Changing the font in iPython notebook markdown cells

Question

I just wanted to change the default font in Ipython (1.0.0) notebook markdown cells to something else, and tried doing this using style tags in a markdown cell instead of going through the path of creating a custom.css. I do not know CSS, and my needs are very minimal. After some research, I found the following code snippet:

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

I applied the above CSS code to a markdown cell, however the font in the other markdown text cells did not change. Do I have to turn something on first? Below is how it looks like:

On Ubuntu this works:

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

The ... in your example indicate other possible options like listed e.g. in http://www.w3schools.com/css/css_text.asp

However, this CSS applies to all rendered cell text, ie. markdown and heading. If you want to format just the markdown text use .text_cell_render p {. The individual headings can be addressed with h1, h2, etc instead of p.
