Question

The content of my menu is concealed within a DIV. It may remain hidden or malfunction

I am in the process of creating master pages. In one of the master pages, I have implemented a dropdown menu using jQuery and CSS. While it works perfectly fine on some pages, it seems to be hidden on others that contain a div element. This is because the menu appears underneath the div, making it invisible on those particular pages. Below are the CSS and HTML code snippets.

body
{
    font-size: 0.85em;
    font-family: Verdana, Arial, Helvetica, sans-serif;
}

#nav, #nav ul
{
    margin: 0;
    padding: 0;
    list-style-type: none;
    list-style-position: outside;
    position: relative;
    line-height: 1.5em;
}

#nav a
{
    display: block;
    padding: 0px 5px;
    border: 1px solid #333;
    color: #fff;
    text-decoration: none;
     background: #595651;
}
...

Answer 1

Answer №1

To control the stacking order of elements in CSS, use the z-index property to determine which element should be displayed on top of others. Assign a higher value to the element you want to bring forward.

div { z-index: 500;}
ul { z-index: 1000;}

By setting these values, the ul element will appear above the div element if they overlap in the layout.

Best of luck!

Answer №2

You have the ability to specify a z-index value to control the stacking order of elements on the screen.

The z-index property determines the z-order of an element and its descendants. In cases where elements overlap, the z-order dictates which one appears in front of the other. Generally, an element with a higher z-index will cover up an element with a lower z-index.
