In a scenario where a button and an input field are enclosed within a div with a bootstrap class named input-group, they expand to occupy the entire width of the enclosing element. However, if the button is hidden, the input field unexpectedly contracts to a default length instead of maintaining the full width. The situation is illustrated as follows:
To examine the code related to this issue, please refer to the following link: http://jsfiddle.net/1gu6qnhk/1/.
In essence, the problem can be demonstrated by the following code snippet:
<head>
<style>
.group {
display: table;
}
.input {
width: 100%;
}
.item {
display: table-cell;
width: 1%;
}
</style>
</head>
<body>
<div class="group">
<input class="input" />
<span class="item"></span>
</div>
<div class="group">
<input class="input" />
<span class="item">text</span>
</div>
</body>
The question arises as to why the first div expands to the full width while the second div only occupies a fraction of the available width, given that the sole distinction is the presence of text within the span element in the second div.
