下拉菜单宽度排列(drop down menu width arrangement)

我有宽990px的网站，查看点击这里 。 只是我安装一个多层下拉菜单。 如果您在本网站看到我有6个类别的下拉菜单，之后一个空格。 我希望所有的类别不充分的空间安排。

我的CSS代码

  /* Page */
body,html,div,blockquote,img,label,p,h1,h2,h3,h4,h5,h6,pre,ul,ol,li,dl,dt,dd,form,a,fieldset,input,th,td{border:0;outline:none;margin:0;padding:0;}
ul{list-style:none;}

请建议我该如何解决这个问题..谢谢...

Answer 1:

.green ul.mega-menu li a {
float: left;
display: block;
color: black;
padding: 12px 38px 12px 25px;
background: url(images/bg_green.png) repeat-x 100% 0;
text-shadow: 1px 1px 1px white;
text-decoration: none;
width: 102px;
text-align: center;
}

而不是你已经

然后一点点的jQuery插件删除最后一个分路器

$('.green ul.mega-menu li:last-child a').css('background','none');

编辑更好看的按钮

.green ul.mega-menu li a .dc-mega-icon {
display: block;
position: absolute;
width: 8px;
height: 6px;
top: 18px;
right: 12%;
background: url(images/arrow.png) no-repeat 0 100%;
}

编辑答复使用下面的CSS

.green {font: normal 13px Arial, sans-serif; line-height: 16px;}
.green ul.mega-menu, .green ul.mega-menu, .green ul.mega-menu li {margin: 0; padding: 0; border: none;}
.green ul.mega-menu {background: #222 url(images/bg_green.png) repeat-x 0 -80px; width: 100%; height: 40px; border-right: 1px solid #44b3ff; border-left: 1px solid #44b3ff; position: relative;}
.green ul.mega-menu li {float: left; margin: 0; padding: 0; font-size: 13px; font-weight: bold;}
.green ul.mega-menu li a {float: left; display: block; color: black; padding: 12px 38px 12px 25px; background: url(images/bg_green.png) repeat-x 100% 0; text-shadow: 1px 1px 1px white; text-decoration: none; width: 102px; text-align: center;}

.green ul.mega-menu li.mega-hover a, .green ul.mega-menu li a:hover {background-position: 100% -40px; color: #000; text-shadow: none;}
.green ul.mega-menu li.mega-hover a .dc-mega-icon {background-position: 0 100%;}
.green ul.mega-menu li .sub-container {position: absolute; background: url(images/bg_sub_left.png) no-repeat 0 100%; padding-left: 20px; margin-left: -3px;}
.green ul.mega-menu li .sub {background: url(images/bg_sub.png) no-repeat 100% 100%; padding: 20px 20px 20px 10px;}

.green ul.mega-menu li .sub .row {width: 100%; overflow: hidden; clear: both;}

.green ul.mega-menu li .sub li.mega-hdr a.mega-hdr-a:hover {color: #fff; text-shadow: none;}
.green ul.mega-menu .sub li.mega-hdr li a {padding: 4px 5px 4px 20px; background: url(images/arrow_off.png) no-repeat 5px 8px; font-weight: normal;}
.green ul.mega-menu .sub li.mega-hdr li a:hover {color: #a32403; background: #efefef url(images/arrow_on.png) no-repeat 5px 8px;}
.green ul.mega-menu .sub ul li {padding-right: 0;}
.green ul.mega-menu li .sub-container.non-mega .sub {padding: 20px 20px 20px 0;}
.green ul.mega-menu li .sub-container.non-mega li {padding: 0; width: 190px; margin: 0;}
.green ul.mega-menu li .sub-container.non-mega li a {padding: 7px 5px 7px 22px; background: url(images/arrow_off.png) no-repeat 7px 10px;}
.green ul.mega-menu li .sub-container.non-mega li a:hover {color: #a32403; background: #efefef url(images/arrow_on.png) no-repeat 7px 10px;}

Answer 2:

你可以加

display: table; 

到UL和

display: table-cell; 

到LIS，而不是浮动。

这将导致类似：

.green ul.mega-menu {
    display: table;
}
.green ul.mega-menu li {
    display: table-cell;
    float: none;
}

BTW：你真的认为字幕是一个好主意？
