Sometimes, you download a font or have a font that doesn’t have an italic style (see below).
In Adobe Indesign, there is a simple workaround for that.
Step 1: Make a new document, and make a text box and write.
Step 2: Highlight the text you want italic.
Step 3: Make sure you are in the text tool. In the skew box (false italic) increase the number to make the word italic and that’s it! I use the number 11
*Note: make sure the stroke color is the same as the text.
