html, body {background-color: #e0dcc0!important;} html, body {font-size:100%} div.post {background-color: #e0dcc0!important;} div.main {background-color: #e0dcc0!important;} div#content {background-color: #e0dcc0!important;} div.showBox {background-color: #e0dcc0!important;} div.WB_feed {background-color: #e0dcc0} div.blog_main{background-color: #e0dcc0!important;} DIV.iteye-blog-content-contain{background-color: #e0dcc0!important;} TEXTAREA#source.goog-textarea {background-color: #e0dcc0!important;} div.p_content{background-color: #e0dcc0!important;}/*tieba*/ DIV.j_lzl_c_b_a.core_reply_content{background-color: #e0dcc0!important;}/*tieba*/ div.entry-content{background-color: #e0dcc0!important;}/*howtodoinJava*/
