For example, let's say I have a logo. The name of the company in large font. Below that the company tagline in smaller font , but I want them to both be the same exact width. Ideally I'd like to be able to play with the font size of the tagline and the spacing of the letters to get it to the width of the company name. Hopefully I am making sense here. I see at the end of the tagline this little box that i can pull out to the width i want, but when i do so, nothing happens and it just snaps back to where it was. What is the purpose then of this little width-adjusting box? It doesn't seem to actually do anything at all??
