I got an Image which is 400px x 685px. In the website, i set it will only show 200px x 685px. I want to know how to show the whole image when the mouse hover the image and show another half of the image 200px x 685px to 400px x 685px? Thank you
So I think a part of your css may looks like:
.your-class {
background: url("[the path of your image]");
background-size: 200px 685px;
}
then for when the mouse hover the image:
.your-class:hover {
background-size: 400px 685px;
}
Note that if you're using the <img> tag itself in your .html file, then you should write width and height instead of background-size. Anyway The code above is somehow what developers do in css in this case. But obviously it really depends on how you've structured your HTML with div tags and also the classes you've given to these tags.
you achieve by set
.selector:hover
{
background-size: 100% 100%;
}
I think an acceptable solution would be to create a div in your html. In your style sheet (aka - css file) you should define it with width:200px, height:685px; the next thing you want to do is to set all divs tags (or any id you give this fella) a background-image:url("whatever.png");
Now, you should also use the background-position:right (or left, your choice).
whta will happen so far? Your div will show half an image.
Now you should use div:hover as a new set of rules in your css, and there also use the background-position:left/right (the one you didnt use).
Tell me if it works.

Here is my project (1000px x 1230px). I want this element taken from my project (this header picture originally has 1500px x 354px) to:
1. be inserted with background-image property
2. that background-image to be direct child of body tag and
3. so that height and width would scale proportionally along with scaling the browser window.
If it was possible to carry out the above operation the paramerers would be width:100% hight:19.19% but when I enter hight:19.19% the image does not show at all, QUESTION: WHY IS THAT SO? I inserted background-image into section tag and this is how it seems to somehow work (but I do not know why it works):
section.super {
position:relative;
padding-top:11.8%;
padding-bottom:11.8%;
background: url(header.jpg);
background-size:100% 100%;
margin: 3% auto 0;
}
If I insert a div or article inside the given section tag above and specify width and height with % for background-image inside this div or article, the height WOULD WORK. But as a direct child of body tag the height does not work, why is that?
I know that there is an alternative IMG TAG but it will not work in rensponsive layouts where in different page sizes I will want substitute different .jpg (for instance) files (with higher and lower size) in which case I would need to paste different images to the same element in mobile styles, in tablet styles and deskop styles.
Although I am not sure i completely understand your problem, have you tried to use:
background-size:cover;
instead of:
background-size:100% 100%;
?
on your file css you should put:
body {
background-image: url("http://s12.postimg.org/ymlx2m65n/header.jpg");
}
I'm having a big issue with something so "small" I can't figure it out and I'm reaching out to everyone here. The issue I'm having is this:
I have photos which are roughly 512px or 800px wide I want to fit, CENTERED, in a circle display area and keep my hover effects. I also need to size them the photos so the centered part shows a decent amount of the photo.
The current code I'm working with will make them perfect circles IF the photos are perfect squares. The problem is when the photo is a rectangle, it turns into an oval.
I had created a div like below using overflow:hidden and the css but it conflicted with the current CSS. Any help would be appreciated immensely!
.thumby {
width:200px;
margin: 0 auto;
overflow:hidden;
position: relative;
height: 200px;
border-radius: 100% 100% 100% 100%;
}
img.absolutely {
left: 50%;
margin-left: -256px;
top: 50%;
margin-top: -200px;
position:absolute;
width:512px;
}
Here's the link to my dev pages.

have you thought about setting the image as the background of the div? This way you keep all the effects you already use and there are ways to manipulate the background position without affecting the outside div. Other possible solution to have perfect round divs, is to use the ::after pseudo-class, like in this gallery tutorial:
http://webdesignerwall.com/tutorials/decorative-css-gallery-part-2
Sorry if I misunderstood you, hope it helps.
PS.: Beautiful test page by the way.
Well first, you'd only need to set the border radius to 50% to make something a circle, and if each corner is the same value, then you can just enter it once like so:
border-radius:50%;
As far as these images being rectangles goes, you could set your images as the background of a span, give it a height and a width that forms as square and use display block. This would keep the photos proportional, but allow you to make them square.
