Rounded corners in outlook without images

I can create rounded corners in many clients with

style="-moz-border-radius: 15px; border-radius: 15px;"

However this CSS does not create rounded corners in Outlook. Is th开发者_如何学运维ere any easy way to create rounded corners without images in Outlook?

This code produces buttons with rounded corners in Outlook 2010 using the Outlook conditional comments () and VML:

    <div>
    <!--[if mso]>
    <v:roundrect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" href="http://www.EXAMPLE.com/" style="height:40px;v-text-anchor:middle;width:300px;" arcsize="10%" stroke="f" fillcolor="#d62828">
        <w:anchorlock/>
        <center style="color:#ffffff;font-family:sans-serif;font-size:16px;font-weight:bold;">
            Button Text Here!
        </center>
    </v:roundrect>
    <![endif]-->
    <!--[if !mso]> <!-->
    <table cellspacing="0" cellpadding="0"> <tr>
        <td align="center" width="300" height="40" bgcolor="#d62828" style="-webkit-border-radius: 5px; -moz-border-radius: 5px; border-radius: 5px; color: #ffffff; display: block;">
            <a href="http://www.EXAMPLE.com/" style="color: #ffffff; font-size:16px; font-weight: bold; font-family:sans-serif; text-decoration: none; line-height:40px; width:100%; display:inline-block">
                Button Text Here!
            </a>
        </td>
    </tr> </table>
    <!-- <![endif]-->
</div>

Tested in Outlook 2010 and major browsers only, not OWA, Outlook.com or any mobile browsers. It's worth a closer look. Credit where due -- http://www.industrydive.com/blog/how-to-make-html-email-buttons-that-rock/

http://www.campaignmonitor.com/css/ displays all css supported in major email clients. Rounded borders didn't even make it to the list. On the page there is a link to a full PDF, which notes that border radius is ONLY supported in Thunderbird 2

please note that you have to embed the styles in the html elements to support a broad range of email clients

You can find the full list of supported HTML elements and CSS styles in the following series of articles:

I recommend using https://buttons.cm/ which will generate something like this:

<div>
  <!--[if mso]>
    <v:roundrect 
      xmlns:v="urn:schemas-microsoft-com:vml" 
      xmlns:w="urn:schemas-microsoft-com:office:word" 
      href="http://TEST.com" 
      style="height:40px;v-text-anchor:middle;width:200px;" 
      arcsize="10%" 
      stroke="f" 
      fillcolor="#B7D636">
    <w:anchorlock/>
    <center>
  <![endif]-->
      <a href="http://TEST.com"
         style="background-color:#B7D636;
                border-radius:4px;
                color:#ffffff;
                display:inline-block;
                font-family:sans-serif;
                font-size:13px;
                font-weight:bold;
                line-height:40px;
                text-align:center;
                text-decoration:none;
                width:200px;
                -webkit-text-size-adjust:none;">
              TEXT
            </a>
  <!--[if mso]>
    </center>
  </v:roundrect>
<![endif]-->
</div>

Note that the most bulletproof kind of button is a button that is an image. That way the whole element will be clickable, it will survive email forwarding, and all email clients will support it without bugs.

Further to @VanAlberts answer which shows Eli Dickinson's great work. Here is a link to Eli's git repo https://gist.github.com/elidickinson/9424116

I thought I would share my improvement to Eli's code which allows for dynamic width button based on the text inside.

I found this https://litmus.com/community/discussions/538-vml-outlook-07-10-13-unwanted-20px-padding-at-the-bottom which shows how to use mso-fit-shape-to-text:true

And this https://litmus.com/community/discussions/1269-flexible-multi-line-bulletproof-buttons which shows how to avoid some unwanted padding.

This is my end result

<div>
<!--[if mso]>
  <v:roundrect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" href="http://www.EXAMPLE.com/" style="mso-wrap-style:none; mso-position-horizontal: center" arcsize="10%" strokecolor="#0368d4" strokeweight="1px" fillcolor="#d62828">
    <v:textbox style="mso-fit-shape-to-text:true">
        <center style="color:#ffffff;font-family:sans-serif;font-size:16px;font-weight:bold;">Button Text Here!</center>
    </v:textbox>
  </v:roundrect>
  <![endif]-->
  <![if !mso]>
  <table cellspacing="0" cellpadding="0"> <tr> 
  <td align="center" width="300" height="40" bgcolor="#d62828" style="-webkit-border-radius: 5px; -moz-border-radius: 5px; border-radius: 5px; color: #ffffff; display: block;">
    <a href="http://www.EXAMPLE.com/" style="font-size:16px; font-weight: bold; font-family:sans-serif; text-decoration: none; line-height:40px; width:100%; display:inline-block">
    <span style="color: #ffffff;">
      Button Text Here!
    </span>
    </a>
  </td> 
  </tr> </table> 
  <![endif]>
</div>

