One of these features is that this chair usually has a long back that it helps the gamers to keep their back in a good situation and save them from back ache.

The Importance of gaming Chairs:  
Gaming chairs may seem unfamiliar to the general public, but they are becoming an essential accessory for game fans . Characteristics of gaming chairs differ them from other types of chair. Gamers usually sit on the game chair for a long time. A professional gamer may sit in a chair for about 10 hours a day. Therefore, having a comfortable and standard chair in which the principles of ergonomics are well observed; it's too important. The chair should be adjustable so that the person can easily sit in a comfortable position relative to his computer.Characteristics of gaming chairs allow the gamer to fully enjoy the game.A chair has certain parts, each of which must have characteristics in order to be accepted as a good chair.

Comparing a play chair with an office chair:
a gaming chair , the back of the chair is long and extends to the head. In addition, the back and seat of the chair are serrated and keep the body firm and stable. There is no holding position in a normal chair and it can be said that it is difficult to sit properly on it for a long time.Another difference between game chairs and office chairs is in their design and color. Game seat designers try to use colorful designs to make these seats look like a sports car. This chair may be pink or bright red. Of course, these chairs have a good variety of colors and game enthusiasts can easily match it with their play space. While in other chairs, designs usually do not fall out of the category of public furniture.Also, in game chairs, unlike ordinary chairs, a more durable metal frame is used so that heavy users can use it for a long time without worry. In general, these chairs are wider than ordinary chairs.
In the following articles, the expected features of each part of the seat suitable for the game will be stated.

Seat back: 
One of the characteristics of gaming chairs is the long back of it. Seat back is of particular importance. Because it can help keep the back in a straight and upright position and prevent back pain.The back of the chair should be at a suitable height that can support your pelvis, spine and back well. Also, its slope should be adjustable. Having lumbar cushions and head cushions are useful for optimizing the backrest and helping to sit better. Leaning the head back makes the weight of the head split on the neck, making it easier to look at the monitor while lying down.

Chair bases: 
Chair bases play a very important role in the quality of the chair. In addition to maintaining the balance of the chair, they are also effective in positioning the person's legs. In some models of gaming chairs, the bases are designed in such a way that they place the legs in a higher position and create a relaxed state for the person. These chairs are ideal for playing video games in front of the TV and when playing with the computer.

Seat handles:
The importance of chair handles is due to the fact that in case of any defect in the chair handle, it may cause the feeling of pain in the wrist, arm or elbow area.The difference between the handles of a gaming chair and an office chair is in their movability. In a gaming chair, the handle of the chair is movable and it can be moved in different directions. The ideal chair handle should be such that the person can place his arms in parallel or on the table after sitting on the chair. It should also help keep the elbows close to the body and form a right angle. The wrist should also be as aligned with the elbow as possible. The height of the arm of the chair should be easily adjustable. In the best possible case, the arm of the chair should have a three-dimensional position and the height, depth and width of the arm should be easily adjusted.Another important point about the arm of the seat is the presence of suitable cushions on it so that it provides comfort to the gamer's hands.

Chair seat: 
It is one of the most important parts of the chair that can be examined from different perspectives. First of all, the size of the chair should be large enough for the person to sit comfortably in. The ideal size is such that after sitting down and placing your feet on the ground, there is as much space as four fingers between the knees.The seat of the chair should be soft enough so that it does not cause any problems for the person after sitting for a long time. Also, very good sponges should be used in this part so that it does not lose its shape by bearing the weight of the gamer for a long time and has good durability.

Price of game chairs:
Gaming chairs are expensive due to their special capabilities. In some models, features such as a masغیر مجاز می باشدer have been added, the price has increased. But do not worry, there are also student game chairs and game chairs with more limited features that are less expensive.

Game chair material:
One of the most important things when buying a game chair is to pay attention to its material. As mentioned in the previous sections, the playing chair is usually used for long hours. Therefore, it is important that the material is such that it minimizes sweating and is easy to clean.The materials used in the game chairs can be divided into two groups: fabric and synthetic leather. In fabric samples, air conditioning is better and they have good durability; but in this group, the seat is more likely to get dirty and stains are usually visible. Synthetic leathers have a special beauty and are resistant to stains because they repel water. In leather game chairs, the air does not flow well and it is not very easy to use them in hot seasons such as summer.

