What is the reasoning behind using this specific CSS and HTML structure for styling web pages?
<div class="page">
<div class="page-left-column">
<div class="page-left-column-container-box">
<div class="page-left-column-container-box-element-header-wrapper">
<h2>This is the header!</h2>
</div>
</div>
</div>
</div>
The above code snippet is often accompanied by CSS rules similar to this:
.page-left-column-container-box-element-header-wrapper {
color: red;
}
But wouldn't it be more efficient to structure the code like this:
<div class="page">
<div class="left column">
<div class="container-box">
<div class="element header-wrapper">
<h2>This is the header!</h2>
</div>
</div>
</div>
</div>
And accompany it with CSS rules like (not all might be necessary):
.page .left.column .container-box .element.header-wrapper {
color: red;
}
The latter approach seems more organized and easier to maintain. It allows for the use of specific CSS rules without repeating lengthy class names throughout the code. One downside could be the deep hierarchical dependency that the CSS selectors have, but this could be outweighed by the benefits of cleaner and more manageable code. Could the reason for using longer class names like
page-left-column-container-box-element-header-wrapper
be related to performance concerns? Are there other technical advantages that justify this naming convention, or is it simply a matter of complexity in styling rules?
