HTML Guide for css
The padding CSS shorthand property sets the padding area on all four sides of an element at once.
To specify no padding, use padding: 0 instead of padding: none.
Padding properties, unline margin properties, don’t accept negative values.
CSS styles could not be parsed, check the indicated line to find what caused the parser to fail. Common causes are unclosed curly brackets or comments, missing semicolons or unexpected or empty properties.
The text-overflow CSS property sets how hidden overflow content is signaled to users. It can be clipped, display an ellipsis, or display a custom string.
This property may be specified using one or two values. If one value is given, it specifies overflow behavior for the end of the line (the right end for left-to-right text, the left end for right-to-left text). If two values are given, the first specifies overflow behavior for the left end of the line, and the second specifies it for the right end of the line.
Here are some examples:
text-overflow: clip;
text-overflow: ellipsis ellipsis;
text-overflow: ellipsis " [..]";
/* Global values */
text-overflow: inherit;
text-overflow: initial;
text-overflow: revert;
text-overflow: revert-layer;
text-overflow: unset;
The text-transform CSS property specifies how to capitalize an element’s text. It can be used to make text appear in all-uppercase or all-lowercase, or with each word capitalized.
Examples of valid values for this property are:
text-transform: none;
text-transform: capitalize;
text-transform: uppercase;
text-transform: lowercase;
text-transform: full-width;
text-transform: full-size-kana;
The value break-word for the property word-break is deprecated, you should replace it with a valid value.
According to the CSS Text Module Level 3 spec:
For compatibility with legacy content, the word-break property also supports a deprecated break-word keyword. When specified, this has the same effect as word-break: normal and overflow-wrap: anywhere, regardless of the actual value of the overflow-wrap property.
The value specified for the transform CSS attribute is not valid.
The transform CSS property lets you rotate, scale, skew, or translate an element. It modifies the coordinate space of the CSS visual formatting model.

The ::file-selector-button has not been recognized by the W3C Validator. This seems to be a bug in the W3C Validator, which has already been reported.
The ::ng-deep CSS selector is often used in an Angular Component’s CSS to override the styles of a third-party component or a child component’s styles.
This CSS selector is now deprecated.
