    HTML 5 tooltip not showing in Firefox when using required attribute in form input


    I have tried the following:


    <input name="Depot" id="Depot" type="text" class="form-control 
    attach-validation" aria-required="true" required="required"/>
    it works in chrome but in Firefox I am not seeing the tooltip stating the field is required.

    any help here is much appreciated

    My form is being loaded via Ajax, I'm not sure if that would be a problem?!

    There is no tooltip stating that a field is required in Firefox. You only know that it is required if you try to submit a form without filling the field.

    ... AND how they are handled varies from browser to browser since what things look like or are implemented is none of HTML's business, nor should it be.

    Though you can in modern browsers FAKE IT. If you put an empty element after (yes, empty, this s*** has no business in the HTML as plaintext) like a span, you can target it via "input:required + span" for any style you like. I would use generated content to create the message if it were demanded by a client... But only after telling the client we shouldn't be dicking around with that.

    In fact there are many pseudo-states you can exploit with CSS on inputs now. :required, ptional, :valid, and :invalid are all useful states.

    also, this is 2019 not 2009, you can drop the XML nonsense of required="required" or the silly trailing slash. Likewise I'd lose the ARIA role BS as it adds NOTHING of value to the page, particularly something as silly and pointless as aria-required.

    I also find your excess of classes... disturbing.

    <input type="text" name="Depot" required>

    ... and be done with it. You only need the ID if your LABEL has a for attribute. You can avoid both by wrapping the label around the input if the formatting would allow for it.

    But yeah, the default appearance of a required input is not specified by HTML and varies from browser to browser. I have no clue what you mean by a "HTML 5 tooltip" as there's no such thing!
