Try adding to Home > Design > Custom Css to set the same width for three buttons:
#block-yui_3_17_2_1_1658339303941_1887 + .row .sqs-block-button-container a { min-width: 200px; }  

Setting color style for each button via the following code
#block-yui_3_17_2_1_1658339303941_3946 a { background: red; } #block-yui_3_17_2_1_1658339303941_5356 a { background: blue; } #block-yui_3_17_2_1_1658339303941_3003 a { background: green; } To get the right id for block you can use the following extension: Squarespace Id finder
