There are many ways. Tables, for example are responsive by default. Use no width or percentage based widths. You can also use Flexbox or Grid. However, the question I think you are asking is “how can I make it the same everywhere?” The answer there is you can’t, and shouldn’t. See this

If you replace the underline with some other display properties, please ensure that you use more than one and that they are clearly differentiated from surrounding text. Then, test.
