Given some HTML string, Using, JQuery how can I search for all the styles containing for example, font-family:courier 

```
<span style='font-family:courier;'>
<p style='font-family:courier;'>

```

and change it to font-family:courier new ?, resulting:

```
<span style='font-family:courier new;'> 2</span>
<p style='font-family:courier new;'>

```
