• The text color of alert-warning and alert-danger is not matching the colors in figma.
• Could you check the text size of the text in button-sm and compare it to the text size in the figma? Also the text size of the buttons in the deploy & run module - the Deploy & At Address seem smaller than the buttons for the function names of a deployed contract .

There is a typo in the font-size:
.btn-sm, .btn-group-sm > .btn { padding: 0.25rem 0.5rem; font-size: 11pxs; line-height: 1.5; border-radius: 0.2rem;}
