java - Overriding the default widget class names in gwt -

-

gwt uses standardized css class names such 

.gwt-image  .gwt-button

and on. prevents me using these classes popular css frameworks such bootstrap.

is there way can override these default style names , use bootstrap or foundation compliant class names ?

if using less css preprocessor, extend bootstrap mixins gwt classes

ex :

.gwt-button {     .btn(); //this bootstrap mixin buttons }

renders :

    .gwt-button{        display: inline-block;        margin-bottom: 0;        font-weight: normal;        text-align: center;        vertical-align: middle;        touch-action: manipulation;        cursor: pointer;        background-image: none;        border: 1px solid transparent;        white-space: nowrap;        padding: 6px 12px;        font-size: 14px;        line-height: 1.42857143;        border-radius: 4px;        -webkit-user-select: none;        -moz-user-select: none;        -ms-user-select: none;        user-select: none;     }

it's little time consuming, allows have in css
