I'm trying to design a basic layout for an html email template. Most examples I've seen use a main wrapper table; I wrote this instead:
<body>
<center>
<table width="600" style="width:100%;max-width:600px;margin: 0 auto" align="center">
<tr>
<td>
<table width="600" style="width:100%;max-width:600px;margin: 0 auto" align="center">
<tr>
<td>
<img src="banner.jpg" alt="" style="width:100%;max-width:600px;height:auto" width="600" />
</td>
</tr>
</table>
</td>
</tr>
</table>
<table width="600" style="width:100%;max-width:600px;margin: 0 auto" align="center">
<tr>
<td width="50%">
<table align="center">
<tr>
<td>
<p>content</p>
</td>
</tr>
</table>
</td>
<td width="50%">
<table align="center">
<tr>
<td style="text-align:center">
<p>content</p>
</td>
</tr>
</table>
</td>
</tr>
</table>
</center>
</body>
As you can see, there is a first table, for the image banner, and then, instead a second row, there is another separate table. Is it correct as approach? I intended it like separated a website using the section tag.
I have taken your code and made slight changes and added in what @gwally has suggested. The below code will work on all devices that support media queries (including Gmail App). Give the code a spin (run code, go full screen then resize browser) to see how it works.
You can change the media query to 480px if you want it to target smaller devices.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Lime in the coconut</title>
<style type="text/css">
.container{width:600px;}
@media only screen and (max-width:601px) {
.container{width:100% !important;}
.banner img{width:100% !important; height:auto !important;}
}
</style>
</head>
<body>
<center>
<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" class="container" style="max-width:600px;margin: 0 auto">
<tr>
<td>
<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" style="max-width:600px;margin: 0 auto">
<tr>
<td class="banner">
<img src="https://i.sstatic.net/AKVzJ.png" alt="" style="max-width:600px;height:auto" width="600" />
</td>
</tr>
</table>
</td>
</tr>
</table>
<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" class="container" style="max-width:600px;margin: 0 auto">
<tr>
<td width="50%">
<table border="0" align="center" cellpadding="5" cellspacing="0">
<tr>
<td>
<p>content</p>
</td>
</tr>
</table>
</td>
<td width="50%">
<table border="0" align="center" cellpadding="5" cellspacing="0">
<tr>
<td style="text-align:center">
<p>content</p>
</td>
</tr>
</table>
</td>
</tr>
</table>
</center>
Let me know what you think.