Seat angle: 
There are many models of gaming chairs that have a "lying down function" that allows you to relax a little by changing the angle of your backrest. The longer the lying angle, the easier you can relax. One of the best positions for professional gamers is the perfectly flat mode, which supports up to 180 degrees. You can adjust the angle so that the seat is parallel to the ground, so you can lie down while playing or downloading a game . Or you can even take a nap in your spare time before starting an in-game event.

Network security has 3 types, physical network security, technical network security and administrative network security, in fact, this layer is very widespread and can ultimately help maintain system security.

- Vulnerability programs:
In this layer, all the weaknesses of a system are examined, because hackers are constantly trying to find security holes in a system, to be able to access the information of different people.

- Strong access control measures:
This layer of security also has 3 types, Discretionary Access Control (DAC), Managed Access Control (MAC) and Role-Based Access Control (RBAC), as the name of this layer implies, all the actions that are being done in this layer are aimed at controlling people's access to information.

By learning CSS, you can avoid the repetitive use of HTML code, which can save your time a lot and also keeps your work organized, which is of a great importance, and with the introduction of different programming languages ​​and also the importance of being updated regularly, site designers can spend more energy to design different sites with more features and ultimately be able to provide better results as well as facilities to their users, so in this article we will mention some tips on how to build links, lists and tables using CSS, but first we are going to define CSS.

What is CSS?
It stands for Cascading Style Sheets is a language which was created to shape and make a website as well as web pages and its internal components, and it is one of the main tools for web designers, along with HTML, JavaScript, etc., which is being used a lot.

How to create links in CSS?
Links are very important in the content of a site, and it is necessary to increase your knowledge about linking and related topics,

existing links can be designed in different ways depending on their states, which in the following we will discuss more about this, in general the four links states are:

- a: link:
One of the types of links that we need to mention is this type which includes all links that are normal and unvisited.

- a: visited:
This is another type of link that, as the name implies, includes links that different users have visited.

- a: hover:
In this type, the users hit the link with their mouse, but they do not click on it.

- a: active:
It refers to the exact time when the user clicks on the link.

It should be noted that if you wanted to use multiple link modes in CSS at the same time, a: visited must be followed by a: link or a: active must be followed by a : link, a: visited and a: hover.

For example:

/ * unvisited link * /
a: link {
color: red;
}

/ * visited link * /
a: visited {
color: green;
}

/ * mouse over link * /
a: hover {
color: hotpink;
}

/ * selected link * /
a: active {
color: blue;
}

Text Decoration:
Links can more beautiful by removing the lines below them which gives a beautiful and appropriate look to the content, if you want the explanation of the 4 states that a link can have which we have explained each of them earlier, you need to do the following.

a: link {
text-decoration: none;
}

a: visited {
text-decoration: none;
}

a: hover {
text-decoration: underline;
}

a: active {
text-decoration: underline;
}

Background Color:
Another thing that can be changed in relation to the links and caused a link to be displayed in a way that we want, is its background color, which in order to change this, as in the previous case, you can write simple code, and you can do this in a way that the users can realize that the link currently exists in which of these 4 positions.

a: link {
background-color: yellow;
}

a: visited {
background-color: red;
}

a: hover {
background-color: green;
}

a: active {
background-color: blue;
}

There are some examples of coding for links which have been mentioned above, each of which is for a separate feature for the link, but imagine that you want to determine multiple features such as color, background color, no line below the link, and so on, in order to do this, you must do the following.

a: link, a: visited {
background-color: # 0000ff;
color: Blue;
padding: 13px 26px;
text-align: center;
text-decoration: none;
display: inline-block;
}

a: hover, a: active {
background-color: yellow;
}

Another example:
a: link, a: visited {
background-color: green;
color: blue;
border: 2px solid green;
padding: 8px 16px;
text-align: center;
text-decoration: none;
display: inline-block;
}

a: hover, a: active {
background-color: red;
color: white;
}

How to create lists in CSS?
Lists can be very helpful to a user who has come to your site, and you want to see, a complete list of all your products, or a list of product prices and thousands of other lists, each of which may be used for an application, there are generally two main types of listings in CSS, which are as follows.

II. Strawberry cake

III. Vanilla Cake

List-style-type:
One of the features that can be changed in these lists according to your decision is that you can choose what to use next to the items in your list, for example in Unordered Lists, someone may select items that the members of the list should be shown with a square and so on, which we have given you an example in this regard below.

ul.a {
list-style-type: circle;
}

ul.b {
list-style-type: square;
}

ol.c {
list-style-type: upper-novel;
}

ol.d {
list-style-type: lower-alpha;
}

List-style-image:
Another feature that these lists can have is that they use different images to show the items in the list, in which case the following command can be used to achieve this goal.

ul {
list-style-image: url ('smiley.gif');
}
ol {
list-style-image: url ('sqpurple.gif');
}

List-style-position:
This will help you determine where you want each of the markers on your list to be, the position of them may be as follows.

