The footer as the name suggest remains fixed in the bottom of the web page. For example, in the following page, we have a fixed footer in the bottom i.e. the footer remains even when the page is scrolled above − To create a footer that stays in the bottom and fixed, we will use CSS. Set the footer to stay at the bottom of a Web page using the position property Set the footer to stay at the bottom of a Web page using the position CSS property. The footer height, background color, and text color is set ... Read More
To affect other elements when one element is hovered, an element should be inside another element i.e. parent-child or sibling. On placing the mouse cursor on one element, the other’s property should change i.e. the hover affect is then visible. Change the color of another element when one element is hovered Example In this example, we will change the color of two boxes inside a div on mouse hover − DOCTYPE html> .parent { width: 500px; ...

The className property is used to change an element’s class. Here, we will see two examples − How to change the element’s class using className property. How to toggle between old and new classes. Change the element’s class using className property In this example, we will change the class of an element using the className property. Let’s say we have a div with class oldStyle − The div... We will set the above oldStyle class to a new class i.e. newStyle using the className property − function demoFunction() { ... Read More
The clearfix, as the name suggests, is used to clear floats. It is generally used in float layouts. The clearfix is considered a hack to clear floats. Overflow Issue Example Let us see the problem first before moving towards the solution. We have an image here, floated to the right. It overflows outside its container since it is way taller than the element belonging to it − DOCTYPE html> div { border: 2px solid blue; ... Read More
We can easily center text inside a div both horizontally and vertically. Let us see them one by one. Center Text in Div Horizontally using the text-align property To center text in div horizontally, use the text-align property. The text-align property determines the way in which line boxes are aligned within a block-level element. Here are the possible values − left − The left edge of each line box is aligned with the left edge of the block-level element's content area. right − The right edge of each line box is aligned with the right edge of the block-level ...

To remove extra space below the image inside div, we can use CSS. The following CSS properties can be used to get rid of the space − The vertical-align property The line-height property The display property Before moving further, let us see how the extra space below an image looks like − The image in a div can have an extra space below. It looks annoying and should be removed as shown below. We have marked the space as extra space below − Let us now see the fix − Clear the extra space below an image ... Read More
Normal trigonometric functions have analogous to hyperbolic functions, which are defined using the hyperbola rather than the circle. In hyperbolic geometry, hyperbolic functions are used to calculate angles and distances. Additionally, they appear in the answers to a lot of linear differential equations, cubic equations, etc. For given angle$\theta$. The hyperbolic sine function sinh$(\theta)$ is like below. $$\mathrm{sinh(x)\:=\:\frac{e^x\:-\:e^{-x}}{2}\:=\:\frac{e^{2x}-1}{2e^x}\:=\:\frac{1-e^{-2x}}{2e^-x}}$$ In this article, we shall discuss the techniques to get the value of sinh$(\theta)$ in C++ when the angle is given in the radian unit. The sinh() function To compute the sinh$(\theta)$ The sinh() function from the cmath package will be used. ... Read More
The right-angled triangle is the subject of the trigonometry concept known as the Tangent. The ratio between the angle's opposing leg and its adjacent leg when it is thought of as a right triangle is the trigonometric function for an acute angle. To calculate the tangent, we need to know the angle between the hypotenuse and the adjacent edge. Let the angle is 𝜃. The tan$(\theta𝜃)$ is like below: $$\mathrm{tan(\theta)\:=\:\frac{opposite}{adjacent}}$$ In this article, we shall discuss the techniques to get the value of tan$(\theta𝜃)$ in C++ when the angle is given in the radian unit. The tan() function To compute ... Read More
Cosine is a trigonometric term that deals with right-angled triangle. When an acute angle is thought of as being a member of a right triangle, the cosine trigonometric function measures the distance between the angle's neighbouring leg and the hypotenuse. We require the angle between the hypotenuse and the adjacent edge in order to calculate cosine. Let the angle is 𝜃. The cos$(\theta)$ is like below $$\mathrm{cos(\theta)\:=\:\frac{adjacent}{hypotenuse}}$$ In this article, we shall discuss the techniques to get the value of cos$(\theta)$ in C++ when the angle is given in the radian unit. The cos() function To compute the cos$(\theta)$ The ... Read More
Sine is a trigonometric parameter that deals with the right-angled triangle. The sine is the ratio of the opposite side to the hypotenuse. While calculating sine, we need the angle between the hypotenuse and the opposite side. Let the angle is 𝜃. The sin(𝜃) is like below − $$\mathrm{sin(\theta)\:=\:\frac{opposite}{hypotenuse}}$$ In this article, we shall discuss the techniques to get the value of sin(𝜃) in C++ when the angle is given in the radian unit. The sin() function To compute the sin(𝜃) we need to use the sin() method from the cmath library. This function takes the angle in radian and ... Read More
