In latex when I force a newline in a caption with \\ it gives an error saying \Hy@tempa has an extra } runaway argument?

Output

This is a common issue when using line breaks in captions with LaTeX. The problem occurs because the `\caption` command interacts with the hyperref package, which can cause issues with the `\\` line break. Here are a few solutions: 1. Use `\protect\\` instead of just `\\`: 

1
\caption{First line \protect\\ Second line}
2. Use `\newline` with protect: 
1
\caption{First line \protect\newline Second line}
3. Use a minipage environment: 
1
2
3
4
\caption{\begin{minipage}[t]{\linewidth}
First line \\
Second line
\end{minipage}}
4. If you're using multiple captions with line breaks, you can also define a new command in the preamble: 
1
\newcommand{\captionbreak}{\protect\\}
Then use it in your captions: 
1
\caption{First line \captionbreak Second line}
The first solution using `\protect\\` is usually the simplest and most straightforward approach.

Output

This is a common issue when using line breaks in captions with hyperref package. There are several ways to fix this: 1. The simplest solution is to use \protect before the line break: 

1
\caption{First line \protect\\ Second line}
2. Alternatively, you can use \newline instead: 
1
\caption{First line \newline Second line}
3. If you need multiple line breaks, you can also use a minipage: 
1
2
3
4
5
\caption{\begin{minipage}[t]{\linewidth}
First line \\
Second line \\
Third line
\end{minipage}}
The issue occurs because the hyperref package, which creates PDF bookmarks, can't handle certain commands in captions. Using \protect tells LaTeX to handle the command differently in the bookmark. The first solution using \protect\\ is usually the most straightforward approach.

Output

This is a common issue when using line breaks (\\\) in captions while the hyperref package is loaded. Here are two solutions: 1. Use \protect before the line break: 

1
\caption{First line \protect\\ Second line}
2. Use \newline instead: 
1
\caption{First line \newline Second line}
The first solution with \protect is generally recommended as it's more robust. The error occurs because the hyperref package processes caption text to create bookmarks/links, and the unprotected \\ command interferes with this processing. Example of complete usage:

Output

This is a common issue when using line breaks (\\\) in captions with hyperref package. Here are two solutions: 1. Use \protect before the line break: 

1
\caption{First line \protect\\ Second line}
2. Use \shortstack or \makecell: 
1
\caption{\shortstack{First line \\ Second line}}
or 
1
\caption{\makecell{First line \\ Second line}}
Note: For \makecell, you need to include the makecell package: 
1
\usepackage{makecell}
Both solutions should resolve the error while maintaining the line break in your caption.

Output

This is a common issue when using line breaks in captions with hyperref. To fix this, you can either: 1. Use `\protect\\` instead of just `\\`: 

1
\caption{First line \protect\\ Second line}
2. Or use the optional argument of caption to avoid the issue: 
1
\caption[Short caption]{First line \\ Second line}
The first solution with `\protect` is generally recommended as it explicitly protects the line break command from being expanded too early. The issue occurs because hyperref tries to process the caption text to create bookmarks/links, and the unprotected `\\` causes problems during this processing.
