css font exceeds omission

In web development, text content often exceeds the scope of the container, which not only affects the beauty of the page, but also reduces the user's reading experience. In response to this situation, CSS provides a solution to achieve the effect of fonts beyond omission.

1. Basic principles of CSS excess ellipsis

Font excess ellipsis means that when the text content in an element exceeds the space allocated by the element, the excess part is marked with an ellipsis (.. .) means that in order to better display the text content, CSS text overflow is realized through the following three attributes:

• text-overflow: used to control how the text after it exceeds the width of the element is displayed. ;
• white-space: used to control line breaks and spaces in the text;
• overflow: used to control how the overflow content of the element is displayed.

Among them, the text-overflow attribute contains the following values:

• clip: the default attribute value, the excess content will be hidden;
• ellipsis: Exceeding content displays ellipses (...).

2. Specific implementation method of CSS font exceeding omission

1. Single line text exceeding omission

For single line text, we can use the following methods To achieve the effect of font exceeding ellipsis:

.overflow-text { white-space: nowrap; /* 禁止换行 */ text-overflow: ellipsis; /* 超出省略 */ overflow: hidden; /* 溢出隐藏 */ }

With the above code, we can hide the text content that exceeds the width of the container and replace it with ellipses.

2. Multi-line text exceeds the omission

For multi-line text, the text content needs to be wrapped first, and then the beyond-omission operation is performed. The specific implementation code is as follows:

.overflow-text { display: -webkit-box; -webkit-box-orient: vertical; -webkit-line-clamp: 3; /* 控制显示行数 */ overflow: hidden; /* 溢出隐藏 */ text-overflow: ellipsis; /* 超出省略 */ }

Among them, -webkit-box-orient is used to select the direction of text wrapping, -webkit-line-clamp is used to control the number of lines of text display, and finally the content that exceeds the width of the container is Hide and replace with ellipses.

3. CSS font overflow omission compatibility issue

It should be noted that the text-overflow attribute may not be recognized in some browsers, so it needs to be prefixed for compatibility processing .

.overflow-text { white-space: nowrap; overflow: hidden; /* 兼容WebKit内核浏览器 */ text-overflow: -webkit-ellipsis; /* 兼容非WebKit内核浏览器 */ text-overflow: ellipsis; }

4. Summary

Through the above method, we can easily achieve the omission effect of text beyond the scope of the container, and make the page more beautiful and easy to read. In actual development, we need to adjust specific values to achieve the best results, and consider compatibility issues to ensure correct display in various browsers.
