I would like to add fonts to LibreOffice in order to match the fonts in my blog template. My OS is Windows 10.
Noting you have edited your question to tell that you are using Win 10: a web search will turn up many answers on how to install fonts in Windows. It isn’t a LibreOffice function - LO simply uses the fonts provided by your OS.
You could also use the search above for e.g. add fonts to see similar questions that have been asked here.
Add the fonts to your operating system - how this is done depends on the OS which you haven’t mentioned - then restart LibreOffice so it will see the fonts you have added.
