why do some styles inside jsx (in case of a width) stop working, for example, the red color span seems broken and does not change to the width value to 100px, the green ones without jsx work correctly

<style>
.title {
background: #e31937;
border-radius: 4px;
width: 100px;
height: 20px;
}
.test {
background: green;
}
</style>
</body>
</html>Why is this happening? And why, for example, background works correctly both inside jsx and without jsx
