To ensure that the height and width of a parent div that contains a child textarea are exactly equal, you can utilize the following CSS code snippet: https://jsfiddle.net/BwVQZ/7/
<div>
<textarea></textarea>
</div>
div{
height: 200px;
width: 300px;
background: red;
}
textarea{
height: 100%;
width: 100%;
-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box; /* Firefox, other Gecko */
box-sizing: border-box; /* Opera/IE 8+ */
}
However, the downside of the above method is that it involves specifying fixed height and width values for the div, which may not be feasible in certain scenarios.
When the height and width are not hardcoded, the div may end up slightly larger than the textarea: https://jsfiddle.net/731ce2u4/
<div>
<textarea></textarea>
</div>
div{
background: red;
}
textarea{
height: 100%;
width: 100%;
-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box; /* Firefox, other Gecko */
box-sizing: border-box; /* Opera/IE 8+ */
}
Is there a way to achieve equal height and width for both the div and textarea without explicitly setting any specific dimensions? Feel free to share your insights!
