Disabling the <header> tag with CSS while keeping it visible on the webpage

Is there a way to disable the <header> using CSS without hiding it? I am unable to find any disabled attribute that can be added to the element. The header contains dropdowns and buttons.

To disable the entire page, I used JQuery to add a div with a specific class.

<div class="modalOverlay"></div>

The associated CSS style is as follows:

.modalOverlay {
    position: fixed;
    width: 100%;
    height: 100%;
    top: 0%;
    left: 0%;
    right:0%;
    bottom : 0%;
    background-color: rgba(0, 0, 0, 0.1); /* black semi-transparent */
}

This style applies to the entire page except for the elements within the header tag. How can I disable those too, preferably with CSS so I can easily add or remove the class as needed?

UPDATE:

<header>
    <nav class="navbar navbar-default">
        <a class="navbar-brand" href="#"> Title </a> <a
            class="toggle-nav btn pull-left" href=""> <i class="icon-reorder"></i>
        </a>
        <ul class="nav">
            <li class="dropdown medium only-icon widget"><a
                class="dropdown-toggle" data-toggle="dropdown" href=""> <i
                    class="icon-rss"></i>
                    <div class="label">1</div>
            </a>
                <ul class="dropdown-menu">
                    <li><a href="">
                            <div class="widget-body">
                                <div class="pull-left icon">
                                    <i class="icon-user text-success"></i>
                                </div>
                                <div class="pull-left text">
                                    New User Added. <small class="text-muted">just now</small>
                                </div>
                            </div>
                    </a></li>
                    <li class="divider"></li>
                    <li class="widget-footer"><a href="">All notifications</a></li>
                </ul></li>
            <li class="dropdown dark user-menu"><a class="dropdown-toggle"
                data-toggle="dropdown" href=""> <img width="23" height="23"
                    alt="userName" src="assets/images/male_icon.png" />
                    <span class="user-name">Hi, Guest</span> <b
                    class="caret"></b>
            </a>
                <ul class="dropdown-menu">
                    <li><a href=""> <i class="icon-user"></i> Profile
                    </a></li>
                    <li><a href=""> <i class="icon-cog"></i> Settings
                    </a></li>
                    <li class="divider"></li>
                    <li><a href="" ng-click="logout()"> <i
                            class="icon-signout"></i> Sign out
                    </a></li>
                </ul></li>
        </ul>
    </nav>
</header>

Thank you.

Answer №1

One possible solution is to set the z-index value to 99.

.modalOverlay {
 position: fixed;
 width: 100%;
 height: 100%;
 top: 0%;
 left: 0%;
 right:0%;
 bottom : 0%;
 z-index:99;
 background-color: rgba(0, 0, 0, 0.1); /* creating a black semi-transparent overlay */
}

Answer №2

navigation{
  position: absolute;
  z-index: 80;
}

.overlayModal {
  z-index: 110;
}

Answer №3

Disabling elements in CSS is not possible in the same way as removing their functionality defined in HTML or programmed with JavaScript. Any attempts to disable elements may only affect mouse operations, not keyboard-based (or speech-based) use of controls and links.

To properly disable a control in HTML, you should set the disabled attribute or property on it, either in the HTML itself or using JavaScript. For a link, removing the href property is necessary (you can save its value to a data-href property if needed). To apply this across all controls and links within an element, JavaScript code that traverses the descendants of the element is required.

Answer №4

To ensure that the text remains visible while preventing interactions with the content inside a div and even <a> elements, you can apply the CSS property pointer-events:none;. For a demonstration, check out this DEMO.

.modalOverlay {
    position: fixed;
    width: 100%;
    height: 100%;
    top: 0%;
    left: 0%;
    right:0%;
    bottom : 0%;
    background-color: rgba(0, 0, 0, 0.1); /* black semi-transparent */
    pointer-events:none; /*This is the KEY*/
}
