I need your help, I'm developing a responsive site, and contact page, the form may appear in two or one column.
This should happen in a mobile:
And this on a computer:
Any idea how to build this table? I've tried using just css, however the HTML of each td is this:
<tr>
<td colspan="2" class="single">Telefone</td>
</tr>
<tr>
<td colspan="2" class="single"><input class="input-left" type="text" id="telefone" name="telefone" maxlength="13" autocomplete="off" title="Digite um número de telefone para contato"></td>
</tr>
Any idea?
