I'm creating a card-flip effect using webkit transformations. I have it working as I like in one section, where I have a DIV that rotates around its center axis giving the look of a card that is flipping over.
I now want to add this same effect to a page transition. I'm using the same CSS and HTML structure, but in this case I'm not getting an effect that rotates around a center axis.
Instead, it looks like the transformation is rotating along the y axis anchored to the left of the object rather than the center (so it looks like a door opening, rather than a card flipping).
I've been reading through the spec's but can't figure out which property controls the rotation axis' position. What do I need to add or change with this to get the flip working?
html structure:
<div id="frontbackwrapper">
<div id="front"></div>
<div id="back"></div>
</div>
and the css (.flip is being added via jQuery to start the effect)
#frontbackwrapper {
position: absolute;
-webkit-perspective: 1000;
-webkit-transition-duration: 1s;
-webkit-transform-style: preserve-3d;
-webkit-transition: 1s;
}
#frontbackwrapper.flip {
-webkit-transform: rotateY(180deg);
}
#frontbackwrapper.flip #front,
#frontbackwrapper.flip #back {
-webkit-transform: rotateY(180deg);
-webkit-transition: 1s;
}
#front, #back {
position: absolute;
-webkit-backface-visibility: hidden;
}
#back {
-webkit-transform: rotateY(180deg);
}
Try this on your wrapper
-webkit-transform-origin: 50% 0 0;
Though you may or may not have to have its width explicitly set.

A map that I am building with OpenLayers 3 has some buttons, which may or may not be available depending on some other things. So I want to keep the unavailable buttons hidden, and others will use their space. The available options can change, so sometimes a button may become (in)visible.
There are some tutorials for creating custom controls with OpenLayers 3. The problem is that all samples I have seen use absolute positioning for the controls. One needs to know how many controls will be visible, and hard-code the coordinates in CSS. Or change the coordinates using Javascript. I.e., from the above link:
.rotate-north {
top: 65px;
left: .5em;
}
I have tried just setting the element with position:relative, but then they appear below the map, as the controls are added to the page after the map. So, one could use relative positioning with negative coordinates, but then if the map changes size you have to rewrite the coordinates in Javascript.
.ol-control.left-top {
position: relative;
top: -400px; /*map height*/
}
Is there a way to elegantly implement relative-positioned custom controls with OpenLayers 3, ideally with only CSS?
I guess I am trying to get a similar functionality as in the Google Maps API:
map.controls[google.maps.ControlPosition.LEFT_TOP].push(controlDiv);
Though it is not a good solution for my use case, since it is not supported by Android 4.3 and earlier, one could use CSS calc as suggested by #Jonatas:
html:
<div class="parent">
<div class="map"></div>
<div class="control"><button>CONTROL</button></div>
</div>
css:
.map {
width: 100%;
height: calc(100vh - 2em);
background-color: green;
}
.control {
position: relative;
left: .5em;
top: calc(-100vh + 2em + .5em);
}
This would probably have to use viewport units (also not supported by Android 4.3 and earlier), as calc can only calculate values based on the parent element.

