With CSS, you can add a small arrow to a tooltip using the ::after pseudo-element. The arrow is created by combining the content property with CSS borders to form a triangular pointer that connects the tooltip to its trigger element. Syntax .tooltip::after { content: ""; position: absolute; border-style: solid; border-color: tooltip-color transparent transparent transparent; } Example: Tooltip with Top Arrow The following example creates a tooltip that appears above the trigger element with a downward-pointing arrow − ...

To set the navigation bar at the bottom of the web page, use the position: fixed property combined with bottom: 0. This creates a sticky navigation bar that remains visible at the bottom of the viewport even when the user scrolls through the page content. Syntax nav { position: fixed; bottom: 0; width: 100%; } Example The following example demonstrates how to create a fixed bottom navigation bar − ul { ... Read More
A priority queue is a special type of queue where elements are served based on their priority rather than the order of insertion. In C, we can implement a priority queue using a linked list where each node contains data, priority, and a pointer to the next node. In a priority queue, elements with higher priority (lower numerical value) are processed first. If two elements have the same priority, they follow FIFO order. Syntax typedef struct node { int data; int priority; struct node* ... Read More
To set the navigation bar at the top of the web page, use the position: fixed property combined with top: 0. This creates a fixed navigation bar that remains visible at the top even when users scroll down the page. Syntax .navbar { position: fixed; top: 0; width: 100%; } Example The following example creates a horizontal navigation menu that stays fixed at the top of the page − body { ... Read More
We are given with the n number of processes i.e. P1, P2, P3, ..., Pn and their corresponding burst times. The task is to find the average waiting time and average turnaround time using FCFS CPU Scheduling algorithm. What is Waiting Time and Turnaround Time? Turnaround Time is the time interval between the submission of a process and its completion. Turnaround Time = completion of a process − submission of a process Waiting Time is the difference between turnaround time and burst time Waiting Time = turnaround time − burst time What is FCFS Scheduling? ...

The CSS position: sticky property creates elements that behave as relatively positioned until they reach a specified scroll position, then become fixed. This is particularly useful for creating navigation bars that stick to the viewport when scrolling. Syntax selector { position: sticky; top: value; } Key Properties PropertyDescription position: stickyMakes the element sticky when scrolling topDistance from top of viewport where element becomes fixed z-indexStacking order (optional) Example: Sticky Navigation Bar The following example creates a navigation bar that sticks to the ...

In CSS, you can create a tooltip with an arrow pointing to the bottom by using the ::after pseudo-element to generate a triangular shape. This is achieved by manipulating border properties to create the arrow effect. Syntax .tooltip .tooltip-text::after { content: ""; position: absolute; top: 100%; left: 50%; margin-left: -border-width; border-width: size; border-style: solid; border-color: tooltip-color transparent transparent transparent; } Example The ...

In optics, the focal length is a fundamental property of lenses that determines their converging or diverging power. Given the image distance and object distance from a lens, we can calculate the focal length using the lens equation. What is Focal Length? Focal length of an optical system is the distance between the center of lens or curved mirror and its focus. It represents the distance over which initially collimated rays are brought to a focus. ... Read More
Link dividers in navigation bars help separate menu items visually, making the navigation cleaner and more readable. You can add dividers using CSS border properties. Syntax li { border-right: width style color; } Example: Vertical Dividers with Border-Right The following example uses the border-right property to add vertical dividers between navigation items − ul { list-style-type: none; margin: 0; ...

Here we will see programs that return different results when compiled with C or C++ compilers. These differences arise due to fundamental variations in how C and C++ handle certain language features. Character Literal Size Differences In C, character literals like 'a' are treated as int type, while in C++ they are treated as char type. This affects the result of the sizeof() operator − Example 1: C Code #include int main() { printf("Character: %c, Size: %d bytes", 'a', sizeof('a')); return 0; } ... Read More
