Question

Is it valid to replace elements with <element /> to <element></element>. In this case i want to have,

<input {attributes}></input>

just so i can append validation data within… Also could this be possible from a <br /> or <hr /> etc?

Answer 1

The <input> tag does not have a </input> and there is no need for one. Same for <br> and <hr>. You can put validation data as attributes on the input tag (or any tag) with custom attributes like this:

<input type="text" data-validate="num">

If what you mean by validation is separate HTML that you want to display near the input tag, then put it in it’s own tags before or after the <input> tag:

<input type="text"><span class="validHint">This field accepts only numbers</span>