- outside:
In this case, the markers in the list are in a position outside the existing list frame.

-  inside:
In this case, the markers that are placed next to each of the list items are inside the list frame.

ul.a {
list-style-position: inside;
}

ul.b {
list-style-position: outside;
}

List-style-type: none:
By default, there are a number of features for this type of list that you may not want, you need to modify them with the help of the following code.

ul {
list-style-type: none;
margin: 0;
padding: 0;
}

List-style Shorthand property:
If you want to specify all the attributes that a list can have which you can specify them in relation to a list, you need to do the following.

ol {
list-style: circle outside url ("sqpurple.gif");
}

Create color lists:
As you know, the ultimate goal of all this work is to attract more users, so you can make the existing lists colorful, so that you can attract more users to your content, it should be noted that if you do not want the whole list to be colored uniformly, you can use the

tag, in which case each item in the list will be colored separately.for example:

for example:
ul li {
background: # ffe5e5;
margin: 5px;
}

How to create tables in CSS?
It is possible for you to use it to create an attractive look for the tables in your content, which we will explain in more detail below, it should be noted that there are two elements in tables, and .

border: 1px solid blue;
}

Full-Width Table:

table {
width: 100%;
}

Last word:

How to embed audio files?
With the help of HTML5 you can do this task easily, but it should be noted that it is necessary to specify the source, and you also need to embed the control feature in it, so that the user who is using that audio can play or pause it, audio formats may be Ogg, mp3, wav, and so on, which are not specified in the HTML5 draft, but these three audio formats are supported in HTML.

The

There are various browsers such as Chrome, Firefox, Safari, Opera, etc., all of which support all three audio formats mentioned above, except for Safari, which does not support OGG format, but it supports two other audio formats.

These audio files have features such as autoplay, autobuffer, controls, loop, muted, preload, src, which we will briefly explain about each of them in the following.

Autoplay:
As you know, this feature detects that the sound should be played as soon as it is ready.

browser does not support the audio element

Autobuffer:
If the file does not be played automatically, the autobuffer will be started automatically by installing this feature.

How to embed a video?
By adding videos to various contents, especially educational content, users can gain a positive user experience and ultimately make the best use of the web , and it should be noted that video has more features than audios, due to the fact that Video is visual unlike audio, which is the reason why it has more features such as poster, length and width in addition to audio file ones.

Users may try to visit the site through various devices and then view the video, so HTML5 can be considered as a great help to site owners, so that users with any device can get a positive user experience from using the site, we will briefly explain each of the features in the following.

Length and width:
The size of the videos is very important, and you can use CSS to control this size, a feature that all of them must maintain properly is the ratio between length and width which is called the aspect ratio, and this is very important.

Poster:
This feature shows an image before the video is played, which its attractiveness is of a great importance, due to the fact that different users may be attracted to the video and click on it after seeing the attractive poster, so it is necessary to choose a good image as the poster for your work.

Video files also come in a variety of formats, including mpeg4 and Ogg, the most important feature of image files like audio files, is the source, which is necessary to be properly specified in the tag, and browsers try to use the first format they identify, by seeing the source.

Adding an image file may be done as follows:

 - HTML5 player libraries:
These players are implemented with JavaScript, in fact, they make more compatibility between different browsers, so that they can provide the user with video which contains more features and better quality, for example, one of the features that can be supported which may not be supported in some browsers is a subtitle that can cause the user to have a very positive user experience by watching the video, in addition to the points which have been mentioned above, JavaScript can provide many features that browsers may or may not support, all of which can significantly improve the quality of video.

Important note:
As mentioned before, all browsers may not support all audio and video formats, so you should use the following trick to give this opportunity to the users who visit your site with any browser and play the video or audio file, to be able to achieve their goal and meet their needs as well, for example, in the case of audio files that as you know they have two formats, you can use the following trick.

<"audio controls =" controls

Your browser does not support the audio element

In this example, we have provided the source tag twice in both available formats, so that the browser shows the file which is able to play, and when neither MPEG nor OGG can be supported by the browser, a text will be displayed to the user including the sentence that your browser does not support the audio element.
