What distinctions can be made between the id selector and class selector when implementing border styles?

When trying to set the border width to 0px, I noticed that the border style doesn't seem to work when using a class selector. Oddly enough, the border width does work if an id selector is used!

Below is the HTML (Vue template) code:

<el-form-item label="Title">
    <el-input type="text" id="title" name="title" placeholder="title" v-model="editForm.title"></el-input>
</el-form-item>
<el-form-item label="Tags">
    <el-input type="text" class="edit-input" v-model="editForm.tags"></el-input>
</el-form-item>

Here is the corresponding CSS:

.edit-input, #title {
    box-shadow: 0 2px 12px 0 rgba(0, 0, 0, 0.1);
    border: 0;
    margin-bottom: 10px;
}

Resulting output:

I'm puzzled by this issue. Why doesn't the border work with a class selector? Is there something wrong in my code?

Answer №1

One common issue in CSS styling is the concept of CSS specificity, which determines which styles take precedence over others.

If you're facing conflicts with your CSS, it's essential to understand CSS specificity. A simple breakdown of CSS specificity can be summarized as follows:

  • Element selectors like div have a weight of 1
  • Class selectors such as .edit-input carry a weight of 10
  • ID selectors like #title are the most specific with a weight of 100

IDs, being highly specific selectors, should be used sparingly in CSS to avoid difficulty in overriding their styles in subsequent rules.


If conflicting styles are present on your page, due to more specific selectors, the less specific ones will not apply. For example:

div .edit-input { /* selector "weight": 11 */
  border: 1px solid #DFE1E7;
}

In this case, a rule like this might not work because of its lower specificity:

.edit-input { /* selector "weight": 10 */
  border: 0;
}

To override conflicting styles, make sure to use a selector with equal or higher specificity. For instance:

.el-input .edit-input { /* selector "weight": 20 */
  border: 0;
}


For resolving CSS conflicts effectively, inspect the element using your browser's developer tools to understand the existing styles and create your CSS with adequate specificity for successful override.
