很簡單。找到他的主頁，如果你用的是google瀏覽器，鼠標右鍵點擊檢查-Sources->customcss

custom英文的意思就是定制的意思。這個就是了。

你可以把這些樣式 放到你後臺管理的頁面定制css代碼框裏面。

下面是我個人的CSS樣式：

/*可折疊的代碼區1背景色*/
.code {
    background-color: #f5f5f5;

}

/*代碼字體*/
.code pre {
    font-family: Consolas !important;
}

.code span {
    font-family: Consolas !important;

}

/*評論框*/
div.commentform textarea.comment_textarea {
    line-height: 2; /*外邊距*/
    color: #0d07effa;
    background: #dee7de;
    letter-spacing: 2px; /*字體間距*/
}

/*評論按鈕*/
.comment_btn:hover {
    height: 41px;
    width: 96px;
    margin: 2px;
    padding: 4px;
    line-height: 23px;
    background-color: lightslategray;
    border: outset #edb2b2 3px;
}

/*關註按鈕*/
#green_channel #green_channel_follow {
    background-color: #e33100;
    -webkit-animation-name: bigAssButtonPulse;
    -webkit-animation-duration: 1s;
    -webkit-animation-timing-function: linear;
    -webkit-animation-iteration-count: infinite;
}

/*好文要頂*/
#green_channel #green_channel_digg {
    background-color: #ff1493;

}

/*h2*/

#post_body h2 {
    font-size: 16px;
    font-weight: bold;
    line-height: 1.5;
    margin: 10px 0;
}
