The commented code lines would wrap long company names to a second line. That can be implemented as soon as someone figures out how to either dynamically update the .sidebar margin or statically set it to margin: calc(6rem +1px).

Hi @ColDog5044 thank you for the pull request, however this can be accomplished with text-center class thats built into bootstrap 4 / adminlte 3.
