I just can ignore this property and I will get the same result, right?

If so, what is the meaning of using text-decoration: none; as a declaration in CSS.

This is my first question.

I'm trying to understand CSS and it's declaration's properties.

If the element you are applying the CSS to has no default text-decoration, then yes there is no immediate functional benefit to applying that CSS rule.

However, consider you are using the <a> HTML element (or anchor element). This has the default CSS style:

text-decoration: underline;

You may want to remove this underline (for whatever reason). This is a scenario when you could use the style rule a {text-decoration: none;}, to remove the underline.

CSS libraries like Bootstrap may also apply unwanted CSS rules that you wish to remove, or maybe you are already applying a CSS rule to an element, but want to remove that styling in specific cases.

You might also apply CSS rules of this nature as a preventative measure, to mitigate the risk of future CSS changes applying rules where you may not want them to.

In short, you use CSS rules like text-decoration: none; to remove existing CSS rules.

The MDN web docs is a great source to learn about CSS, and the other fundamental technologies of the web, If you want to learn more. Here is a link to their page on the text-decoration CSS rule.

Hope this helps.

One example of things affected by the none would be <a>/href=””links, that to most browsers, become blue once turned into links. using text-decoration: none; shows the browser that it should not add anything extra to the text, thus keeping it consistent with the other type on your page.
