| 17 | <h1>Handling of "!important" property flag</h1>
|
|---|
| 18 | <p>
|
|---|
| 19 | Normally later css style properties defined later are overriding earlier ones.<br>
|
|---|
| 20 | Except if they are marked with the flag "!important".<br>
|
|---|
| 21 | Those can only be overridden by style properties which are also marked "!important".
|
|---|
| 22 | </p>
|
|---|
| 23 |
|
|---|
| 24 | <p>There are two classes of property overriding</p>
|
|---|
| 25 | <ul>
|
|---|
| 26 | <li>inherit (nested html tags)</li>
|
|---|
| 27 | <li>merging (more css properties to the same html tag)</li>
|
|---|
| 28 | </ul>
|
|---|
| 29 | <p>This is handled similarly for all styles, so we check only examples here</p>
|
|---|
