How to replace the system styles in elements?


from the example

<div class="col-md-4 col-md-push-7 phone-preview" style="margin:px;padding:60px;"> <div class="iphone-mockup"> <div class="screen"></div> </div> </div>

how do I change using Bootstrap Studio col-md-4 col-md-push-7 to col-md-4 col-md-push-9? The 'phone-preview' class is editable but now the 'col-md-4 col-md-push-7'.



Select that DIV that you want to change and the in the top right of the app in the Options pane, click on the Gear icon. Those there will be the settings for the col adjustments.
