Overflow Issue
Example
的中文翻译为：示例
Let us see the problem first before moving towards the solution. We have an image here, floated to the right. It overflows outside its container since it is way taller than the element belonging to it −
<!DOCTYPE html>
<html>
<head>
<style>
div {
border: 2px solid blue;
padding: 5px;
}
.myimg {
float: right;
}
</style>
</head>
<body>
<h2>Demo heading</h2>
<p>We haven't used clearfix below:</p>
<div>
<img class="myimg" src="https://www.tutorialspoint.com/machine_learning_with_python/images/machine-learning-with-python-mini-logo.jpg" alt="Machine Learning" width="150" height="150">
Etiam accumsan metus sapien, rutrum sagittis nunc posuere eu. Ut facilisis tortor eget justo
scelerisque, quis porta nisl sagittis.
</div>
</body>
</html>
The output displays the overflow issue −
