It still isn't working. So I have decided that I might as well just create the css-rules myself. Lol.

Again, thank you for your help @jan_blaha :)

Oh, I see. Will it work if I customize the bootstrap that I am downloading and remove all the media queries? All that I need is just the grid-system of bootstrap to properly layout the report that will be generated.

By the way, thanks for the quick reply @jan_blaha :)

I'm trying to integrate the Bootstrap library to a template but to no avail it doesn't work. I tried the following methods:

1. Import the bootstrap cdn
2. Copy the whole bootstrap css and create a file in the assets folder
3. Put the whole bootstrap css declaration in the <style> tag in the header

It still isn't working for me. Is there a way for me to use this library? Thank you in advance
