Let's talk about the most easily ignored CSS mandatory line breaks_html/css_WEB-ITnose

Generally, elements have the default white-space:normal (automatic line wrapping, PS: no line wrapping is white-space:nowrap). When the entered text exceeds the defined width, it will automatically wrap. But when the entered data is a bunch of characters or letters or numbers without spaces (regular data should not be there, but some testers will do it this way), when the width of the container is exceeded, the container will be expanded. Line break.
Solution (use IE, chrome, FF as test browsers):

Java code

1. {
3. word-break:break-all; /*Supports IE, chrome, FF does not support*/
5. word-wrap:break-word; /*Support IE, chrome, FF*/
7. }

The following is a description of the difference between the two methods:
1, word-break:break-all For example, if the div width is 200px, its content will automatically wrap to 200px. If there is a long English word at the end of the line (congratulation, etc.), it will truncate the word into this The end of the line is conra (the front-end part of congratulation), and the next line is the back-end part of tulation (conguatulation).
2. The word-wrap:break-word example is the same as above, but the difference is that it will congratulate the entire word as a whole. If the end of the line is not wide enough to display the entire word, it will automatically put the entire word down. One line without truncating the words.
3, word-break;break-all Supported version: IE5 or above This behavior is the same as normal in Asian languages. Breaks within any word of a line of non-Asian language text are also allowed. This value is suitable for Asian text that contains some non-Asian text.
Word-wrap:break-word Supported version: IE5.5 or above The content will wrap within the boundary. If necessary, word-break will also occur. The table automatically wraps to avoid stretching.
Syntax: word-break: normal | break-all | keep-all
Parameters: normal: In accordance with the text rules of Asian and non-Asian languages, line breaks are allowed within words
　break-all: This behavior Same as normal for Asian languages. Breaks within any word of a line of non-Asian language text are also allowed. This value is suitable for Asian text that contains some non-Asian text
Keep-all : Same as normal for all non-Asian languages. For Chinese, Korean, and Japanese, word breaks are not allowed. Suitable for non-Asian text that contains a small amount of Asian text
Syntax: word-wrap: normal | break-word
Parameters: normal: Allow content to push against the specified container boundary
Break-word: Content will be within the boundary Line break. If necessary, word-break also occurs. Description: Sets or retrieves whether to break the line when the current line exceeds the boundary of the specified container.
Suggestion: 3C detection of word-break will show problems, which will also cause problems in Baidu snapshots - this attribute OPERA FIREFOX browser does not support the word-break attribute. You can use white-space:normal; instead, so that in Line breaks can be done correctly under both FireFox and IE, and please note that spaces between words cannot be used to replace them, otherwise line breaks cannot be done correctly.
