The general style phase is really important. Once you have set the style of these html elements the rest of your design process (especially when you need to make changes afterwards) will go much faster.
For example: let's say the client wants to have a change made to the tile border on the website and you have 5 different tile components installed from the upgrade store. If you used the general style to design the tiles you will only need to update it once. If you styled each tile individually you will need to do this process 5 times.
Open the layout you created or edited in the previous phase in the design editor. To set the general style make sure placeholder view is selected. This is the default view when opening a layout in the design editor. In a later phase we are going to style content pages as well.
To open the main style panel for general styling click the green painbrush icon on top right of the side panel or click the green button next to website style.
In placeholder view all generalstyle elementsarerenderedin thecontentsection of the page. You can also click on the green icon next each of these elements individually to open it's style panels instantly.
There are two groups defined: general settings and site elements. When you click the green button you will see the entire list of elements you can style.
The style panels work in the same way as the design elements and page components (which comes later). You browse through the many properties and change whatever you want. You will instantly see the preview page update. Click the green save button to generate a new css file with the updated values.
You can always skip this step in this phase if you prefer to add the content to your website first. But just remember to come back to general styling before you start designing your content elements individually.
