uniapp的app底部tabbar英文内容换行居中

To center the text in a tab bar item and allow it to wrap to a new line, you can add the following CSS to your UniApp project:

.tabbar-item-text {
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  text-align: center;
  white-space: normal;
}

This will apply a flexbox layout to the tab bar item text, centering it vertically and horizontally. `text-align: center` will center the text within its container, and `white-space: normal` will allow it to wrap to a new line if necessary.
