When a page has some empty space, it is tempting to add something. A caption. Another image. A small detail that might tie everything together. Sometimes it helps to stop and see what happens if you do nothing.
Empty space gives things weight. A single sentence on a clean page reads differently from the same sentence surrounded by ten others. It has not become wiser or more precise. It simply has room to be heard.
A pause is part of the conversation
In music, silence is not a mistake. It separates one thought from another, changes the rhythm, and builds anticipation. A page can do something similar: give its visitor permission to take their time.
This does not make every empty screen a good one. Space works when there is a reason for it. Between a heading and a paragraph, it helps you shift gears. Around a piece of work, it makes details visible. At the end of a story, it lets the words linger.
Remove the last thing you added
Try a small exercise: finish a layout, then remove the last thing you added. Look at it again, preferably the next day. If nothing is missing, perhaps that element never needed to be there.
I like thinking of minimalism as a form of attention. You have to decide what deserves space and what can stay outside the page. That decision is usually harder than adding another section.
The next time you want to fill an empty corner, you could simply wait. Empty space has a job to do, too.
