💎Set Font Size With Pixels
Setting the text size with pixels gives you full control over the text size:
📎Example:
-----------------------------
h1 {
font-size: 60px;
}
-----------------------------
💎Set Font Size With Em
To allow users to resize the text (in the browser menu), many developers use em instead of pixels.
1em is equal to the current font size. The default text size in browsers is 16px. So, the default size of 1em is 16px.
The size can be calculated from pixels to em using this formula: pixels/16=em
📎Example:
-----------------------------
h1 {
font-size: 3.5em;
}
-----------------------------
💎Set Font Size With REM
rem values are relative to the root html element, not to the parent element. That is, If font-size of the root element is 16px then 1 rem = 16px for all elements. If font-size is not explicitly defined in root element then 1rem will be equal to the default font-size provided by the browser (usually 16px).
When it comes to spacing and font-sizing, I prefer to use rem. Since rem uses root element’s font-size instead of its parent’s font-size.
📎Example:
-----------------------------
h1 {
font-size: 2.5rem;
}

CSS Opacity
💎The opacity property specifies the opacity/transparency of an element.
💎The opacity property can take a value from 0.0 - 1.0. The lower value, the more transparent.
📎Example:
-------------------------------
img {
opacity: 0.5;
}

Transparency using RGBA
💎If you do not want to apply opacity to child elements, Use RGBA
📎Example:
/* Green background with 30% opacity */
------------------------------
div {
background: rgba(76, 175, 80, 0.3) ;
}
