Form Elements in a Grid
In this example, we use W3.CSS' Responsive Grid System to make the inputs appear on the same line (on smaller screens, they will stack horizontally with 100% width). You will learn more about this later.
Example
<div class="w3-row-padding">
<div class="w3-third">
<input class="w3-input w3-border" type="text" placeholder="One">
</div>
<div class="w3-third">
<input
class="w3-input w3-border" type="text" placeholder="Two">
</div>
<div class="w3-third">
<input class="w3-input
w3-border" type="text" placeholder="Three">
