This works in IE7+ and all modern browsers.
.formLine {
overflow: hidden;
background: #ccc;
}
.formLine input {
width: 100%;
}
.formLine label {
float: left;
}
.formLine span {
display: block;
overflow: hidden;
padding: 0 5px;
}
.formLine button {
float: right;
}
.formLine input, .formLine button {
box-sizing: border-box;
}
<div class="formLine">
<button>click me</button>
<label>some text.. </label>
<span><input type="text" /></span>
</div>
The button
must go first in the HTML. Slightly distasteful, but c’est la vie.
The key step is using overflow: hidden;
: why this is necessary is explained at:
- http://colinaarts.com/articles/the-magic-of-overflow-hidden/#making-room-for-floats
- How does the CSS Block Formatting Context work?
The extra span around input
is necessary because display:block;
has no effect for input
: What is it in the CSS/DOM that prevents an input box with display: block from expanding to the size of its container
