Hi Claudia,
I understand what you’re referring and it’s true there are few options. It’s a theme framework a bit different from another bloated theme which makes X theme more faster. For example, let’s say you only need to change a simple color and just once, but the theme has a full-blown feature for color picker and layout library running for every page load. It’s going to be slow for the simple change that is meant to be permanent until the site is redesigned. A theme framework is usually meant for site development without being bloated with features meant to be used once or a few times. And manually added CSS are permanent which make sit faster.
This will help too for creating your own preferred CSS https://developers.google.com/web/tools/chrome-devtools/beginners/css
Before we continue, please disable your optimization plugin first so I know where the CSS is coming from. And please start a new thread for each issue and question for better tracking.
For clarification, the blog title you’re referring is the post title right? Please go to Theme Options > Typography and change the heading and links color, and body color. It will change all headline and text color including the post meta. Assuming the CSS is coming from the theme.
As for the widget, it could be this
.widget ul li, .widget ol li {
background-color: #000;
}
There are multiple instances of it so I can’t really verify its origin. So please deactivate any optimization plugin, it’s only recommended once you’re finished developing your site.
Thanks!
