Wow, that theme is pretty hostile with its styling!!! It has even written some HTML into the Connections search field code.

If the theme has a custom CSS area, add the following CSS to it:

body[data-form-style="minimal"] #cn-list .minimal-form-input {
    position: relative;
    padding-top: 0 !important;
    box-sizing: content-box;
    -webkit-box-sizing: content-box;
    -moz-box-sizing: content-box;
    display: inline-block;
    width: auto  !important;
}

input#cn-search-submit {
    background: url(http://bridge-alliance.com/wp-content/plugins/connections/assets/images/icons/search.png) 8px center no-repeat #FFF;
    border: 1px solid #DFDFDF;
    border-left-width: 0;
    -webkit-border-radius: 0 3px 3px 0 !important;
    border-radius: 0 3px 3px 0 !important;
    cursor: pointer;
    font-size: 12px;
    float: none !important;
    height: 28px;
    line-height: 20px;
    margin: 1px 1px 1px 0 !important;
    padding: 3px !important;
    text-align: left;
    vertical-align: bottom;
    width: 30px!important;
}

#cn-search-input {
    background: #FFF !important;
    border: 1px solid #DFDFDF !important;
    border-right-width: 0 !important;
    -webkit-border-radius: 3px 0 0 3px !important;
    border-radius: 3px 0 0 3px !important;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    color: #888;
    display: inline-block !important;
    font-size: 12px !important;
    float: none !important;
    height: 28px;
    line-height: 20px;
    margin: 1px 0 1px 1px!important;
    padding: 3px 6px !important;
    text-align: left;
    vertical-align: bottom;
    width: 140px !important;
}

#cn-search-input, input#cn-search-submit {
    box-shadow: inset 0 1px 1px rgba(0,0,0,.1) !important;
    -webkit-box-shadow: inset 0 1px 1px rgba(0,0,0,.1) !important;
}

#cn-list .chosen-container-single .chosen-search input[type=text] {
    color: #555;
    margin: 1px 0;
    padding: 4px 20px 4px 5px !important;
    width: 100%;
    height: auto;
    outline: 0;
    border: 1px solid #aaa !important;
    background: #fff url(http://bridge-alliance.com/wp-content/plugins/connections/vendor/chosen/chosen-sprite.png) no-repeat 100% -20px !important;
    background: url(http://bridge-alliance.com/wp-content/plugins/connections/vendor/chosen/chosen-sprite.png) no-repeat 100% -20px !important;
    font-size: 1em !important;
    font-family: sans-serif;
    line-height: normal;
    border-radius: 0;
}

This CSS should be sufficient to override the theme’s aggressive styling of forms.

Hope this helps, let me know.
