Issues arising from script tags causing disturbances in CSS

As a newcomer to the world of web design, I recently embarked on a journey with Bootstrap and also started exploring the platform Codepen. However, after working on a project in Codepen and attempting to transfer my code to Sublime, some unexpected changes occurred. Suddenly, my footer became oversized and certain text turned gold, despite me not specifying such styles in my CSS.

I noticed that the placement of my CSS link and Bootstrap script within the HTML file seemed to impact how my page displayed. Even when I rearranged them, the desired outcome remained elusive. This left me pondering – why does the location of these elements matter if they are both housed in the head section?

Prior to encountering this issue, I had just installed Emmet and was beginning to experiment with Github by pushing files to the repository. While I'm unsure if these factors are connected to the current problem, they seem worth noting.

Answer №1

When it comes to applying CSS, there are specific rules that need to be followed:

  1. !important
  2. Rule origin
  3. Specificity
  4. Order

It seems like the issue you are facing relates to the 4th rule. This means that in a situation where you have the following CSS code:

.cssrule {
    color: white;
}
.cssrule {
    color: gold
}

The color will be gold because it was the last rule specified. To overcome this, the specificity rule is often used. For example:

#ida .cssrule {
    color: white;
}
.cssrule {
    color: gold
}

In this case, a div like the following:

<div class="cssrule" id="ida">

will apply the color white.
