I'm using Twitter Bootstrap and I want to implement a overlay panel when mouse hover the img tag, like in Stackoverflow when details is showed when the focus is in the image of the user.
This image illustrate:
Someone how I do this?
Thanks.
Whatever you want as the "hovering" object, just give position: absolute, then have a :hover selector, for example:
HTML
<div>
<div class="Profile">
Basic Profile
<div class="Overlay">
Put overlay stuff here.
</div>
</div>
</div>
CSS
.Profile{
position: relative;
}
.Overlay{
position: absolute;
top: 100%;
left: 0px;
opacity: 0;
height: 0;
}
.Profile:hover .Overlay{
height: auto;
opacity: 1;
}
So now, when a user hovers over the .Profile div, the .Overlay contained within it will appear, then add any additional styling for transitions and making it pretty.

I am trying to do something basic (beginner in programming).
I try to take a large image and a smaller container, and move the image up or down inside while the user scrolls.
So you can .
Move the yellow up or down while the user can see the red in the same position (kept in doc flow).
If i create an image using this :
<div class="cvrContainer top left">
<div class="cvrPhoto" id="photo0" style="background-image: url(https://picsum.photos/900/850);"></div>
</div>
Should i set cvrPhoto to be larger then cvrContainer say 200% ?
How do i move it up/down with JS while keeping overflow hidden.
I do not ask how to calculate, only how to set it and move the only yellow inside
If you want to create simple parallax effect, you can achieve this effect by position fixed, add position: fixed on .cvrPhoto div.
.cvrContainer {
padding: 30px;
width: 100%;
height: 2000px;
overflow: auto;
background: url(https://picsum.photos/900/850);
}
.cvrPhoto {
height: 300px;
width: 200px;
position: fixed;
top: 57px;
background: yellow;
}
<div class="cvrContainer style=" background-image: url(https://picsum.photos/900/850); "">
<div class="cvrPhoto"></div>
</div>
I solved it by using css for the inner image (not background image but img tag) :
.prlxPhoto
{
position: absolute;
left: 50%;
top: 50%;
-webkit-transform: translateY(-50%) translateX(-50%);
}
and move it left/right for example with :
var e = document.getElementById("1");
e.style.marginLeft = equotion+'px';
I'm trying to replicate the menu design used by:
https://www.pandaexpress.com/menu/appetizers
I think I am at the point where I need to use javascript/jquery, but I'm very new and unsure of my next step. When the user hovers over an image the image seems to slide into focus and display information below. I have tried to isolate this into separate actions, modeled by the following jfiddles:
https://jsfiddle.net/Lrqu8L0q/3/ (enlarges and focuses image on hover)
https://jsfiddle.net/4ud7wnop/1/ (slides down to reveal text on hover)
I tried combining them but when I add the
<p>This text is displayed on a downward slide after hover</p>
to the first jfiddle the paragraph isn't hidden.
Now I'm having trouble trying to think of a way to combine the both. I think I need to use javascript/jquery to create a function that applies the slide down to reveal text after the image enlarge has been completed. I'm very new to web design as a whole and am especially shaky with javascript and jquery.
I was wondering if I could write a function that checks if the image has expanded on enlarge yet, and after it's reached a desired height/width run the text slide function. Really not sure how to do this.. could someone point me in the correct direction?
I merged them together here: https://jsfiddle.net/danbovey/53ya31gm/
The main problem was, you need the image to be larger to cover over any detail text you may have.
I have commented on most changes I added in the fiddle. But here's the key parts:
I renamed the bg element to tile, it seemed more appropriate. Instead of working with height for the .slide-down class, I created a transform on the details div when the tile is hovered.
.tile:hover .details {
transform: translateY(150%);
}
You can learn about CSS transforms here: http://css3.bradshawenterprises.com/transforms/
The percentage of the transform can be calculated as the height of img / height of details - 300px / 200px = 150%
To create the growing effect, a pseudo :before element adds a white area the same size of the image before the tile, and when hovered, grows to 25px around each edge. And an identical element is added to the details div.
