here is the code i am using, it may not be the prettiest as i am in no way a coder but only knowledgeable about basic HTML… anyway it works for me:
<p>
<span style=”float: right”>
<input value=”Tilmeld” type=”submit” >
</span>
<span style=”display: block;
overflow: hidden;
padding-right: 10px”
<input value=”Tilmeld” type=”submit” > <input required=”required” placeholder=”Indtast email adresse” name=”EMAIL” type=”email”
</span>
</p>
