Consider this basic example of a form that I frequently use:
<form class="login">
<input class="login_username" type="text" value="username"/>
<input class="login_password" type="text" value="password"/>
<input type="submit" value="Login"/>
</form>
However, after reading some books and observing my friends, I've noticed that they often structure their forms like this:
<form class="login">
<div class="login_username">
<input class="login_input" type="text" value="username"/>
</div>
<div class="login_password">
<input class="login_password" type="text" value="password"/>
</div>
<input type="submit" value="Login"/>
</form>
The difference lies in the fact that they tend to wrap all components inside a div tag and assign it a class name, even if there's only one component within the div. I'm unsure of the advantages or reasons behind this approach.
Thank you :)
