<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<style>
img {
box-shadow: 10px 10px 10px rgba(0, 0, 0, .5);
/*考虑浏览器兼容性*/
-moz-box-shadow: 10px 10px 10px rgba(0, 0, 0, .5);
-webkit-box-shadow: 10px 10px 10px rgba(0, 0, 0, .5);
}
</style>
</head>
<body>
<img src="/static/imghw/default1.png" data-src="img/1.jpg" class="lazy" style="max-width:90%" / alt="How to set image shadow in css" >
</body>
</html>
2. Use filter:drop-shadow()# The ##filter attribute defines the visual effect (for example: blur and saturation) of the element (usually ).
drop-shadow() can set a shadow effect on the image. Shadows are composited underneath the image and can be blurred, offset versions of the matte that can be painted in a specific color.
Syntax:
filter:drop-shadow(h-shadow v-shadow blur spread color);Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<style>
img {
-webkit-filter: drop-shadow(10px 10px 10px rgba(0, 0, 0, .5));
/*考虑浏览器兼容性：兼容 Chrome, Safari, Opera */
filter: drop-shadow(10px 10px 10px rgba(0, 0, 0, .5));
}
</style>
</head>
<body>
<img src="/static/imghw/default1.png" data-src="img/1.jpg" class="lazy" style="max-width:90%" / alt="How to set image shadow in css" >

【Rust Self-study】Introduction
Apr 04, 2025 am 08:03 AM
1.0.1 Preface This project (including code and comments) was recorded during my self-taught Rust. There may be inaccurate or unclear statements, please apologize. If you benefit from it, it's even better. 1.0.2 Why is RustRust reliable and efficient? Rust can replace C and C, with similar performance but higher security, and does not require frequent recompilation to check for errors like C and C. The main advantages include: memory security (preventing null pointers from dereferences, dangling pointers, and data contention). Thread-safe (make sure multi-threaded code is safe before execution). Avoid undefined behavior (e.g., array out of bounds, uninitialized variables, or access to freed memory). Rust provides modern language features such as generics
