This may seem to defeat the purpose of a code block, but I\'d like to be able to bold something within a code block. For example, if I wanted to bold the return line:
You would have to do this in HTML, by design.
However, inside Markdown code spans and blocks, angle brackets and ampersands are always encoded automatically.
<pre>
int main(void) {
<b>return 0;</b>
}
</pre>
This syntax should solve your problem :
``` int main(void) { **return 0;** } ```
Just type three backticks in the beginning of the code block and it's should work.
