I would like to use the alt attribute so I can use it for my search widget in WordPress.
I am using elementor and WordPress editor so I can add the attributes with HTML.
<h3 alt="seawater">seawater</h3>
I tried this code and went to my search widget but the results weren't what I expected.
I know I can use YOAST plugin so maybe I should dig into that instead.
I would like to do an SEO for the paragraphs that are important on the website.
The "alt" attribute is used as an alternative information for an image if for some reason that image can't be loaded or if the user is using a screen reader.
For img tags, "alt" attribute is required.
You can also use it with area and input tags.
Regarding your question about SEO and Heading Tags, I think you should take a look at best practices about it. How and When to use them really matters if you're worried about SEO.
You can use alt only for <area>, <img> and <input> tags.

I understand that for a website to be "accessible", images should in general have the alt tag. The alt tag should provide alternate text for the image, in particular when the image contains content that is relevant for the user.
When one uses the alt tag like :<img alt= "alttext" ...> the alttext does not display when the mouse hovers over the image. If one adds the title tag, then one can have the alttext displayed.
My question is: Is the use of the title tag appropriate for this?
I have found a bit of conflicting information on this:
This site seems to discourage the use.
This site seems to say that the use is fine.
alt attribute is displayed when the image cannot be loaded, and used for accesibility when that feature is set in the browser. It also helps for Search Engine Positioning (SEO) (thanks #Chris for noting this)
alt HTML reference
title is just Advisory information and it's disadvantaged for accesibility purposes. Source: W3.org
title HTML reference
For example, this is an extension for chrome (offered by google) that show alt text, not title..
If your aim is to have some text appear when you hover over an image, then yes, the title attribute is appropriate. Ensure that any key information in the title text is duplicated elsewhere on the page.
If your aim is to provide additional information about the image to all your readers, then you will need to consider an alternative way for keyboard and touch based users to read that content. It may be simpler just to display the content next to the image for all users.
Unless your image is focusable, relying on a tooltip is not a solution.
Having to use the mouse to discover the subject of an image is not accessible to keyboard only users.
What you need to do is :
providing an alt text for screenreader users (people who can't see it)
provide contextual description next to the image if you need to give all of your visitors more elements (like copyright owner, artwork title, ...).
Note that you have to set an alt text, it still can be empty if the alternative is not relevant (decorative images, or redundant information).
If I have a link (anchor) in the header that just contains an image, like this:
<a href="index.html" title="Home">
<img src="http://placehold.it/200x50" alt="Site Name">
</a>
Is this accessible? The alt attribute appears to be overridden by the title attribute. I know that title is not usually necessary, but because nothing is describing the link except the alt text (which only has the Site Name because the image is a site logo in this case), the title is supposed to say that the link goes back home. I can't add any text because I don't want to hide it with CSS; that would not fit with progressive enhancement.
Where should the link description go in this case? Alt or title? What's the best practice?
Titles of surrounding links don't override alts on images. Both will be announced by screenreader software unless the user has chosen to suppress titles in the settings (if you've ever listened to a Wordpress site you'll understand how too many can be annoying).
Best practice is to leave out the title and rely on the alt as the link content for cases where the image is not seen or not loaded. You can see an example here: http://www.w3.org/TR/2014/NOTE-WCAG20-TECHS-20140408/H30 in the techniques for 2.4.4 Link purpose (in context).
Visually-hidden text can work well with progressive enhancement. It shouldn't be used as a catch-all for poorly designed widgets, but it can help provide context for non-sighted users. I use it more for indicating the current page in a menu when there are no graphics but just colours, that sort of thing.
There is nothing unaccessible about the way you have it. You provided both a description of the link and the image. As for what goes where, the link description should go in the title while the image description should go in the alt. titles aren't as common or necessary, but alts are important for both SEO and accessibility (screen readers and in case the image doesn't load).
I'm looking for a cross browser solution to display information when "hovering" on an element, I know this can be done with JS dynamically but I'd prefer in this specific case a basic static HTML solution.
According to mozilla developers website (here) using title instead of alt is the best practice but I'd like more "field experience" to help me decide if I should go for ALT, TITLE attr or JavaScript
Thank you very much
Title attribute is for tooltips and is supported by all major browser. You should use it.
Alt attribute isn't about tooltips at all.
When defining a title or alt to an anchor tag, which is valid HTML5?
Is it best to define both, or only one?
Does it affect SEO at all?
in HTML, even from version 4, the title attribute is valid for almost all elements. alt is different in that it's only valid for images, the idea being to provide a text only alternative version of the image, which would be useful to people with visual impairment (as they'd be able to hear their browser read the text)
It's good practice to provide an alt attribute for images, even if you're going to leave an empty string ( "" ). The alt attribute helps improve accessibility for screen readers since the user most likely can't see the image with which it's associated. The title is less useful for accessibility purposes but is still a good practice to get into.
Sometimes, we have to do multi-lingual content in e-newsletter.
Is is good to use local language on the alt tag?
or just plain English.
One important purpose of the alt attribute on the img element is allow screen readers (used by visually impaired people) and other "non-visual" software to know what the image represents. If you want to localize your HTML page you should also localize the contents of the alt attribute.
If you could not use an image and had to express the information using text (keeping in mind that text around the image is still there and duplicating content isn't useful) — what language would you use?
That is the language you should use for alt text.
It depends on your page content. Use the same language in alt tag what you are using for your page content. Obviously you don't want Arabic language to show-up when image is missing; if your default page language is English.
Hope it answers your question.
I can only assure you that you should use translated texts in attributes. Not just alt, but title for example.
If you use English texts there, this should be considered hard-coded string. That is just because that kind of strings are visible to user - even if image is available, contents of these attribute are visible in a tooltip when you place mouse over the image (or in the status bar, depending on web browser).
