M0 0, 0.9 0.1, 1 1, 0 1z" />
</clipPath>
</defs>
</svg>
<div>
Some text
</div>
<div id="image"></div>
Method 2: CSS Transforms
Generally it is better not to use transforms when there is going to be content like image or text inside the shape (or) when the shape's background is not going to be a solid color because then we would either have to (a) reverse transform the child elements separately to make them look normal or (b) use absolute positioning.
For this particular shape, having text inside the shape is not a problem even while using transforms but having non solid background colors would be.
Option 1: Using two pseudo-elements
You could use a couple of pseudo-elements with skew transforms, position one on the top and the other on the right to produce the required shape. Hover the shape in snippet to see how it is created.
div {
position: relative;
height: 150px;
width: 250px;
background: red;
margin: 40px 40px 0px 0px;
}
div:after,
div:before {
position: absolute;
content: '';
background: red;
z-index: -1;
backface-visibility: hidden;
}
div:before {
height: 12.5%;
width: 100%;
top: 0px;
left: 0px;
transform-origin: right top;
transform: skewY(3deg);
}
div:after {
height: 100%;
width: 12.5%;
right: -1px;
top: -1px;
transform-origin: right top;
transform: skewX(10deg);
}
/* Just for demo */
div{
transition: all 1s;
}
div:hover{
height: 250px;
width: 300px;
}
div:hover:after{
background: blue;
}
div:hover:before{
background: green;
}
<div>Some text</div>
Pros:
Shape can be created with a single element and can have text inside it without any trouble.
Cons:
Having gradients (or) images as background for the shape is complex because they would need reverse rotation as mentioned earlier.
Shape is not 100% scalable as dimensions of the container should change proportionately for the shape to be maintained (hover on the shape in the snippet to see what I mean). Reason is same as mentioned here.
Option 2: Using one pseudo-element
This is pretty similar to the previous option except that this uses a single pseudo-element along with a overflow: hidden on the parent.
div {
position: relative;
box-sizing: border-box;
height: 200px;
width: 300px;
padding: 10px;
overflow: hidden;
}
div:after {
position: absolute;
content: '';
top: 0px;
left: -20px;
height: 100%;
width: 100%;
background: red;
transform-origin: left bottom;
transform: skewY(5deg) skewX(7.5deg);
z-index: -1;
}
div:hover {
height: 300px;
width: 500px;
transition: all 1s;
}
<div>Some text</div>
Pros:
Shape can be created with a single element and can have text inside it without any trouble.
Shape is responsive and can adapt even if the container's dimensions change .
Cons:
Same constraint as the previous option for gradient and image backgrounds.
Not suitable if the overflow: hidden on the parent is a constraint.
A solution is:
div {
width: 300px;
height: 100px;
margin:50px;
background-color: yellow;
border: 1px solid black;
}
.thisdiv {
-ms-transform: skewX(-20deg); /* IE 9 */
-webkit-transform: skewX(-20deg); /* Safari */
transform: skewX(-20deg); /* Standard syntax */
}
<div class="thisdiv">
This is the div I will skew
</div>
This is how to skew an element, if you want to make the shape you added, try using two overlaping div's, position, scale, rotate and skew, like this:
.outer-div{
position:relative;
margin:50px;
width:200px;
height:200px;
border:2px black dashed;
}
.inner-one{
position:absolute;
left:0;
bottom:0;
width:180px;
height:180px;
background:red;
}
.inner-two{
position:absolute;
bottom:2px;
right:0px;
width:200px;
height:195px;
background:red;
transform: rotate(7deg) skew(14deg) scale(0.905); /* Standard syntax */
}
<div class="outer-div">
<div class="inner-one">
</div>
<div class="inner-two">
</div>
</div>
2 Triangle Solution for Irregular Quadrilateral in CSS
In looking at your image, I notice that the skew at the top and right are really just long, narrow triangles overlaying the rectangle.
So what I did was create triangles using CSS border properties and absolutely position them over the rectangle.
#rectangle {
width: 400px;
height: 200px;
background-color: red;
margin-top: 25px;
position: relative;
}
#triangle-down {
border-left: 30px solid red;
border-right: 0;
border-top: 200px solid transparent;
position: absolute;
right: -30px;
top: 0;
}
#triangle-left {
border-top: 0;
border-bottom: 15px solid red;
border-right: 400px solid transparent;
position: absolute;
right: 0;
top: -15px;
}
<div id="rectangle">
<div id="triangle-down"></div>
<div id="triangle-left"></div>
</div>
jsFiddle demo
You could check out the clip-path property (see below from MDN), but support is very patchy. Chrome 24+ supports with prefix and FF, but only URL values, which reference a path in an SVG. You can read more about clip-path here.
Here's a basic pen - this will only work in Chrome.
From MDN
The clip-path CSS property prevents a portion of an element from getting displayed by defining a clipping region to be displayed i.e, only a specific region of the element is displayed. The clipping region is a path specified as a URL referencing an inline or external SVG, or shape method such as circle(). The clip-path property replaces the now deprecated clip property.

How to align a div element using the center of the page as a reference?

So I'm trying to get an element to align itself a certain percentage from the CENTER of the page.
So I've tried replacing where I'd usually put a percentage from either the left or the right with "center"
.aboutcredit {
z-index:-100000;
center:25%;
top:75%;
transform:translateY(-50%) translateX(-50%);
position:fixed;
text-align:center;
vertical-align:middle;
}
but no luck. Kind of what I'm trying to do here:
I don't know if you have noticed, but center:25%; does nothing. You probably want left:50%. Seeing as you want it to be moved 25%, make it left:75%; and that should be what you're looking for. Like so:
.aboutcredit {
width: 50px;
height: 50px;
background-color: black;
z-index: 1;
position: absolute;
left: 75%;
top: 50%;
transform: translate(-50%);
text-align: center;
vertical-align: middle;
}
<div class="aboutcredit"></div>
I've run into this several times, and the way I do it is to:
1. Set the element to position absolute
2. set the element using percentages to the area where you would like it, to center on page it would be left:50%, margin-left: -{width / 2}, but in this case it is left:75%, margin-left: -{width / 2}
.box {
height:400px;
width:400px;
border:1px solid black;
left: 75%;
margin-left:-200px;
position: absolute;
}

Overlapping divs on :hover

I have divs that grow heightwise on hover and on hover I want them overlap all other divs, and not push them like in my example.
#container{

}
#container a div{
float:left;
width: 100px;
height: 60px;
-webkit-transition: all 0.25s ease;
}
#container .color1{

#container .color2{

#container .color3{
background: #666;
}
#container .color4{
background: #777;
}
#container .color5{
background: #888;
}
#container a div:hover{
height: 80px;
-webkit-transition: all 0.25s ease;
}

You can make some divs that act like rows for each three divs and set it with position:absolute and z-index.
Check this link http://jsfiddle.net/5wa3X/5/
If they're all going to have fixed dimensions like in your example, position them all absolutely inside a container with position relative; this takes them out of the flow and they won't push any other content.
Well the obvious answer would be for you to use position: absolute for the container, and then position: relative with each one of those divs, so they don't affect each other's positions with the box-model. But that would mean for you to manually position them (each one) so they look like they're stacked...
But maybe there's a way around it using z-index. It would make sense that by sending the container to a lower z-index and allowing overflow, that the children would somehow "hold their ground"... but a quick experiment lead me nowhere. Will try to play with it more later :)
You should use position: absolute with some positioning classes.
