Pure CSS-Based Dropdown Menu Creation
In web development, dropdown menus are a common UI element used to organize and present choices logically. If you desire a dropdown menu without relying on external frameworks or JavaScript, pure CSS can deliver a suitable solution.
Pure CSS Dropdown Menu Implementation
To construct a purely CSS-based dropdown menu, follow these steps:
- HTML Structure: Define an unordered list (<ul>), with each list item (
- ) representing a menu item. Inside the list items, nest other unordered lists for submenus.
- Styling: Use CSS to style the menu. Set the ul to have no bullets, no margins, and a horizontal alignment. Position the li elements inline-block for horizontal alignment.
- Dropdown Visibility: To toggle the visibility of submenus, use the :hover pseudo-class on list items. When a list item is hovered over, its submenu (ul) becomes visible.
- Menu Appearance: Customize the appearance of menu items, submenus, and links using CSS properties like background-color, color, and padding.
Example Code
The following code snippet provides an example of a pure CSS-based dropdown menu:
HTML:
<ul>
CSS:
ul {
font-family: Arial, Verdana;
font-size: 14px;
margin: 0;
padding: 0;
list-style: none;
}
ul li {
display: inline-block;
position: relative;
}
li ul {
display: none;
}
ul li a {
display: block;
text-decoration: none;
color: #ffffff;
border-top: 1px solid #ffffff;
padding: 5px 15px 5px 15px;
background: #2C5463;
margin-left: 1px;
white-space: nowrap;
}
ul li a:hover {
background: #617F8A;
}
li:hover ul {
display: block;
position: absolute;
}
li:hover li {
float: none;
font-size: 11px;
}
li:hover a {
background: #617F8A;
}
li:hover li a:hover {
background: #95A9B1;
}

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
