/* 背景區塊的整個存在意義就是「滿版底色」，但它跟其他內容區塊一樣是.site-main的普通子元素，
   會被.site-main自己的內距(版面設定INDEX_CSS設的，例如70px 60px)往內推，光靠外觀設定的
   寬度100%只會等於「填滿扣掉內距後的內容寬度」，永遠到不了畫面兩側——這裡讓它自己跳出
   .site-main的內距，撐到真正的視窗邊緣(經典的calc(50%-50vw)滿版技巧)。要注意這個算法假設
   .site-main本身置中滿版(沒有左右側邊欄)，如果之後有頁面同時開左右區塊又用背景區塊，
   兩側可能會蓋出去，屆時要另外處理。
   加!important是必要的：外觀設定存出來的BOX_STYLE是用#cb-{id}這個ID選擇器蓋在<style>裡
   (見block_render.php的block_box_style_css())，specificity比這裡的class選擇器高，
   使用者在外觀設定隨手填的「寬度100%」（或完全沒填，瀏覽器預設width:auto也是抓外層內距
   算出來的寬度）都會贏過這條規則，滿版效果就失效──但「滿版」本來就是這個區塊類型唯一
   的用途，不該讓外觀設定的寬度欄位意外蓋掉，所以在這裡用!important鎖死 */
