<a class="foo" alt="Hello World" href="/index.html">Hello World</a>
Go ahead and use the title attribute my friend!
<a href="#" title="hello universe!">Hello Everyone!</a>
What purpose do alt tags serve?
Search engines and other robots cannot interpret images, but images can play a crucial part in how people interpret a particular web page. Alt tags solve for this by providing text which is read by the search engines. When Googlebot or other search engine crawlers inspect a page, images with properly formatted alt text contribute to how the page is indexed and where it ranks.
Alt tags are also useful for users viewing a webpage on screen readers or browsers that can't process images.
Source: What is an alt tag, and how does it impact SEO?
But in your case you would like to use a href only for hyper link so use title tag only not alt tag.
<ul>
<li><a class="navbar" title="culture" href="../cultura/index.html">Cultura</a></li>
</ul>
If you're going to use img src then use alt tag it'll be more helpful.
Alt text is contained within the image tag example:
<img src="/demo/nike_air_zoom.png" alt="nike air zoom" title="nike air zoom" />
