This is the feature that changes how you work more than any filter or brush: the moment a design stops being a picture and becomes a form that fills itself in.
Select a text or image layer, open Properties and pick a variable under Dynamic content. The sources are broad: the post title, excerpt, content, category and date, the author name and bio, the site name and tagline, WooCommerce product fields including price, sale price and discount, every ACF text or image field, and any custom field at all by its meta key.
Two things make it survive contact with real content. Text layers take a minimum and maximum font size, so a long title shrinks until it fits and anything still overflowing is shortened rather than escaping the frame. And bound image layers have an image fit setting with an anchor, so featured images of any shape land cropped rather than squashed.
The detail I like most: a variable with no value hides its layer. Bind a discount badge to the discount field and it appears only on products that are actually on sale. No conditional logic, nothing to maintain, and one template quietly becomes several.
While designing, View then Preview with Post drops real content into the design so you can see what a genuinely long headline does before you commit. It is non-destructive, your placeholder text comes back when you leave, and it is the fastest way to find out whether a template is robust.
