How do you hide text in HTML?

By placing text inside these parameters <!-- My Text --> it means the text will not show on a standard browser view. However, if you view the same page but in Source view then it will be viewable.

The idea of using this method is for 'commenting' in HTML code, and allows developers to add code to parts of their coding easier, or if you are designing a website/webpage for someone else, then they can see where their content should be placed. Basically, a placdeholder for code to be inserted.

It is not used to hide text inside HTML documents, since comments like this can be spidered and indexed by search engines. It's common practice to remove comment tags from any webpage for SEO purposes.

May be you can call a function in java script when the form is submitted, to check if that text field is empty. If it is empty, you can enter your default text and then submit the form from your javascript.

The comment tags you used are fine. Also you can do it in a paragraph:

<p>Only this <span style="visibility: hidden;">word</span> will not show.</p>
