Abstract: With the rapid development of the mobile Internet, responsive design has become an important part of web development important technology. This article will introduce several common types of responsive layouts and understand their advantages and disadvantages through specific code examples.
1. Fixed Width Layout (Fixed Width Layout)
Fixed width layout is one of the most basic layout types, which specifies the width of the web page to be a fixed pixel value. For example:
.container {
width: 960px;

.container {
width: 100%;
max-width: 1200px;
margin: 0 auto; /* 居中对齐 */
}Advantages:
- Can adapt to the screen size of various devices and provide a better user experience.

.container {
display: flex;
justify-content: space-between; /* 元素间间距均分 */
align-items: center; /* 垂直居中对齐 */
}Advantages:
- The size and position of elements can be dynamically adjusted according to the screen size, providing better adaptability.

Disadvantages:
- The implementation is complex and requires understanding of how to use flexbox and grid.
- The compatibility is poor, and some old browsers do not support flexbox and grid.
To sum up, different responsive layout types have their own advantages and disadvantages. Developers need to choose the appropriate layout type based on project needs and user experience. In order to better understand the various layout types, the following will demonstrate their differences through a simple code example:
<!DOCTYPE html>
<html>
<head>
<style>
.container {
width: 960px;
margin: 0 auto;
background-color: lightgray;
padding: 20px;
}
.box {
height: 200px;
background-color: darkgray;
margin-bottom: 20px;
}
@media screen and (max-width: 768px) {
.container {
width: 100%;
background-color: lightblue;
padding: 10px;
}
.box {
height: 100px;
margin-bottom: 10px;
}
}
</style>
</head>
<body>
<div class="container">
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</div>
</body>
</html>The above code demonstrates a web page layout containing three boxes. When the screen width is less than or equal to 768 pixels, the container width becomes 100%, the background color becomes light blue, and the box height is halved. This simple example shows the different effects of fixed-width layout, fluid layout, and flexible layout.
Summary:
Responsive design is a mobile-first design concept, and different layout types have different advantages and disadvantages. Fixed-width layout is simple and has good compatibility, but the display effect is not good on different screens; fluid layout has strong adaptability and good user experience, but the page content may be displayed too wide on large-screen devices; elastic layout is a compromise A layout type that has the advantages of fixed-width layout and fluid layout, but is complex to implement and has poor compatibility. Developers need to reasonably select the layout type based on specific project needs, and flexibly use corresponding technologies to achieve responsive layout in actual development.
