Click in the paragraph section to pull up the settings box. 

This is a basic 2 column layout for "Post" content type.

Now with the settings box pulled up, highlight the line of text and select bold. 

In the right hand tool bar with your text still selected, choose a font size. 

Using the settings box, click the highlighted icon, which selects the right side column. 

Click the "Width" field in the right hand tool bar. 

Type "70" to equal "70%". Currently, the two columns are "50%" each. 

Now selected the image and then the same icon for the left side column. 

In the "Width" section of the right hand tool bar, change "PX" to "%".

Now we will add a background color. Select the right side column once again. 

In the right hand tool bar, expand "Color".

Select a color for "Background color". I chose Golden Yellow.
