<span data-bar> ... </span>

span[data-bar]{ ... }
Do you agree with this coding practice? Are there any potential pitfalls?
I believe implementing the data- attribute is beneficial when dealing with a large number of "bar" elements, as it helps reduce the size of the HTML markup (-3 characters for each element).
div[data-foo] is not compatible with outdated versions of IE (such as IE6, refer to http://www.quirksmode.org/css/selectors/)div[data-foo] lacks semantic clarityclass="foo" and data-foo occupy similar space when DEFLATE-d. Make sure your server is configured for deflation.class=foo and data-foo is minimal even when uncompressed, and both are valid HTML.Your choices play a key role in styling elements, as they may have unique attributes that require specific styling. In such cases, defining styles and potentially repeating them becomes necessary. Using a class allows for greater flexibility compared to attribute selectors which restrict properties based on specific elements with those attributes. Classes can be applied across different element-attribute combinations, providing more versatility.
.class { /* Utilize this versatile class wherever needed */
font-family: Arial;
font-size: 13px;
}
On the other hand, using an attribute selector can limit your styling options to a particular element-attribute combination.
div[data-menu] { /* This limits styling to div elements with a data-menu attribute */
font-family: Arial;
font-size: 13px;
}
It's crucial to consider specificity to avoid confusion and ensure consistent styling decisions.
