Question

I'm creating an HTML newsletter. I'm using nested array. I have two question : how do I import font? Because #import and #font-face are not working on my newsletter (but works on simple html)
And the second is this :
How can I " vertical align middle " 2 span with different font-size ? It's working on simple html but not on the newsletter...

Answer 1

As I mentioned in my comment, Outlook does not work with all web-fonts like Google fonts. You don't include full paths to resources so there is no way for us to test what you are doing and look for a solution.
My first suggestion is to open your email in a web browser and test to see if it works at all. If it does, then I suggest testing what you are doing in an Apple or IOS email client, since they seem to work well with web fonts. If it works, you know you have things coded correctly.
Generally an HTML document wih a web font needs a link to that font and applied in a class for use in the document.
You should have a link like this:
<style>
#import url("https://www.site.fr/.../GT-Walsheim-Regular.ttf");
</style>
Or this:
<link href="https://use.typekit.net/jqe0zpu.css" rel="stylesheet">
Next, you need to find some way to get the font out into the document.
<style>
.classname {
font-family: GT-Walsheim, Arial, sans-serif;
}
</style>
In the last example, I added Arial as a fallback font that is pretty web-safe because Walsheim is not going to work with Gmail and most likely not work with Outlook 2007, 2010, 2013-2019.
Finally, apply the classname:
<p class="classname">Hello</p>
You could go fancy and add in inline styles as well:
<p class="classname" style="font-family: GT-Walsheim, Arial, sans-serif;">Hello</p>
This is a very basic plan on how to work with web fonts in email.
Good luck.

Here is a simpler method of using div tags:
<style>
#import url('https://fonts.googleapis.com/css?family=Open+Sans');
#fevrier {
background: #00436f;
border-radius: 10px;
font-weight: bold;
color: #ffffff;
display: inline-block;
font-family: sans-serif;
text-align: center;
text-decoration: none;
width: 180px;
font-size: 16px;
font-weight: bold;
text-transform: uppercase;
vertical-align: middle -webkit-text-size-adjust:none;
padding-top: 25px;
padding-bottom: 25px;
}
#fevrier .text {
font-size: 12px;
font-weight: bold;
text-transform: uppercase;
}
</style>
<div id="fevrier">
15 <span class="text">FÉVRIER </span>
</div>
