I want to position several images inside a div block. The position of the images inside it should be relative to that div.
Should I put each image inside a block of its own size and position those blocks relatively to the bigger block? (So in any browser the block will look the same!)
You can do it like this. Here's a simple mock up.
the Html
<div>
<img src="/1st.jpg">
<img src="/2nd.jpg">
<img src="/3rd.jpg">
</div>
The css
div { display: block; }
img { display: inline-block; position: relative; float: left; }

I have a png with blue lines, a transparent background and nothing else. Is there a way in css to make the lines white?
CSS is used to modify the appearance of HTML. It cannot really affect an image directly. You could use two images of the same size, and use JavaScript to switch between them.
Here's one possible way to do this:
HTML
<body>
...
<div>
<image id="blue-img" class="currentFrame" src="/img/blue.png" />
<image id="white-img" class="hiddenFrame" src="/img/white.png" />
</div>
...
</body>
CSS
.currentFrame {
display: block;
}
.hiddenFrame {
display: none;
}
At this point, you could use the following JavaScript to hide one image and show the other. Because the images are the same size, and appear together in the HTML DOM, it will look like the images occupy the same space.
function changeFrame() {
removeClass("blue-img", "currentFrame");
addClass("blue-img, "hiddenFrame");
removeClass("white-img", "hiddenFrame");
addClass("white-img", "currentFrame");
}
// Add the given class to the DOM element with the given id
function addClass(id, class) {
...
}
// Remove the given class from the DOM element with the given id
function removeClass(id, class) {
...
}
The implementation of addClass and removeClass() functions are left as an exercise for the reader, but it can be much easier if you use jQuery or some other DOM API library.
You could also use the HTML5 <canvas> element, if you're not concerned about backwards compatibility, or if you need a transition animation. That would also involve some JavaScript coding.
You have at least 2 ways to achieve this effect
Option 1: Use the image as a mask
Here only the transparent part of the image is used, as a mask. If you apply it on a white element, the parts not masked will be white
.base {
width: 300px;
height: 200px;
background-color: yellow;
}
.test {
width: 300px;
height: 200px;
background-color: white;
-webkit-mask-image: url(http://upload.wikimedia.org/wikipedia/en/2/2d/SRU-Logo-Transparent.png);
-webkit-mask-size: contain;
}
<div class="base">
<div class="test"></div>
</div>
Option 2: use a filter to change the color. For instance, use brightness(100)
.base {
width: 300px;
height: 200px;
background-color: yellow;
}
.test {
width: 300px;
height: 200px;
background-image: url(http://upload.wikimedia.org/wikipedia/en/2/2d/SRU-Logo-Transparent.png);
background-size: contain;
-webkit-filter: brightness(100);
}
<div class="base">
<div class="test"></div>
</div>
However, both options have a limited support
Why don't you use the Canvas in HTML5 to create the image on user interface :-
it will give you more clarity as the images are created using px.
it will give you liberty to change in what every color, size you want as they are created using javascript .
I want to add a image hover effect on only the div images not the whole html code. How do I do this?
Take a look at how to "nest" CSS selectors.
Here's an example. Is this what you need?
<div>
Image in a div
<img src="http://baconmockup.com/300/200" />
</div>
div img:hover {
border: 1px solid red;
}

