Any HTML inserted into an HTML block must be valid HTML code. If your code isn't valid, then you may not have the option to save your code into the block.
Take a look below at an example of invalid HTML:
Notice how the first error says there isn't a start to the </tbody> tag. If you take a look at the highlighted </tbodyy> tag (shown in the screenshot above), you will see that there is a spelling mistake, the tag has an extra "y" letter before the end of it.
Here are some errors you may be seeing, and their cause.
|If you see this warning symbol:||The triangular ! symbol indicates that the HTML code you inputted should be revised for better validity. The red error notes at the bottom of the block may suggest what you should do to make your code valid. The save button will illuminate blue and allow saves with HTML warnings, unlike with HTML errors.|
|If you see this error symbol:||The squared X symbol indicates that the HTML code you inputted is not valid and should be reviewed in order to make it valid. The red error notes at the bottom of the block may suggest what you should do to make your code valid. The save button will not illuminate blue to allow saves with HTML errors in the block.|
