CSS: Styling Input Fields

CSS

I’m working on a project where I’m using CSS to add a border radius and background image to an input field. Background images are supported by all browsers, but border radius is only supported by Firefox, Safari, and Google Chrome.

CSS: Placing One Image On Top Of Another

CSS

I have recently discovered two ways to use CSS to place one image on top of another. I am working on a photogallery management plugin (JQuery) and I wanted to add an delete image to the bottom right of each thumb image. The user will be able to click on the delete image to delete the thumbnail. The image below displays how I want the thumbnail to appear:

<img class="alignnone" title="Delete Example" src="http://grasshopperpebbles.com/images/posts/delete_example.png" alt="" width="118" height="85" />

The key to both approaches is to place the first image as a background image of a container.

.thumb {
     float:left;
     width: 100px;
     height: 100px;
     background:url(images/thumbs/pic1.jpg);
}

My first approach for styling the second image was to set the ‘background-position’ to ‘bottom right’.

.thumbDelete {
     width: 100px;
     height:100px;
     background:url(images/delete-24x24.png) no-repeat bottom right;
}

While this positioned the delete button where I wanted, because the dimensions are the same as the thumbnail image, the entire image became clickable (not just the delete image).

So my next approach was to float the delete image and set the margin-top to 50%:

.thumbDelete {
     float:right;
     width: 24px;
     height:24px;
     background:url(images/delete-24x24.png) no-repeat;
     margin-top:50%;
}

This placed the delete image on the bottom right (and only the delete image is clickable).

Creating the HTML is the same no matter which approach you take:

<div class="thumb">
<div class="thumbDelete"></div>
</div>

Easy enough.
