Now the background color changes after the mouse is moved to the menu, and returns to the original color after the mouse is moved or clicked. How to implement it now? The background color after clicking is the background color of the menu when the mouse is moved, and another menu is clicked. When the background color of the previous menu returns to the original color.

<h2>帝王槌</h2><br/>
立剑赏月意惆怅,袖饰刀,衣披霜,傲视雾丸,徒手战扶桑.<br />
问津终寻帝王陵,黑影没,尸满岗,惟见逆鲮露寒光. <br />
须发苍,气轩昂,三尺银狼,破风动八方. <br />
依身紧握噬魂枪,饮虎血,豪万丈.惟有千年我故乡!

<h2>玉女枪法</h2><br/>
曾经有个梦想：驰骋江湖，快意恩仇。<br />
曾经有份愿望：千里追凶，十步溅血。<br />
曾经有腔豪情：奇功盖世，名冠武林。<br />
曾经有种期盼：烛影摇红，衣袖添香。

<h2>黑沙刚体</h2><br/>
赵客缦胡缨，吴钩霜雪明。银鞍照白马，飒沓如流星。
十步杀一人，千里不留行。事了拂衣去，深藏身与名。
闲过信陵饮，脱剑膝前横。将炙啖朱亥，持觞劝侯嬴。
三杯吐然诺，五岳倒为轻。眼花耳热后，意气素霓生。
救赵挥金锤，邯郸先震惊。千秋二壮士，烜赫大梁城。
纵死侠骨香，不惭世上英。谁能书阁下，白首太玄经。

<div style="display:none">
<h2>不羁浪人枪</h2><br/>
素手相牵，斜辉入眼帘，一轮逍遥自在间，醉了山水闲。<br />
沙漠绿水涟，鱼游浅底，明眸一水天。<br />
爱在村友相谈，开心点点，笑语连连，率性夜无眠。<br />
月在西边，风乱星寒，辗转醇香旧事，蛾儿曼舞灯前。
