You will reinforce your practical understanding of the new standard with demo applications and tutorials, so that execution is one short step away. Padding is an amount of space around a content and its edge. With other words, padding is a white space or a clear area around a text or an image. It generates the white space inside of the element's edges. The padding comprises padding-top , padding-right , padding-bottom and padding-left properties. In such a way you get complete power over the padding.
The thing is that the padding values can be set up in px, pt, cm, em , etc. The thing is that such relative units perform great on different screen sizes and browsers. However, negative values are false. The padding property can point out one, two, three, or four values. In case you need a boxed element with all four sides equal, set one value which will apply to all sides. If two values are used, the first will apply to [top-and-bottom] , and the second will set to [left-and-right] values.
Three values define first to [top] , then to [left-and-right] and third to [bottom]. If you set each side using unique four values , it will start applying clockwise to [top], [right, bottom ] and [left ]. Use shortcuts to make your coding simpler. When the value is set as a percentage, it is relevant to the [width] of an element. Keep in mind, the total breadth of the element corresponds to the width property plus the width of any padding area. In light of this, the width is recalculated each time the padding is adjusted.
Unlike margin, any padding can have a background color or image. The color of the padding area is defined via a [background] property. In case the element has a background color, the padding will inherit that color.
Thus, if you need your background color to continue on into the space you design, the background will continue on behind the padding. Image resolution is the number of detail an image holds. The term applies to raster digital images. Higher resolution means more image detail.
A raster image is an image consisting of the array of pixels. A pixel is the basic element of the two-dimensional digital image. At the same time, a pixel is also the physical element of the display matrix.
In the raster format images are displayed on the most of the image output devices: monitors, printers, cell phones, etc. The width and height of the image in pixels are the image size. And the number of pixels per inch PPI is the resolution of the image. The higher is the resolution, the more pixels are located in one inch. And the smaller a single one will be.
Thus, the more precise will be the details of the image. High definition images are a consequence of a greater resolution. Resolution determines the clarity of the objects and text on the monitor. At high resolution objects on the screen become smaller and look sharper. Monitors usually have standard 4: 3 or widescreen 9 and dimensions.
This is the screen ratio. The number of pixels horizontally and vertically is the screen size. In printing the resolution is measured in DPI, dots per inch. For the photo to be of a normal quality, a resolution must be at least dpi.
For example, to print a photo on the A4 piece of paper xmm or 8x11 inches, we need to multiply 8 by and 11 by And get xpx. This should be the minimum size of the picture for printing on A4 sheet. If the size will be smaller, the printed image will be fuzzy and blurry. RGB color model stands for Red, Green and Blue is an additive color model in which those three main colors are mixed together to create other colors.
RGB color system is suited for surfaces that produce their own light. The screen surface of a computer monitor or a TV set is originally dark, so its original color is black. All other colors are obtained by using a combination of the three main colors, which in their mixture must create a white color.
Experimentally it was proven that red, green and blue are the most suited for human eyes. As we know, the surface of the screen is not solid, it consists of small dots called pixels. Each pixel consists of three blocks, red, green and blue. By varying the brightness level of each block we can get different colors. The information about the brightness level is encoded using binary code. For example, the most common for modern displays bit True Color system uses three bytes with values from 0 to for each pixel on the screen.
Absolutely red color will have a value This means that the amount of red color is full, of the green is 0 and of the blue is also 0. Absolutely blue color will have a value of 0. With different combinations different colors are formed: bright-violet is RGB color can also be encoded with the help of the hexadecimal system.
Here are some standard colors:. This color system is called additive. In other words, we take black color no color and add primary colors to it, mixing them all the way up to white.
This way we can encode 16 colors, which is more than enough for human eyes. In a word, alt tag is an abbreviation of what is essentially an alt attribute on an image tag showing a nature or a content of its image. That is why each image on any successful website has its alt tag that describes what is actually on it.
As a result, various screen readers will make the image from your website accessible while reading out this alternative text. To illustrate the situation, that is an example of a complete HTML image tag:. So, why does one need alt text for their images? As it has already been mentioned, the alt text literally tells what an image depicts as well as describes the main function of this image on the web page.
Generally speaking, you just propose a person to use some services or buy some products that you provide with the help of this button. Thus, its alternative text simply explains what the button is used for. As you can see, there is nothing complicated. Here is another simple example of using alt text.
As you can see from the screenshot below, this blue call-to-action button lets a person get a shown website template right now. What is more, talking about the image buttons, you could also put some extra call to action text to it.
Actually, it is quite popular policy, so I am sure that you have seen such things a plenty of times while surfing through the web space. Below you can see the next example of this function.
Keep in mind that every image you want to use for your online project should have its own alternative text. In point of fact, visually impaired and blind visitors of your site will also use alt in order to figure out what an image or a button is for.
What else should you know about it? Ok, now you know a lot of information about the pluses of alternative text. Still, I know what you are thinking about right now: what should you do in case your image does not have a clear purpose?
