1. I don’t understand what do you mean by use the option “more”. If you are talking about more button in your post. That that is used for splitting content for archive pages. Read more about it at http://devotepress.com/wordpress-writing-editing/how-to-split-content-using-the-more-tag-option/. So, if you have blog and set it up as “Show Full Content” from “Appearance => Customize => Theme Options => Layout Options => Archive Content Layout”. This this breaks the text when you add that more tags. But it’s not useful when you are using expert layout.
2. We don’t recommending changing font as it’s responsive design and it changes as per the screensize. But if you want to change it, then you can change the font size in the following css and add it in “Appearance => Theme Options => Custom CSS Options” box. It will change font for
@media screen and (min-width: 991px) {
/* Default Font Sizes */
body, button, input, select, textarea {
font-size: 15px;
}
/* Title Font Sizes */
.entry-title,
#promotion-message h2,
#featured-content #featured-heading {
font-size: 30px;
}
/* Sidebar Widget Title Font Sizes */
.sidebar .entry-title, .widget-title {
font-size: 20px;
}
}
3. Yes, you can insert picture in widget. You can drag and drop “CT: Advertisement” widget to your sidebar from “Appearance => Widgets” and then add your image URL in “Image Url” box.
