I must just be crazy from staring at my computer screen but if you look at the class verticalmembersmenu in the CSS, I can't for the life of me figure out why I can't get the border around the div.

回答1:

You are using HTML style comments in your CSS, that seems to be breaking the rendering, take a look at http://jsfiddle.net/4HnKs/3/

u can give inline style to div as

 <div class="verticalmembersmenu" style = "border:1px solid black;">

.verticalmembersmenu ul{
list-style:none; border:1px solid black;
}

回答3:

please give the border in ul tag.

.verticalmembersmenu ul{
    list-style:none; border:1px solid black;
    }

It took me a while to find, but the problem actually has to do with your css formatting. The css doesn't recognize html comment tags, but instead uses /* */.

 <!--MEMBERS LAYOUT START -->
.verticalmembersmenu {
    height:300px;
    width:300px;
    border:1px solid black;
}

.verticalmembersmenu ul{
    list-style:none;
}


<!--MEMBERS LAYOUT END -->
