I connected the label with the dataset on a blog quote, how to keep the label from being cut off
What you are doing with a text button is not a code related issue, therefore you should be going through Wix Support for more help with this issue.

To fix it you have two choices.
Make the button bigger to accommodate the text;
Make the font size smaller so that it all fits into the required size button.
Or setup the Wix Blog’s recent posts feature and you will be able to click on the post and go straight to the blog post itself.

For a code option, use the trending posts or recent posts tutorials.
