In actual development, we often encounter some problems related to responsive layout. This article discusses some common problems and provides corresponding solutions, accompanied by specific code examples.

Problem 1: The navigation menu cannot be displayed/displayed correctly

This is a very common problem, especially when the web page switches from desktop mode to mobile mode, the layout of the navigation menu is usually affected. Influence. One way to solve this problem is to use CSS media queries to style the navigation menu differently for devices with different resolutions.

Responsive layout usually uses multiple images of different sizes to adapt to devices with different viewport sizes. However, images that are too large will cause slow loading speeds and affect the user experience. To solve this problem, we can use the CSS property max-width to limit the maximum width of the image, and use an optimized version of the image to improve loading speed.

Problem 3: Page layout disorder

When a web page is displayed on different devices, changes in layout and style may cause page layout problems. To solve this problem, we can use CSS layout tools, such as flexbox or grid layout, to ensure that page elements are always arranged correctly.

}

.box {
  flex: 1 0 30%; /* 三栏布局 */
  /* 其他样式 */
}

/* 移动布局 */
@media (max-width: 768px) {
  .box {
    flex: 1 0 100%; /* 单栏布局 */
  }
}

The display size of the font may be different depending on the screen size of different devices. To solve this problem, we can use CSS’s @media media query to set the font size at different resolutions.

p {
  font-size: 16px;
}

/* 移动设备字体大小 */
@media (max-width: 480px) {
  p {
    font-size: 14px;
  }
}

.table-wrapper {
  overflow-x: auto;
}

.table {
  width: 100%;
}

.table th,
.table td {
  white-space: nowrap;
}
