C# application small fix

Explanation how works the application : This application removes letters in several words to help user memorize texts. In order to help learning lessons, the program displays any text file sentence per sentence, and only shows start letters for a few words. The user must type remaining letters. Explanation of the task : Adapt the display so the string after a <LIST> tag and the one after the associated <ELSE> tag are in a vertical line, and have a specific color. For example (see screenshot), with the attached [login to view URL] opened with [login to view URL], the source text is the following: ... plusieurs corps <LIST> de contrôle <COOR> et <ELSE> d'inspection </LIST> antérieurs. the d in d'inspection should be in a vertical line with the d in de contrôle and in white, the text before (plusieurs corps) and after (antérieurs) being in green. The word et should thus appear left from the vertical alignement of the two d. BUDGET: 10$
