Summary  
This chapter explains CSS inline elements’ default display behavior and box model constraints, showing that their width and height can’t be explicitly set and only horizontal padding, margin, and border properties take effect.

General domain of usage  
Web page styling and layout.

**Inline elements** stay on a single line and wrap to the next line when space runs out. This behavior is controlled by the CSS property `display: inline`.

Key points about inline elements:
- They default to `display: inline`;
- Their width and height are determined by their content and cannot be explicitly set;
- Only horizontal properties like `padding`, `margin`, and `border` can be applied. 

Let's examine an example where some styles impact the element, while others do not, within the CSS file:

By default, **inline** elements have a gap on the right side; for `img` elements, this gap is at the bottom. This space is not attributed to `padding` or `margin`. Instead, it's an inherent blank space added by browsers to ensure a distance between each element.
