In front-end development, we often need to display the text content returned by the interface, and it may contain a carriage return and line break. Usually we use v-html directives combined with regular expressions to replace the carriage return and line break labels. However, today I will share with you a more concise way to achieve the effect of carriage return and line break by using CSS styles, avoiding the complexity of using v-html.
