additional css

1) Make sure to check the option: Enable Addtional CSS

2) Clear cache after adding css codes.

Thanks ravis.
Have indeed enabled additional css and cleared cache and the theme is very selective in what it changes through the additional code

Worked:

legend {
font-weight: bold;
}

Doesnt work

.site-name a, .site-name a:hover {
color: #9d4d4d;
}

.site-name {
font-size: 2rem;
font-weight: bold;
text-transform: lowercase;
}

.header {
background-color: #b6a1b4;
}

#footer {
background: #8d602f url(/themes/tara/images/footer-bg.svg);
}

.sidebar-right {
background-color: #ef993a;
}

.image-field {
margin: 0rem 0rem 0rem 0rem;
}

.td {
padding: 10px;
}
