Style title slides with a header image differently

Since version 3.18.5, Slide Presenter supports title slides and title emojis on Confluence Cloud. The support works as follows:

• Title Emojis are simply added to the title text

• Header images are added to the slide as a fullscreen background.

It makes sense for your theme to provide a default title slide design if no header image is present. If you want to modify the styles for the title slide only if a header image is present, you can use the CSS class cover-picture:

/* Overwrite the margin properties of the title slide IF we have a cover picture */
.title-slide.cover-picture h1 {
    margin-left: 0;
    background: rgba(255,255,255,0.85);
    text-align: center;
}