.tile:before {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: #FFF;
transition: all 0.4s ease;
content: '';
}
.tile:hover:before {
top: -25px;
left: -25px;
width: calc(100% + 50px);
height: calc(100% + 50px);
}
Is this what you want here?
https://jsfiddle.net/Lrqu8L0q/9/
.thumbnail{
width: 100px;
height: 100px;
display:block;
z-index:999;
cursor: pointer;
-webkit-transition-property: all;
-webkit-transition-duration: 0.3s;
-webkit-transition-timing-function: ease;
margin: 0 auto;
position: relative;
top: 50%;
transform: translateY(-50%);
border-radius: 2px;
}
.bg:hover {
transform: scale(1.25)
}
.bg{
width: 150px;
height: 110px;
background-color: teal;
border-radius: 2px;
}
.slide-down {
border-radius: 3px;
height: 60px;
width: 150px;
position: relative;
transition: height 0.3s;
-webkit-transition: height 0.3s;
text-align: center;
overflow: hidden;
background-color: teal;
}
.bg:hover .slide-down {
height: 140px;
}
.container{
position: relative;
left: 150px;
top: 50px;
}
<div class="container">
<div class="bg">
<img src="https://static.pexels.com/photos/70497/pexels-photo-70497.jpeg" class="thumbnail"/>
<div class="slide-down">
<h2>Title</h2>
<p>This text is displayed after a downward slide on hover</p>
</div>
</div>
</div>
Basically what you need to do is put both your requirement into 1 combined object (in this I mean put both the Image & Text inside 1 container) like in the above example
<div class="bg">
<img src="https://static.pexels.com/photos/70497/pexels-photo-70497.jpeg" class="thumbnail"/>
<div class="slide-down">
<h2>Title</h2>
<p>This text is displayed after a downward slide on hover</p>
</div>
</div>
Both of them are put inside 1 container with class .bg, then what you want is to hover the container (not the thumbnail or description itself) and trigger both the scaling & slide-down the menu detail, you can do this by adding the CSS
.bg:hover { ... }
For the scaling, you need to put it together with the container so all the elements inside will be scaled to, then for the description inside it, you need to use
.bg:hover slide-down { ... }
This is where you set the animation that will expand the description of the menu (for explanation, this CSS will trigger on .bg hover, and applied to the element .slide-down inside of it)
I have asked questions like this and have not really got an answer that really helped me! I know it is probably very easy and i just can't figure it out!
I have been studying jQuery for a few days now and have the basics down but cant create the right function to make this effect happen! Please visit the website below!
There are a few things i would like to know about! The first thing is when you first go to the site everything slides into place (sidebar, footer, etc.) The main concern is the sidebar how when you hover over one of the icons a kind of tool-tip eases appears and eases to the right side.
The next part i would like to know is when you click one of the icons a whole another window pops out. I kind of have an idea of how these both happen but i cant put all the pieces together. Please help me out! I know it cannot be that difficult. Even if you know of any jQuery plugins that can help achieve these results, would be even better!

HTML
<div id="sidemenu">
<div id="regionsContainer">
<div id="regionsUnitedStates"></div>
</div>
</div>
CSS
#sidemenu {
width: 60px;
height: 100%;
min-width: 60px;
height: 100vh;
max-width: 60px;
background-color: #383D3F;
background-size: 100% 100%;
background-attachment: fixed;
margin-top: -8px;
margin-bottom: -8px;
margin-left: -8px;
position: absolute;
}
#regionsContainer {
width: 60px;
height: 481px;
min-height: 481px;
min-width: 60px;
max-width: 60px;
max-height: 481px;
background-color: #383D3F;
position: relative;
top: 25%;
bottom: 25%;
}
#regionsUnitedStates {
width: 60px;
height: 60px;
background-image:url(../_images/_header/regionsUnitedStates.png);
}
#regionsUnitedStates:hover {
background-position:bottom;
}
you can do that using position: absolute like mentioned by fizzix before, and for each of your question with this html example
<div id="sidemenu">
<div id="submenu" class="not-open">
Sub
<div id="submenu-inner">
inner
</div>
</div>
<div id="submenu-item1">
item
</div>
</div>
1 The first thing is when you first go to the site everything slides into place (sidebar, footer, etc.)
This can be achieved with jQuery on document ready, and using setTimeout if you want to further delay it, then add a class to the element, like this
CSS :
#sidemenu {
background: #000;
width: 50px;
height: 100%;
position: absolute;
left: -50px;
transition: left ease-in-out 0.5s;
}
#sidemenu.show {
left: 0;
}
jQuery :
$(function() {
setTimeout(function() { $("#sidemenu").addClass("show") }, 500);
});
2 The main concern is the sidebar how when you hover over one of the icons a kind of tool-tip eases appears and eases to the right side.
