Is [there] another method that DOESN’T exclude the activated button in a serialization? There is not, the behavior is based on the submit event of the <form>, not of a button, e.g. hitting enter or calling .submit() in JavaScript. You’re mixing 2 concepts here, a .serialize() or .serializeArray() may or may not have anything to … Read more
The CSS Grid spec developers decided to use identifiers instead of strings, when defining named grid areas with the grid-area property, for the sake of consistency with the rest of CSS. The vast majority of CSS properties use identifiers, not strings, for their values. (Notable exceptions to this rule include font-family, content and grid-template-areas, which … Read more
The general meaning of “margin” isn’t to convey “move this over by 10px” but rather, “there must be 10px of empty space beside this element.” I’ve always found this is easiest to conceptualize with paragraphs. If you just gave paragraphs margin-top: 10px and had no margins on any other elements, a series of paragraphs would … Read more
Transferring my comment to an answer, because it makes logical sense. However, please note that this is unfounded conjecture. The actual reasoning of why the spec is written this way is still, technically, unknown. Element height is defined by the height of the children. If an element has padding-top: 10% (relative to parent height), that … Read more
http://www.w3.org/TR/html4/interact/forms.html#h-17.5 Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to “image”, but the BUTTON element … Read more

If you have special characters in your URL, you should use quotes or escape the characters (see below). Syntax and basic data types The format of a URI value is ‘url(‘ … Read more
From the CSS 2.1 Spec: When an inline box contains an in-flow block-level box, the inline box (and its inline ancestors within the same line box) are broken around the block-level box (and any block-level siblings that are consecutive or separated only by collapsible whitespace and/or out-of-flow elements), splitting the inline box into two boxes … Read more
Here is a good article from the MDC which explains the problems (and solutions) to form autocompletion. Microsoft has published something similar here, as well. To be honest, if this is something important to your users, ‘breaking’ standards in this way seems appropriate. For example, Amazon uses the ‘autocomplete’ attribute quite a bit, and it … Read more
It is claimed in the book that an inline element has complete padding properties but no margin-top/button properties, only margin-left/right properties. My first question is, where can I find this as an official statement? You won’t, because it isn’t quite true. In the box model it says that for margin-top and margin-bottom: These properties have … Read more
