<input 
        type="text"
        placeholder="first and last name"
        required
        pattern="(.*)\s(.*)"
/>
    
<input 
        type="text"
        placeholder="username"
        pattern="/^[a-zA-Z0-9_]+$/"
        maxlength="15"
/>

<!-- leveraging on the power of regular expression to enforce validation rules to the pattern attribute 
and also adopting the maxlength which returns true when an element value length is longer than thethe value in the maxlength attribute
-->