I've used Caroufredsel in my website as an image slider.
I want to make it like the first example in
http://caroufredsel.dev7studios.com/
but whenever I put images withing <a></a> tags, slider disappears. As I remove <a></a> tags, everything runs fine.
How can I make images clickable to direct to another page in Caroufredsel?
CarouFredSel operates on block-level elements with set height/width. <a></a> tags are inline-elements. I recommend surrounding the <a></a> tags with <div></div> tags and styling the <div></div> tags to have a set height/width, display:block and float:left. This has worked for me:
#carouselWrapper div {
display: block;
float: left;
width: 500px;
height: 200px;
}
Then call the jCarouFredSel initiator on #carouselWrapper.
No need to add the extra div element - simply set your <a> elements to display: block.
#carousel a {
display: block;
float: left;
}
I have a html document structured with a header, content, and footer divs. I am trying to center an image (a logo) inside my header div to display at the top of my webpage in the middle. I can absolute position it into the middle, but when I change the browser size, the img doesn't move along with it. I want it to be place automatically in the center of the window. I am stumped..?
I have tried , margin-right:auto; margin-left:auto. I have also tried the trick where you make margin-left negative half the width and top 50%, but nothing has worked so far.
html:
<body>
<div id="container">
<div id="header">
<img id="logo-img" src="http://f.cl.ly/items/3c0h1b0F3t1D1S1T2J0F/smallersticker.png">
</div>
/*...(body div)
...(footer div)*/
</div> /*container*/
css:
#header {
background-color:transparent;
height:260px;
width:100%
}
#logo-img{
display: block;
margin-left: auto;
margin-right: auto;
}
Also, Do I even need a container? Not sure if I need javascript for this, or if it can be accomplished with just html/css? Hope someone can help, thanks!
What is happening is that you are already correctly centering your image.
Your problem is that the image is huge. If you notice closely, the image is not centered if your browser window becomes smaller in width than the image.
Remove the white area from the image and it will center correctly.
Edit: in IE, you need to add the rule text-align:center to #header
Another way:
If you don't want to change your image, you can use this hack:
<style>
#header {
overflow-y: hidden;
background-color: transparent;
height: 260px;
width: 100%;
margin-left: 50%;
}
#logo-img{
display: block;
position: relative;
right: 50%;
}
</style>
<body>
<div id="container">
<div id="header">
<img id="logo-img" src="http://f.cl.ly/items/3c0h1b0F3t1D1S1T2J0F/smallersticker.png">
</div>
/*...(body div)
...(footer div)*/
</div> /*container*/
I learned this hack a while ago here
Just use the logo at a size it's supposed to be (like this here), then all you need to do is add the align="center" attribute to your logo's div.
I have 3 divs in a container div. The first is floated left, the second is floated right and the last sits in the center. This creates 3 approximately even divs across a container div.
In each of these divs I am placing an image of varying heights. Then there is a separate div to sit below the container div which will be the full width (call it description div).
I want the container div to stretch to height of largest image div so that the description div sits nicely underneath the images. Currently this works when the left floated and middle divs contain the largest image but not for the right floated div. I cannot see why or what i'm missing any help would be much appreciated.
NOTE: I'm trying to do this without using any absolute values, just percentages. So I don't want to declare an absolute height to the container div! Also clear's will not work as this is simplified and there are actually a lot of other div containers around all of this etc, unless you can clear just the floats in the above nested div.
Here's the code:
<html>
<head>
<style>
#b_pics {
border: 2px solid grey;
width: 100%;
}
#b_pic1 {
border: 0px solid grey;
float:left;
width:33%;
}
#b_pic2 {
border: 0px solid grey;
margin: 0px auto;
width: 33%
}
#b_pic3 {
border: 0px solid grey;
float:right;
width:33%;
}
#b_website {
border: 1px solid grey;
width:100%;
}
</style>
</head>
<body>
<div id='b_pics'>
<div id='b_pic1'>
Image 1 here
</div>
<div id='b_pic3'>
Image 3 here
</div>
<div id='b_pic2'>
Image 2 here
</div>
</div>
<div id='b_website'>

</div>
</body>
Thanks in advance for any help, trying to keep any hair thats left in my head!
A containing element won't stretch to accommodate floating divs. In your example, the the containing div has no actual content and will thus be 0 pixels high. Try changing the border or background colour to illustrate this.
You can force an element to be below any floating divs by giving it the style:
clear: both;
You can also clear just left or right floating divs.
You can add an empty div after your three picture divs that has that style, to make the b_pics container stretch to accommodate the floating elements, or you could just make the b_website div clear both.
I totally agree with SpoonMeiser answer. I had the same problem (only with IE do) and adding a clear: both (div in my case) is the only solution that seems to work.
SpoonMeiser's explanation is correct. Here is some code that should work for you. Essentially, I've added an empty div with "clear:both" at the end of your container div. This forces the container to take up the space of the floating divs it contains.
This is better than making the #b_website div "clear:both" (SpoonMeiser's alternative suggestion) because that would make the #b_website div display in the correct place but would not force the #b_pics border to surround the floating divs.
<div id='b_pics'>
<div id='b_pic1'>
Image 1 here</div>
<div id='b_pic3'>
Image 3 here
</div>
<div id='b_pic2'>
Image 2 here
</div>
<div style="clear:both;"></div>
</div>
<div id='b_website'>

I hope that helps?
Give this a shot. Nothing's hard-coded, and it should do what you want.
