Style Guide for optimum class arrangement in Bootstrap framework

I've come across various Style Guides that discuss declaration and attribute ordering, but surprisingly none that specifically address class ordering.

For instance, one developer's code looks like this:

<div class="btn btn-primary btn-lg mt-2 ml-3">My button</div>

While another developer's code is written like this:

<div class="mt-2 ml-3 btn btn-lg btn-primary">My button</div>

I am seeking consistency in class ordering. Are there any established Style Guides or best practices that focus on this particular aspect?

Answer №1

There isn't a definitive guide on class ordering as the sequence of classes on an element doesn't affect specificity. They simply refer to the corresponding CSS rules and are subject to cascading effects in the stylesheet.

Consider a scenario where a HTML block has conflicting classes, one for displaying and one for hiding the element.

<div class="show hide">
  <p>Some content</p>
</div>

.show { display: block; }
.hide { display: none; }

Now, let's swap the classes and observe the outcome.

<div class="hide show">
  <p>Some content</p>
</div>

.show { display: block; }
.hide { display: none; }

Both instances will ultimately hide the content due to the cascading nature of CSS.

It's advisable to follow a consistent approach that aligns with your understanding.

Answer №2

The positioning of your button will determine the classes you need to include. To start, make sure you include the following classes:

btn btn-lg btn-primary

These classes will ensure that your button takes up space within the specified div. Next, add classes that will customize the button properties:

mt-2 ml-3
