Two lines of text on one line:

Is it possible to put two lines of text on one line?

I am doing some transcription work and where the original entry contains an error, is deleted and smaller correct text added above I'd like to show it like that.

At present I am using

[.herboyninetynine {
display:inline-block;
vertical-align:middle; /* Enables to rows to fit on one line */
font-size:.875em;
line-height:.875em;
margin:0;]

and then a to force the line break

but this makes the line space taller, and each line goes above/below the normal flow of word.
