View on WordPress

With this plugin you can easily control your excerpt output and output of more tag. For example you can:
– Change excerpt tail to whatever you like (by default its ‘[…]’).
– Add link to current post and set the text of the link, for example: Read More, Continue Reading, etc.
– Change lenght of words in excerpt.
– Remove scroll from more tag.
– Change text for more tag link.
The advantage of this plugin is that it doesn’t use any external styles or scripts. You can style it whatever you want from your style.css file. Plus, it uses native wordpress php functions and filters, so it will not act badly on your site pagespeed.
Native WP Excerpt – is a handy, lightweight, clean code plugin that will be useful not only for simple blog and website owners, but also for theme developers.