This can be achieved with only CSS on hover, what you need is put the floating element inside the element you want to hover, in this example submenu-inner inside submenu, then add some CSS
#submenu {
background: #fff;
height: 50px;
margin: 150px 0 0 0;
text-align: center;
position: relative;
}
#submenu.not-open:hover #submenu-inner {
left: 50px;
opacity: 1;
}
#submenu-inner {
opacity: 0;
position: absolute;
transition: all ease-in-out 0.5s;
top: 0;
left: 250px;
height: 50px;
background: #f00;
}
firstly, the inner element is transparent and positioned more to the right using left, then on hover, set the position right beside the container, by setting the left CSS again to the width of the container
3 The next part i would like to know is when you click one of the icons a whole another window pops out
it's the same with number 1, except this one triggered by onClick event
here's the working example on JSFIDDLE
I dont think any plugin is required.
You can use translate to keep the menu hidden.transform:translate(90%)
Please refer this example:JSFIDDLE
The entire site is using absolute positions. This means that they are positioned on the page with pixel co-ordinates. They then using jQuery animate to move the top and left positions.
I have made a brief example of how to do this HERE. You can edit this to your liking.
If you are interested in seeing what the site was built with, you can see a whole list HERE
So I have two images, one is a half of a ribbon and the second one is a full ribbon with facebook etc links on it. I need to have the first one in the middle of a page, so when you click it it would expand out. I figured i need to use hidden overlay or something but I am totally new at javascript.
Can someone provide an example or help me with this?
I tried to understand what you want and tell me if this is what you meant.
You can wrap the two images in two sepatare divs and then wrap them in a div with position relative.
Then you give to the two divs position absolute.
On the click of the first div you change the second div left position (or the top if you want a vertical effect).
Here is the html with divs only:
<div style="position: relative">
<div id="frontDiv">
aaaaaaaaaaaa
</div>
<div id="backDiv">
bbbbbbbbbbb
</div>
</div>
Here the CSS:
#frontDiv{
height: 20px; width: 45px;
background: red; position: absolute;
z-index: 1; left: 0px; top: 0px;
}
#backDiv{
height: 20px; width: 30px;
background: blue; position: absolute;
z-index: 0; left: 0px; top: 0px;
}
And here the javascript (in jQuery):
$("#frontDiv").click(function(){
$("#backDiv").animate({"left":"45px"}, 300); //{"top":"20px"} for vertical effect
});
At the end you can position the wrapper div wherever you want.
Full example at this fiddle: http://jsfiddle.net/w7RVe/
Not the best with jquery, can someone suggest a general approach for what i am trying to achieve please? I have a grid of photos, and when they are clicked on, an opaque overlay will be animated on top of the entire picture, the overlay will contain some dynamically set text. I have the images, and the onclick handler working, just trying to figure out the best way to apply the overlay. thanks
Not very pretty semantically, but should get the job done :
Let's say your imgs are 200x200.
<div class='imgcontain'>
<img src='yourimg' alt='' width='200' height='200'>
<p>Your text>/p>
</div>
<div class='imgcontain'>
<img src='yourimg' alt='' width='200' height='200'>
<p>Your text>/p>
</div>
<div class='imgcontain'>
<img src='yourimg' alt='' width='200' height='200'>
<p>Your text>/p>
</div>
// etc...
Then, the CSS :
.imgcontain
{
position: relative;
width: 200px;
height: 200px;
overflow: hidden; // not sure you want to makes the overlay just show or slide from top. This is useful only if it should slide.
}
.imgcontain img
{
position: absolute;
width: 200px;
height: 200px;
top: 0px;
left: 0px;
z-index: 2;
}
.imgcontain p
{
position: absolute;
display: block;
width: 200px;
height: 200px;
top: 0px; // if slide from top, -200px
left: 0px;
background: rgba(0,0,0,0.5) // or a background image like a transparent png with repeat
z-index: 1;
}
.imgcontain:hover p
{
z-index: 3; // if slide from top, top: 0px
}
This is a pure CSS solution, without animation, works for users with Javascript of.
If you want then to animate it using Jquery :
$(.imgcontain p).hide().css('z-index','3'); // on ready, hide the overlay. Maybe throw the .css() in callback.
then, on click/mouseover
$(.imgcontain).click(function()
{
$(.imgcontain p).show();
});