I have a side menu organised in 2 levels,like
link1
link1.1
link1.2
link1.3
links 1.x are hidden (display:none, applied to the container div) and contained within a div (id = resume-2nd-level)
now, I created a css class:
#resume-2nd-level:target {
display:show
-webkit-transition: height 3s linear 1s;
transition: height 3s linear 1s;
}
link1's href property points to: #resume-2nd-level
My goal is to:
show link1.x when I click on link1 (eventually toggle them: show-hide-show- ..)
link1.x shall not appear immediately but with a css animation with the following specifications: expands in height, starts after 1 second, lasts for 3 seconds before being completely expanded
hide the #resume-2nd-level from browser url (as the link was triggered using Javascript)
However my code doesn't each neither of the two goals.
I tried to show the container containing the links using jQuery's show() onclick and it works (although no animation occurs).
Thanks in advance
The problem you are having is that transition does not work the way you think.
#innerMenu {
height:0%;
width:0%;
position:relative;
overflow:hidden;
-webkit-transition: height 1s linear 3s;
transition: height 3s linear 1s;
-webkit-transition: width 3s linear 1s;
transition: width 3s linear 1s;
}
#innerMenu:target{
height:100%;
width:100%;
}
<ul>
<li>
Menu1
<div id='innerMenu'>
<ul>
<li>Menu2</li>
<li>Menu3</li>
</ul>
</div>
</li>
</ul>
The above snippit shows the proper way to do this.
The transition property needs to see a change in order for it to fire. What you have right now is not changing anything. By trying to show the element you are not actually changing the size of it.
In the snippit you can see what is actually changing is the height and width and the transition can be applied to that change.
Also you need to animate the width because otherwise it will become unhidden instantly.
Bootstrap 3:
I'm trying to float a button center halfway outside the panel-footer. But the whole layout is responsive so I need to have it when the screen size is resized or smaller it is still correct.
I created a bootply with my attempt that is close but doesn't stay when the screen is resized.
Thanks,
Nate

Is this what you wanted to get? http://www.bootply.com/114327
.relative {
position: relative;
}
.absolute {
position: absolute;
}
.bottom-btn {
left: 50%;
bottom: -17px; /* half of the button height */
margin-left: -77px; /* half of the button width */
/* instead of bottom and margin-left, you can use translateX as well. */
}
play with css position property and use margin to get exact position. see the comments for the .bottom-btn class.
I am changing the height of a SlickGrid header and rotating the text in the header with the following CSS:
.slick-column-name {
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
-o-transform: rotate(-90deg);
transform: rotate(-90deg);
-webkit-transform-origin: 50% 50%;
-moz-transform-origin: 50% 50%;
-ms-transform-origin: 50% 50%;
-o-transform-origin: 50% 50%;
transform-origin: 50% 50%;
}
.slick-header-columns, .slick-header-column {
height: 200px !important;
}
For a better understanding, please take a look at this:
http://jsfiddle.net/2Nvc3/1/
The rotated text in the header is centered and cut off. How can I change the alignment, so that it starts on the bottom (the text should be left-aligned before the -90° rotation)?
The width of one of the columns is different on purpose.
Link to jsFiddle I played around for a while. Basically the problem was that the origin of rotation was the middle of your text/header. Since "Else else SOmeshing Else" is significantly longer than the other column names, it sticks out on both sides. Either way - changing the origin of location to the beginning of the text solves this issue. Then to center um...horizontally(after the rotation) the text we put a margin-left of 40% - at leat that looks good in Chrome, not exactly sure why it's not 50%. To center the text um...vertically(after the rotation) we just add a text-indent of -235px, which is dictated by the height chosen here to fit the text, which is 250px.
Dear folks.
Imagine a sprite image called icons.png assigned to css class .icons with various 10x10px graphs. Now you want another class which scales up the sprite graphics exactly twice 200% (making them 20x20 pixels on the screen)
How do I achieve this enlargement purely in CSS?
Much appreciated!
.icons, .iconsbig{ /* WORKS FINE */
background-image:url(http://site.org/icons.png);
background-repeat:no-repeat;
vertical-align: middle;
display: block;
height:10px;
}
.iconsbig{ /* make this one twice as big as the original sprite */
background-repeat:no-repeat;
height:20px;
background-size: 20px auto;
image-rendering:-moz-crisp-edges;
-ms-interpolation-mode:nearest-neighbor;
}
update:
problems with the above code:
It works in IE9, but not in FireFox, by most used browser doesnt know how to resize????
in IE9, the enlargement is smudgy and not neithrest neighbour pixel perfect at all??
It is supported in pretty much everything except for < IE9...
.iconsbig {
-moz-background-size: 20px;
background-size: 20px;
image-rendering:-moz-crisp-edges;
-ms-interpolation-mode:nearest-neighbor;
}
W3C spec.
Update
Looks like Firefox wants its vendor prefix (-moz) on the property.
You can use the css3 background-size property:
.iconsbig {
background-image:url(http://site.org/icons.png);
background-size: 20px 20px;
}
