1. To add logo to your site, you can go to “Appearance => Header”. Then if you want your header image to be with site title and tagline, then you can add the following css in “Appearance => Theme Options => Custom CSS” box:
#site-logo, #hgroup.with-logo {
display: inline-block;
float: left;;
}
2. For menu curved top left and bottom right, you can add the following css in “Appearance => Theme Options => Custom CSS” box:
#branding #access, #colophon #access-footer {
-moz-border-radius: 10px 0;
-webkit-border-radius: 10px 0;
border-radius: 10px 0;
}
3. To change the background color of the main area, then you can change the color code in the following css and then add it in “Appearance => Theme Options => Custom CSS” box:
#main { background-color: #eee; }
4. All the changes that you have mage it through theme options panel and your pages, posts, category and all will be remain unchanged when you update the theme. But if you have mode modification to core theme files like style.css, functions.php, index.php and so on or add/edit any files inside ‘catch-box’ folder, then these edits will be gone when you update. As update restores all original files and folder inside ‘catch-box’ folder.
