How easily change font size in spacemacs?
<p>How do change the font size in spacemacs? Do I need to download additional packages such as source code font?</p>

<p>I tried changing the font size in the configuration file, but the font size does not change. I am having trouble installing source code font, because the font paths are not registered correctly. The fonts were installed via the instructions provided by open source Adobe. Is there an easier way to do such a simple task in spacemacs?</p>