Seems to work great in outlook 2016 which uses word to render HTML

I suggest to just not use rounded corners.. after long times of testing, both with Litmus, on multiple clients - rounded corners using the ways suggested such as:

<div>
<!--[if mso]>
  <v:roundrect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" href="http://www.EXAMPLE.com/" style="mso-wrap-style:none; mso-position-horizontal: center" arcsize="10%" strokecolor="#0368d4" strokeweight="1px" fillcolor="#d62828">
    <v:textbox style="mso-fit-shape-to-text:true">
        <center style="color:#ffffff;font-family:sans-serif;font-size:16px;font-weight:bold;">Button Text Here!</center>
    </v:textbox>
  </v:roundrect>
  <![endif]-->
  <![if !mso]>
  <table cellspacing="0" cellpadding="0"> <tr> 
  <td align="center" width="300" height="40" bgcolor="#d62828" style="-webkit-border-radius: 5px; -moz-border-radius: 5px; border-radius: 5px; color: #ffffff; display: block;">
    <a href="http://www.EXAMPLE.com/" style="font-size:16px; font-weight: bold; font-family:sans-serif; text-decoration: none; line-height:40px; width:100%; display:inline-block">
    <span style="color: #ffffff;">
      Button Text Here!
    </span>
    </a>
  </td> 
  </tr> </table> 
  <![endif]>
</div>

Will break on GMAIL when forwarding, when forwarding this type of code to GMAIL - it will try to re-create it because it won't contain the condition any longer and will generate the following code as example:

<div style="margin-top:36.0pt">
   <p class="MsoNormal" align="center" dir="RTL" style="text-align:center;direction:rtl;unicode-bidi:embed">
      <span dir="LTR" style="font-size:11.5pt;font-family:&quot;Arial&quot;,sans-serif;color:#2d3b4a">
         <u></u>
         <span>
            <map name="m_3406853463519709989_MicrosoftOfficeMap0">
               <area shape="Polygon" coords="38, 2, 13, 12, 3, 37, 13, 62, 38, 72, 228, 72, 253, 62, 263, 37, 253, 12, 228, 2, 38, 2" href="https://local.greeninvoice.co.il/app/account/verify?key=001dEbYWSscdPxI8xt6BcS%2B%2BrA%3D%3D" target="_blank" data-saferedirecturl="https://www.google.com/url?hl=en&amp;q=https://local.greeninvoice.co.il/app/account/verify?key%3D001dEbYWSscdPxI8xt6BcS%252B%252BrA%253D%253D&amp;source=gmail&amp;ust=1520336994067000&amp;usg=AFQjCNE1iYP97qNrlsCccYFgDyRW3iVPRw">
            </map>
            <img border="0" width="264" height="74" src="?ui=2&amp;ik=4e1d22bf20&amp;view=fimg&amp;th=161f5fb79e36447b&amp;attid=0.1&amp;disp=emb&amp;attbid=ANGjdJ_3ejUStIrGp0uslTPSXPSph1LGDDnyTH2gHxWhcMpCHN_CjO4ZYsqbvqZJ9gXCxQ7e3KHV2CAn0f-FWPYH7w7lTM9ym54909Upm-h_G9W--o_I431bc9U3icg&amp;sz=w528-h148&amp;ats=1520250594056&amp;rm=161f5fb79e36447b&amp;zw&amp;atsh=1" usemap="#m_3406853463519709989_MicrosoftOfficeMap0" alt="Rounded Rectangle: הפעלת החשבון " class="CToWUd">
         </span>
         <u></u>
      </span>
      <span lang="HE" style="font-size:11.5pt;font-family:&quot;Arial&quot;,sans-serif;color:#2d3b4a"><u></u><u></u></span>
   </p>
</div>

This as you can see will break the width, height, text, center of stuff and happens because VML is a proprietary Microsoft language and Outlook converts it to a map when forwarding
