How to fix partial css substitution in Chrome extension?

Question

Browser extensions

In general, the bottom line is that you need to make your theme for the site. Styles corrected in real time yesterday, copied and pasted into the file specified in manifest.json, but faced with the fact that there is a partial substitution, and not a full one, as it was done. (I checked the styles through user css, everything is in order there).

Full manifest.json

{
    "manifest_version": 2, 
    "name":"L17-NightTheme",
    "version":"0.1",
    "description":"Demo plugin",
    "content_scripts":[
        {
            "matleague17hrus":["https://*.*.*/*"],
            "css":["ver.css"]
        }
    ],

    "web_accessible_resources": [
    "ver.css" 
]
}
