The lower part is using my own css. For the upper version, I have added bootstrap bootstrap css. As you can see this addition has totally messed up my original css despite the fact my own css comes last.
Question: How can I have bootstrap css included and also keep my original format?
FYI, I want to have bootstrap css included to use it fr some other bootstrap-specific functionality later on. This mean, I do not want to overwrite the added css but to keep my font formats as before.
The attached zip file is included in case you want to see more of it.
