Hide author in posts and change background color of comment boxes

Hello
I need help with my posts
I want to hide the author in post, the date its ok, but I don´t need the author to appear…How i do that?
the other thing on posts is the boxes bellow the content (comments and post navigation) are white with gray letters, i need them in reverse, i mean, gray boxes with gray fonts…Is that possible to change?

this is one of the posts entries http://laovejanegra.org/el-caso-del-cadaver-desconocido/

thanks a lot !!

Hi,

You can hide author link on single posts with css code below:

body.single-post span.byline span.author.vcard {
    display: none;
}

and for input boxes and navigation use this code:

.post-navigation {
    background-color: #443f3f;
}

.post-navigation a {
    color: #c7c7c7;
}

.post-navigation .nav-previous:hover span, .post-navigation .nav-next:hover span {
    color: #fff;
}

select, textarea, input[type="text"], input[type="password"], input[type="datetime"], input[type="datetime-local"], input[type="date"], input[type="month"], input[type="time"], input[type="week"], input[type="number"], input[type="email"], input[type="url"], input[type="search"], input[type="tel"], input[type="color"] {
    color: #fafafa;
    background-color: #767676;
    border: 1px solid #767676;
}

Apply the code from Appearance > Customize > Additional CSS field and off course adjust color further if needed. Result with that code should look like this https://www.screencast.com/t/1JiNGBpRV2y
