Mastering CSS: Stylesheets, Syntax, and Visual Enhancements
CSS Essentials
Why Use CSS?
- Greater control over typography and layout
- Separates style from structure
- Allows styles to be stored externally, making documents smaller and easier to maintain
Types of CSS
- Inline Styles: Written within HTML tags
- Embedded Styles: Added within
<style>tags in the<head> - External Styles: Stored in separate
.cssfiles, linked to HTML - Imported Styles: Styles from one CSS file imported into another
CSS Syntax
- Rule Structure: Each rule has a selector and a declaration
- Example:

Find the Longest Common Prefix
#include <iostream>
#include <vector>
#include <string>
using namespace std;
string longestCommonPrefix(vector<string>& strs) {
if (strs.empty()) return "";
string prefix = strs[0];
for (int i = 1; i < strs.size(); i++) {
int j = 0;
while (j < strs[i].length() && j < prefix.length() && strs[i][j] == prefix[j]) {
j++;
}
prefix = prefix.substr(0, j);

1. Single vs. Broadcast Streams
Single Subscription Streams
- Allow only one listener at a time.
- Ideal for sequential data processing (e.g., file reading, API calls).
- Example: File I/O, HTTP requests.
Broadcast Streams
- Allow multiple listeners simultaneously.
- Best for real-time data/event broadcasting (e.g., WebSocket updates, UI events).
- Example: Button clicks, live data updates.
Code Example
import 'dart:async';
