Selecting elements by tag, class, and ID in CSS

Selecting elements by tag, class, and ID in CSS 

    CSS provides different ways to select and apply styles to HTML elements. The most common ways to select elements in CSS are by tag, class, and ID. Understanding how to select and apply styles to elements is essential for creating visually appealing web pages. In this blog, we will discuss how to select elements by tag, class, and ID in CSS with examples.

Selecting Elements by Tag:

    To select elements by tag, simply reference the tag name in the CSS selector. For example, to apply styles to all h1 elements in your HTML document, use the following CSS code:

h1  {

  font-size: 36px;

  color: #333; 

  font-weight: bold;

}

    This will apply the specified font size, color, and font weight to all h1 elements in your HTML document.

Selecting Elements by Class:

    Classes provide a way to group elements that share the same styling. To apply styles to elements by class, add a class attribute to the HTML elements and reference it in your CSS code using the "." selector. For example, let's say we want to apply a background color to all elements with the class "highlight."

We can use the following CSS code:

.highlight  {

  background-color: yellow;

}

    This will apply a yellow background color to all elements that have the "highlight" class in your HTML document.

Selecting Elements by ID:

    IDs are used to uniquely identify elements in an HTML document. To apply styles to an element by ID, add an "id" attribute to the HTML element and reference it in your CSS code using the "#" selector. For example, if we want to apply a different background color to a specific element with the ID "main-header,"

we can use the following CSS code:

#main-header  {

  background-color: blue;

}

    This will apply a blue background color to the element with the "main-header" ID in your HTML document.

Conclusion:

    In conclusion, selecting elements by tag, class, and ID are fundamental skills in CSS. By using these selectors, developers can apply styles to specific elements or groups of elements in an HTML document, providing more control over the appearance of the web page. It's essential to keep in mind that the specificity of the selector affects the priority of the applied styles. Selectors that are more specific will override less specific selectors, so it's important to use them appropriately. By mastering the art of selecting elements in CSS, developers can create beautifully styled web pages that are visually appealing and easy to navigate.
