I have found an example of responsive email templates where there are such CSS selectors such as the following:
a[class="btn"] Why is this syntax used if it's totally the same as:
a.btn Does it have any impact on mobile browsers or anything else?

The CSS Attribute Selector is used to select an element with some specific attribute or attribute value. It is an excellent way to style the HTML elements by grouping them based on some specific attributes and the attribute selector will select those elements with similar attributes.
CSS [attribute|="value"] Selector The [attribute|="value"] selector is used to select elements with the specified attribute, whose value can be exactly the specified value, or the specified value followed by a hyphen (-).
Presence and value selectorsMatches elements with an attr attribute whose value is exactly value, or contains value in its (space separated) list of values. Matches elements with an attr attribute whose value is exactly value or begins with value immediately followed by a hyphen.
In CSS, class and ID selectors are used to identify various HTML elements. The main benefit of setting class or ID is that you can present the same HTML element differently, depending on its class or ID.
The [] syntax is an attribute selector.
a[class="btn"] This will select any <a> tag with class="btn". However, it will not select <a> which has class="btn btn_red", for example (whereas a.btn would). It only exactly matches that attribute.
