I don't understand what you said. Show me the code of css.
My text is dynamic. It will change based on user action. It is not fixed. So the width is dynamic too. DDD888 发表于 3-10-2014 07:44

long story short， make that dame a element a fixed with and block element http://www.w3schools.com/cssref/pr_text_white-space.asp
nowrap咯，拿text的长度算不准的，你要知道字号什么的，思路是不要换行。 周星星1832 发表于 3-10-2014 08:33

If the text is long, will the element change width based on the text length? DDD888 发表于 3-10-2014 09:00

不能换行，我知道字号，我设置字号啦
我现在是随便假设字符宽度是18，但我想得到个通用的算法 this might help you.
