"Side-by-side" refers to two or more things placed next to each other. This arrangement allows for easy comparison or interaction. For example, when you put two pictures next to each other, you can quickly see the differences and similarities between them. It’s a common way to display items, whether in art, design, or even in everyday life, like when friends sit together on a bench. In a broader sense, "side-by-side" can also describe collaboration or support. When people work side-by-side, they are cooperating to achieve a common goal. This teamwork can be seen in various settings, such as in a classroom where students help each other learn, or in a workplace where colleagues collaborate on projects.
