Until a WordPress plugin is installed or child theme is created to override the current text color here are links to a Chrome and Firefox plugin that will allow you to override the site’s CSS when your browser renders “atheistzone.com” and every url within the domain.
Firefox:
1. Download the “Stylish” add-on from https://addons.mozilla.org/en-us/firefox/addon/stylish/
2. After installation, restart your browser and go to atheistzone.com
3. In the top right you should see a small “S” icon. Click on that and go to Write new style > For atheistzone.com
4. In the new tab enter this code:
@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain(“atheistzone.com”) {
* {font-family: “UTF-8”
!important; color:black !important}
}
5. Give it a name and save it.
6. Go back to your atheistzone.com tab and refresh.
Chrome:
1. Download the “Stylish” add-on from: https://chrome.google.com/webstore/detail/stylish/fjnbnpbmkenffdnngjfgmeleoegfcffe
2. After installation go to atheistzone.com
3. In the top right you should see a small “S” icon. Click on that and then click “Write style for: atheistzone.com”.
4. In the new tab enter this code:
* {font-family: “UTF-8”
!important; color:black !important}
5. Give the style a name and save it.
6. Go back to your atheistzone.com tab and refresh.
Note: You don’t have to use UTF-8. You could use “Comic Sans MS” or any other font your browser supports.
