To handle long words that cause overflow issues in your design, you can apply CSS styles to control the overflow of text within the elements. You can use the CSS property word-wrap and set it to break-word. This will allow long words to break and wrap onto the next line instead of overflowing the container. Additionally, you can use the overflow property to add scrolling if needed.

word-wrap: break-word;
text-overflow: ellipsis;
overflow: hidden;
