Changing (back to default) font in ipython notebook

问题

I used the following code to change the font of my notebook:

<style>
div.text_cell_render {
font-family: "Times New Roman", serif, serif;
}
</style>

But, didnt like the outcome. I tried to change it back by:

<style>
div.text_cell_render {
font-family: "Arial", serif;
}
</style>

But this does not working. is it becuase Arial is not a serif? I tried different combinations but non worked...
