‼️🌹 CSS SYNTAX 🌹‼️
🌹CSS Selector🌹
A CSS selector selects the HTML element(s) you want to style.
CSS selectors are used to "find" (or select) the HTML elements you want to style.
We can divide CSS selectors into five categories:
➡️ Simple selectors (select elements based on name, id, class).
➡️ Combinator selectors (select elements based on a specific relationship between them).
➡️ Pseudo-class selectors (select elements based on a certain state).
➡️ Pseudo-elements selectors (select and style a part of an element).
➡️ Attribute selectors (select elements based on an attribute or attribute value).
We shall be learning the most basic CSS selectors.
1️⃣ The CSS Element Selector
The Element Selector selects HTML elements based on the element name.
Example
The CSS rule below will affect the HTML p element on the page:
p {
text-align: center;
color: red;
}
2️⃣ The CSS id Selector
The id selector uses the id attribute of an HTML element to select a specific element.
The id of an element is unique within a page, so the id selector is used to select one unique element!
To select an element with a specific id, write a hash ( #) character, followed by the id of the element.
Example
The CSS rule below will be applied to the HTML element with id="para1":
{
text-align: center;
color: red;
}
3️⃣ The CSS class Selector
The class selector selects HTML elements with a specific class attribute.
To select elements with a specific class, write a period (.) character, followed by the class name.
Example
In this example all HTML elements with class="center" will be red and center-aligned:
center {
text-align: center;
color: red;
}
You can also specify that only specific HTML elements should be affected by a class.
Example
In this example only elements with class="center" will be red and center-aligned:
p.center {
text-align: center;
color: red;
}
HTML elements can also refer to more than one class.
