[Title decapitalized. Don’t yell here.]

HEY, my site is https://mercuriproject.com running Twenty twelve

I want all text on my site white, but something I added also changed the white in my dashboard:

here is the coding I have in my CSS manager:

#page, #site-generator {
background-color: transparent;
}

#.post-meta {
    display:none;
}
.entry-meta {display:none !important;}

.site {
    margin: 0 auto;
    max-width: 108.5714rem;
    overflow: hidden;
}
.site-info {
   display: none;
}

.entry-content img, .comment-content img, .widget img, img.header-image, .author-avatar img, img.wp-post-image {
    border-radius: none !important;
    box-shadow: none !important;
}

a,
a em,
a strong {
color: #ffffff;
outline: none;
}
a:focus,
a:active,
a:hover {
color: #ffffff;
}
.site-header {
    margin-top: -50px;
    padding: 0;
}

.main-navigation {
	position: relative;
}
.main-navigation div {
	display: inline-block;
	margin: 0 auto;
	margin-right: -40px;
}
.main-navigation ul.nav-menu,
.main-navigation div.nav-menu > ul {
	border: none;
}

.site-content article {
-moz-hyphens: auto;
border-bottom: 4px double #000000;
margin-bottom: 5.14286rem;
padding-bottom: 1.71429rem;
word-wrap: break-word;
}

#site-navigation {

footer[role="contentinfo"] {
   display: none;
}
