` inside like you do for regular html pages
### Some strange things that happened to me
#### Svg & Png story
Gmail did not wanted .svg type images (Outlook had no problem with them). I had to use .png instead. But the thing is .png with transparency rendered blurry for some reason, putting a background color solved the problem. But I had some problem with simple white background, for some reason... Turns out that it might also be that my file wasn't big enough in resolution, but that's not sure either.
#### True black
For a strange reason, the text of my email where transformed from regular black to greyish color, on both Outlook & Gmail. `#000000;`, `#000;`, `rgb(0,0,0);` didn't work. The problem was solved by simply putting `color:'black';` manually on each `
` with text in it. Leaving empty font color to have the default black didn't work either.
#### The `color: #000001;` secret
Gmail tends to override the color of links if you set them with a `color:#000000;` / `"black"`. You can use a slightly not full black to avoid that, like `#000001;`. Possibly compatible with previous point.
#### Inliners not Gmail compatible
Online inliners like [campaign monitor](https://inliner.cm/) and [Mailchimp](https://templates.mailchimp.com/resources/inline-css/) one's do a half good job, you'll need to correct things by hand. For example when declaring a font this way : `font-family 'MyFont';` it will be inlined `style="font-family:"MyFont";"` So you have double quotes inside double quotes, And Gmail will remove everything. You should then, by hand change that to `style="font-family: 'Myfont';"`
#### Gmail is sensitive
You should *always* put spaces after ";" "," and ":". So from this : `"font-family:'Arial','Calibri';color:#000001;"` you should make it like that : `"font-family: 'Arial', 'Calibri'; color: #000001;"`
#### Gmail is *really* sensitive
You should *never* have spaces inside quotes. When declaring fonts, things like `'My Font'` will be stripped out by Gmail (and all styling with it, remember), but things like `'My-Font'` or `'MyFont'` work well.
