changing template's font size problem

[alaa.]

hello ..

Im having a problem with changing the fonts on my site..

the steps i did was:
1- login to cpanel and open file manager.
2- open css file
3-choose styles.css and edit it ..

when i edit the size of the text font .. everything seems to be fine and updated on the site ..
but whenever i make any changes in my sitebuilder wizerd and publish my site .. all the fonts and text effects that i had updated on the cpanel are set back to default template fonts..

i learned programing by my own .. so i dont know where to find the default file of the text for each template to change the it to the font size that i want because most of the templates has very small fonts and i want to change it ..

so if anyone can help me to locate the default template file to modify it and set the default values .. i will apreciate it

thanx in advance

I have the exact same question - any way to edit site content and publish updates to the site without affecting styles.css?
