Few days ago & still now I’ve facing serious problem. I’m customizing my own blogger template. Everything works ok but problem in CSS code. When I Copy Paste my CSS code in blogger template its saved but when I visit my blogger its nothing changed. I’m shocked!!! After that I again go to my blogger template and checked the CSS code. No CSS Code here which I’ve saved previously. Finally I think that may be my CSS code line is huge so I compressed my CSS code and save it again But Same result. So anybody can help me how I resolve my problem!!!
Try adding the css externally and check whether it works
<link rel="stylesheet" href="your-css-url.css">
