(Highlight the plug-in code of emlog. Using emlog blueleaf to simplify the code highlighting plug-in can make the front code display box look better. After using the plug-in, make sure that the template file footer PHP has a loading point <? php doAction('index_footer'); ?> Code, if not, please add it yourself. Finally, when publishing articles in the background, the editor toolbar uses the function of inserting program code. You can see the effect of emlog blueleaf simplifying code and highlighting plug-in on the article page. It has the same effect as the figure below.)
