sermonspeaker.css

Hi, i have added some lines in .css file, but after update of component i always lost it.
Where can i put .css file?

You have several options here, changing the file directly is the worst one

Best way is if your template allows to add some custom CSS code. If so, use that.

If not, you can override the CSS file from SermonSpeaker in your template directory. That is done by copying the file to /templates/your_template/css/com_sermonspeaker and make the needed changes there. That way Joomla will pick up your file instead of the one shipped with SermonSpeaker. That means you may have to track changes to the original file and add them to your copy if needed.

Another option would be to use a modul/plugin to add CSS to the site. There are several such extensions listed here: extensions.joomla.org/extensions/style-a-design/templating

Thanks for your answer. It's works. Great.
But another question.
I have added some lines to file extnewline.php. Where i have put it?
I have copied it in template/html/com_sermonspeaker/ but it does nothing.

There are some docs about layout here: sermonspeaker.net/documentation/layouting.html
