42 | Chapter 3: Advanced Styling Handling Long Titles Suppose we had a page on our site with a title too long to fit in the header bar (Figure 3-4). We could just let the text break onto more than one line, but that would not be very attractive. Instead, we can update the #header h1 styles such that long text will be truncated with a trailing ellipsis (see Figure 3-5 and Example 3-7). This might be my favorite little-known CSS trick. Example 3-7. Adding an ellipsis to text that is too long for its container #header h1 { color: #222; font-size: 20px; font-weight: bold; margin: 0 auto; padding: 10px 0; text-align: center; text-shadow: 0px 1px 1px #fff; max-width: 160px; overflow: hidden; white-space: nowrap; text-overflow: ellipsis; } Figure 3-4.