This however, could create a bit of a markup mess if you have a lot of images to display. Another solution, which means more work, but I would personaly do it, is to just crop your images into squares for their thumbnail with photoshop or some other image editing tool.
Above all of that, I don't see a width or height actually declared on the pages you linked. Are you sure you've placed them on the correct class? I see the border radius declared, but I'm only seeing a max-width: 100%; not width: 200px or height:200px
I re-thought the problem with the suggestion of using the images as backgrounds of an element as madaaah did above.
What I ended up doing was wrapping a DIV around my A tag like this:
then, I set the background of the A like this: style="background:url(PHOTO URL HERE) no-repeat;background-position:center;">
lastly, I made a square image (800 x 800) to go inside the A tag so it would keep the round shape and made it completely transparent so the background image is visible, while growing and shrinking in a "responsive" manner.
This is my issue.
I have a menu using an image sprite, the image has transparencies, but when I add a :hover, it works, but I am still able to see the original image at the end.
Is there a way to make the hover show the image that I want and REPLACE the original one?
Thanks,
Marco
You can replace an image by using it as a background-image instead of using the <img> tag.
But most of the times, this is slow and another way is maybe good practice:
Create an image that has the :hover image next to it [img|hoverImg]
Do a styling with background-position to change the background.
Like this:
.menuItem
{
background-image: url('hello.jpg');
width:100px;
height:30px;
}
.menuItem:hover
{
background-position: 100px; /* Or whatever measure your image is */
}
The problem with this, is that the image size is fixed. You really have to specify it, instead of just doing this with an image.
I like this as the best way. If you want to set the src in your <img>, this can be done with Javascript, but is much heavier most of the time, because you have to load an extra image from the server.
How can I do to have an image as the background for all links? I want to have a nice box representing buttons, but I cannot figure this out.
I have tried:
a {
font-size: 40px;
background: url('images/shooting-stars/shooting-star-link.png') no-repeat left top;
}
But this is not working, image is not displaying.
"I want to have a nice box representing buttons, but I cannot figure this out." - I don't understand this part.
Anyway, your css looks fine from here, are you sure the image exists? This is a working example with the exact same code, just an image that I'm sure exists:
http://jsfiddle.net/3k9nm/
If you want to always show the image, even if the text is shorter, you should set a minimum width for the links. This does mean they'll have to be inline-blocks, you can't set width on a regular link (which is an inline element).
a {
display: inline-block;
min-width: 25px;
}
(25px was randomly chosen, fill in the width of your background image..)
Two things to try, is there any text in the actual <a> links? And if you use Firebug, you can check you've definitely got the right file path to the image...
HTML
<div id="example-link">
Link to journal article
</div>
CSS
#example-link a {
background: url('images/shooting-stars/shooting-star-link.png');
}
I am wondering if anyone knows how to achieve the following - take a look at http://www.dspts.si
The first 1/3rd of the screen has an empty background and from there onwards there should be a pattern repeating. I did it right now, by creating a very long pattern png and set it to offset 300 and repeat-x. However, I'm not happy with this solution because it will break if the pages ever get longer than the background image png is.
Thanks for any suggestions!
Put the repeating pattern as background to html element, then a white 1px * 300px image as an background image to body element, and you're all set.
html, body {
height: 100%;
}
html {
background: url(dotted.png);
}
body {
background: url(white_1x300.png) 0 0 repeat-x;
}
You don't have to use html and body tags for this, but it's the easiest way and doesn't require any new markup.
You can specify multiple backgrounds. See Can I have multiple background images using CSS?. The techniques mentioned there are:
Put the whole page into another <div> container or misuse the <html> tag for it.
This means you specify a background for <body> and one for <html>.
Use CSS3 which support multiple background images. That's not yet supported by all common browsers.
Yes, specify your background image as normal but set the background-position like this:
background-position:0 300px;
This will make the background image start at 0px from the left, and 300px from the top.
Let's not forget that you can use FireBug with FireFox to easily diagnose techniques on websites.
