Right now, the HubSpot icon library doesn't have the updated X logo (formerly Twitter). But no worries, we've got a great icon setup in Act3, so replacing the logo in the header and footer should be easy.
From the Icon module, select the Code option, and then paste one of the SVG codes provided below – whichever one you prefer.
For this icon :
