What do you mean the middle and lower segments are obviously occupied?

Occupying refers to temporarily occupying a space or position with objects, pictures, words, etc. So as to ensure that other elements can be arranged or arranged smoothly. Placeholders will be used in design, typesetting, photography and other fields to ensure the aesthetics and accuracy of the overall effect. For example, in web page making, you can use random pictures or fake words like Lorem ipsum to occupy space, so as to preview the overall layout, and then adjust and improve the unreasonable parts.

Placeholders are not only useful in design but also have many applications in real life. For example, in holiday decoration and celebration preparation, we often need to use some temporary decorations to occupy the venue or space. These things are usually designed for specific purposes, such as temporary stage and booth, temporary lanterns. They can add color to activities, and they can also facilitate activities if enough space is reserved.

Placeholders also have many practical functions in daily necessities. For example, in the cold storage, we can use beverage cans or bottles to occupy some blank areas, so as to make better use of the internal space, reduce energy consumption and maintain the freshness of food. Some daily necessities, such as furniture and bookshelves, will also be designed to contain lockers or occupy space, which is convenient for users to classify and store items. Although the design of these small spaces is inconspicuous, it can bring many conveniences to people's daily life.
