What sets apart styling with div elements versus styling directly on input elements?

Looking at the code provided, we can see that both the div and input element have classes applied to them - "fields" and "input-fields." This raises the question: why do we need both classes? Wouldn't it make more sense to just choose one to style the input field?

Here is the code snippet:

.fields {
  display: inline-block;
  text-align: left;
  width: 48%;
  vertical-align: middle;
}

.input-fields {
  height: 20px;
  width: 280px;
  padding: 5px;
  margin: 10px;
  border: 1px solid #c0c0c0;
  border-radius: 4px;
}
<div class="fields">
  <input type="text" id="name" class="input-fields" placeholder="Enter your name" required>
</div>

Answer №1

It's important to note the distinction in this scenario. The div element serves as a parent to the input element, with some properties from the div being inherited by the input. However, properties of the input do not transfer back to the div; the impact is solely on the input itself. For instance:

/* Example 1: div has background color while input does not */
/* Properties set for the first div affect the input (padding and text-align) */
.firstDiv {
  height: 100px;
  background-color: lightblue;
  text-align: center;
  padding: 30px;
}

/* Example 2: input has background color while div does not */
/* Copying all properties from firstDiv to see the impact on secondInput */
.secondInput{
  height: 100px;
  background-color: lightblue;
  text-align: center;
  padding: 30px;
}
<div class="firstDiv"><input type="text" class="firstInput" placeholder="I am first input"></div>
<div class="secondDiv"><input type="text" class="secondInput" placeholder="I am second input"></div>

Both the input and div elements share the same css properties. In the first case, these properties apply to the div, while in the second case, they apply to the input. This comparison showcases how each element can have identical effects despite operating on different tags with varying inheritance.

Answer №2

A common misconception is that the fields class applies to all elements within it, but in reality, it only affects the div element directly. Any properties specified within the fields tag will not carry over to child elements, except for some attributes that may be inherited.

For example, if you set a background: black; property in the fields class, only the background of the div itself would turn black and not any other elements inside it.
