Is there any reason that relates to parsing time, layout, rendering time, style application, etc. to have HTML attributes in a certain (or consistent) order?
The order of HTML attributes does not improve a page's compressibility significantly, and maintaining some order can make the markup easier for human readers to figure out (e.g. putting id
first, starting <input>
s with type
, putting boolean attributes at the end of an opening tag) but I'd like to know if there are any performance reasons to consider attribute order.
The order of attributes in HTML elements doesn't matter at all. You can write the attributes in any order you like. but what sequence should be prefer, in practical?
Attributes go inside the opening HTML tag. The attribute name is a predefined name from the HTML specification. There are many: href , title , class , src , etc. The attribute value is that data for the attribute.
There are some attributes, such as id , title , class , style , etc. that you can use on the majority of HTML elements.
HTML attributes are generally classified as required attributes, optional attributes, standard attributes, and event attributes: Usually the required and optional attributes modify specific HTML elements. While the standard attributes can be applied to most HTML elements.
None to speak of I don't think. All the properties within each tag have to be parsed and read before the tag can be properly understood by the browser.
As long as the code is syntax-error free and (obviously) the shorter the better.
