Why does the button stretch past the content width without specifying any width properties?

The buttons stretch their content width to fit the .col div.

However when the align-self: flex-start; rule is applied to .button the button shrinks the size of the content width to the length of the text. 

@media screen and (min-width: 769px) {

        .main-header,
        .main-nav,
        .row,
        .col {
            display: flex;
        }

    .main-header {
    flex-direction: column;
    align-items: center;
    }

    .col {
        flex: 1;
        flex-direction: column;
    }
    .button {
        margin-top: auto;
        align-self: flex-start;
    }
}

The default value of align-self is auto, which causes the item to stretch to fill the available space.

For more details, see the MDN page on align-self.
