# Fix the auto rendering issue of Mathjax with LaTex

Recently, I build my own About website with blog posts based on al-folio. However, I find the Kramdown cannot render the conventional LaTex math code, like inline math  or  and display math  and .

The default setting of the kramdown renders the inline and display math with , which is different with LaTex and markdown. Mathjax Docs gives the solution to add the single dollar configuration. You only need to add below codes to _includes/mathjax.html:

Then you can use the inline math  and display math  in your posts.

Then you can use LaTex code to render your post.

Here is an example:

It shows on the website:

$R_{i t}=\beta_{i}^{\prime} \lambda_{t}+\alpha_{i t}, \quad i=1,2, \cdots, N$

Here is another example of inline math $R_{i t}=\beta_{i}^{\prime} \lambda_{t}+\alpha_{i t}, \quad i=1,2, \cdots, N$.

It will be rendered as $$R_{i t}=\beta_{i}^{\prime} \lambda_{t}+\alpha_{i t}, \quad i=1,2, \cdots, N$$.
