Inline Typst might be the true strength of Kodama, as the designers have made great efforts to make it behave just like or at least very close to $\KaTeX$ inline formulas, so that the inline formulas written in Typst do not appear inferior when mixed with $\KaTeX$.
Inline Typst also uses link-like syntax, but in this case, no file is actually linked. The url part is used to specify the inline mode and the margin parameter. In most cases, users do not need to manually set the margin parameter to achieve a good presentation. The inline mode is a parameter designed for the convenience of the Markdown editor’s own preview feature. When the user enters math, the content of the text part is automatically enclosed with ${}$ before being compiled by Typst. Here are some examples:
[$x^2$](inline), x^2 is a valid formula for both $\KaTeX$ and Typst. In this case, the Markdown editor’s own preview feature can correctly display it as $x^2$. However, this example is so simple that there is no real reason to use Typst.
# is a frequently used character in Typst. If you still write ${}$ manually, it would lead to a poor preview experience in the editor. This is where the inline mode parameter math comes into play. Now you can write the first example as [x^2](inline-math).
Values of parameters are separated by -. The positions of math and margin are fixed, which means that if both parameters are present, you can only write margin after math. The margin is composed of text in the form of {x}-{y}, where x and y are any valid Typst length values, such as 0pt-2pt. When y is missing, y will adopt the value of x.
