That would probably defeat the purpose of the alt attribute.
The required alt attribute specifies an alternate text for an image, if the image cannot be displayed.
The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).
I’m not sure how you can have a default tag that could describe every possible image.
Images that convey no information, but are purely decorative, can use an empty alt="" tag. That makes the page navigable for users of screen readers or non-graphical browsers.
It looks like the 1LD Feature Section stack only has an option for a background image and not a regular image. There is a difference in how images are used. Background images are applied with CSS and therefore do not have alt tags.
What’s not working? I don’t have the stack, but it should work, I just copied it, added an open <script> tag put it in an HTML stack and added an img stack with a class of feature-card and it added the alt tag.
These ALT attributes will not be seen by search engines indexing your website. And I imagine they’d be of very limited use to screen readers and other assistive tools. Ideally ALT attributes need to be hard-coded into the page.
As mentioned already, images that are provided purely for webpage cosmetics (like background wallpapers) do not require ALT attributes. You either leave the ALT attribute empty on an image or you set the image as a CSS background.
It’s only the images that form an integral part of your content (like images used to show products or promote services) that require the ALT attribute. Because in these situations, it is necessary to describe what the image is about; for the benefit of search engines, screen readers and other tools.
I don’t own the aforementioned card stack and cannot see a free demo for it. But I imagine if there is no ALT field in the settings, it was not intended to be used for content-critical images - only images to be used for decoration.
I try to give all images, even ones which are used as background images, informative names. I don’t know if that helps with SEO when there is no ALT attribute, but it can’t do any harm and it makes images easier to identify.
@instacks I am talking about search engines in the collective sense - grouping together Google, Bing, Yahoo, Baidu, DuckDuckGo, Yandex and all the others out there.
My advice to RapidWeaver users remains unchanged - ALT attributes for important images that need to be seen by search engines or broadcasted to assistive devices should have their ALT attributes hard-coded into the page. Then you are guaranteed everything and everyone will see them.
