Creating Inner Text Shadow with CSS
You're seeking a technique to cast a blurry, inner shadow on text within a web page. You've explored the box-shadow property but realized its limitations to inner shading. This article aims to guide you with a novel technique utilizing pseudo-elements to achieve your desired effect.
The Pseudo-Element Trick
In CSS, pseudo-elements (:before and :after) enable the creation of additional content within an element. Here's a clever application of these elements to create the inner shadow:
- Content: Assign the title attribute on your text element with the desired inner shadow content. This content will be used by the pseudo-elements.
- Pseudo-Elements: Add two pseudo-elements (:before and :after) to the text element. Assign the same content as the title attribute and give them a slight offset position (e.g., 1px left and 1px top) relative to the original text.
- Color and Opacity: Adjust the color and opacity of the pseudo-elements to create a translucent blurry shadow. For instance, rgba(255, 255, 255, .1) would create a white shadow with 10% opacity.
- Z-Index: Position the pseudo-elements behind the original text using z-index and negative values to ensure they're rendered behind the text.
Example Code
Below is an example code that demonstrates the technique:
<code class="css">.depth {
display: block;
padding: 50px;
color: black;
font: bold 7em Arial, sans-serif;
position: relative;
}
.depth:before,
.depth:after {
content: attr(title);
padding: 50px;
color: rgba(255, 255, 255, .1);
position: absolute;
}
.depth:before {
top: 1px;
left: 1px
}
.depth:after {
top: 2px;
left: 2px
}</code>
<code class="html"><h1 class="depth" title="Lorem ipsum">Lorem ipsum</h1></code>

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.
