Two CSS styles with a passion for the base

Custom blog style, the code snippet Line-height inherited style post Line-height, the interval is too large, decided to reduce the point, CSS has played for several years, it is very easy to feel this thing. Then, it was tragic for a long time, originally custom style sheet for

. Headermaintitle{font-family:"XXFarEastFont-Xingkai", Verdana,arial,helvetica,sans-serif;font-size:50px;}. Headerdis{font-family:"XXFarEastFont-Xingkai", Verdana,arial,helvetica,sans-serif;font-size:20px;text-align:Center;}Body{font-size:12px;}. Mysearch{Display:None;}. Postcon{font-size:12px; }. C_b_p_desc{Line-height:24px;}. Day{Margin-bottom:0;}. Day Center{Display:None;}. Postseparator{Display:None;}#left_border{Height:Auto;}#footer{Display:Block;text-align:Center;padding:30px 0px 15px 0px; } . Post { font-size:12px;  Line-height:26px;}#cnblogs_post_body P{margin:0;padding:0;}#cnblogs_post_body a{Color:Blue;}#author_profile{Display:None;}Div.commentform textarea{width:100%;}. Commentbox_title{width:100%;}#commentbox_opt{text-align: Right;}#ad_under_post_holder{Display:None;}. C_ad_block{Line-height:20px;}#site_nav_under, #blog_news_kb{Display:None;}. Feedbackitem{Border-bottom:1px dashed #ccc;}. Feedbackcon{background:None;}. Posttitle{padding:22px 15px 10px 28px;}. Post pre {line-height :16px;}

I think it is normal, the last three lines rewrite the pre row height, it should be smooth. But... Actually did not work, puzzled for a long time, has been unable to solve.

Just after watching TV, bored, decided to continue to toss, but, dead or alive or not, the review element, the Line-height property can see is the style post, I have rewritten the post style, but then to rewrite the post of the pre row height why not????

Then, I guess since it is the post style, I follow the emphasis on writing the pre-line high, it should be a little problem ... Then moved to post style, refresh ... Hey???? All right!!!!

Just move the last style of the pre-line to the style post, how can it work again?????

No solution .... Really good friends ah, separate still not work!
