@philippe: Ok then you can replace the previous css with the following, in the following css I have added margin-right: 15px to make it space after the image.
.entry-summary .wp-post-image {
display: inline;
float: left;
margin-right: 15px;
width: 30%;
}
That color options are there in Catch Box Pro theme, there you can change the menu color from “Appearance => Theme Options => Color Options”.
In free theme, you need to work in manually by changing the color in the following css and add it in “Appearance => Theme Options => Custom CSS” box.
#branding #access {
background: none #585858;
}
