## كيفية إنشاء صندوق الضوء
 | 
						|
 | 
						|
### المقدمة
 | 
						|
 | 
						|
والصندوق المبسط هو مزيج من عنصرين ، أحدهما [مشروط](https://en.wikipedia.org/wiki/Modal_window) وعرض شرائح. هنا سوف تقوم ببناء صندوق خفيف بسيط باستخدام `HTML` و `CSS` و `JavaScript` .
 | 
						|
 | 
						|
سيتم تضمين صندوق الضوء في الوسائط ، التي سيتم تشغيلها بواسطة بعض `JavaScript` ، من [معالجات الأحداث](https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Event_handlers) في ترميز `HTML` . ستقوم ببناء الأنماط التي ستوفر حالة مع `CSS` والسلوك مع `JavaScript` . ستجد أيضًا قائمة مرجعية بالطرق التي تستخدمها وغيرها من وحدات tid المفيدة ذات الصلة بهذا البرنامج التعليمي ، في الجزء السفلي.
 | 
						|
 | 
						|
#### صورنا
 | 
						|
 | 
						|
يتم توفير الصور التي [سنستخدمها](https://www.pexels.com/) بواسطة [Pexels](https://www.pexels.com/) ، معرض صور المخزون المجاني الذي يسمح لك بتوفير صور عالية الجودة لمشاريعهم بسرعة ، ومجانًا ، وعادة بدون الحاجة إلى استخدامات.
 | 
						|
 | 
						|
#### فقط أرني الكود!
 | 
						|
 | 
						|
يمكن العثور على مثال حي [هنا - CodePen / Lightbox](https://codepen.io/rdev-rocks/pen/KXNzvo) ومسودة كاملة للرمز بالقرب من القاع.
 | 
						|
 | 
						|
### الخطوة 1. الترميز
 | 
						|
 | 
						|
يوفر الترميز أو `HTML` ، بنية العلبة الخفيفة.

### الخطوة 2. نمط مع CSS
 | 
						|
 | 
						|
يوفر لك `CSS` حالات مختلفة لصندوق الضوء الخاص بك. أشياء مثل الرؤية ، وتحديد المواقع ، وتأثيرات التمرير.
 | 
						|
 | 
						|
يجب أن تبدو ورقة الأنماط الخاصة بك كما يلي:
 | 
						|
 | 
						|
 `/* Here you provide a best practice's "reset", read more about it at the bottom! :) */ 
 | 
						|
 
 | 
						|
 html { 
 | 
						|
  box-sizing: border-box; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 *, *:before, *:after { 
 | 
						|
  box-sizing: inherit; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 body { 
 | 
						|
  margin: 0; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 /* You define the style of our previews here, you are using flex to display the images 
 | 
						|
   "responsively". */ 
 | 
						|
 
 | 
						|
 .preview { 
 | 
						|
  width: 100%; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 .row { 
 | 
						|
  display: flex; 
 | 
						|
  flex-direction: row; 
 | 
						|
  justify-content: space-between; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 .row > .col { 
 | 
						|
  padding: 0 8px; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 .col { 
 | 
						|
  float: left; 
 | 
						|
  width: 25%; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 /* Now you want to define what the lightbox will look like. Note that you have the display 
 | 
						|
   as none. You don't want it to show until the user clicks on one of the previews. 
 | 
						|
   You will change this display property with JavaScript below. */ 
 | 
						|
 
 | 
						|

 | 
						|
   one is shown at a time. */

  flex-direction: row;

  justify-content: space-between;

						|
 } 
 | 
						|
 
 | 
						|
 /* You want the previews a little transparent to show that they are "inactive". 
 | 
						|
   You then add an .active or :hover class to animate the selections for your user when 
 | 
						|
   they interact with your controls and clickable content.

 |

 } 
 | 
						|
` 
 | 
						|
 | 
						|
### الخطوة 3. جافا سكريبت
 | 
						|
 | 
						|
الآن للعمل! يجب أن تبدو جافا سكريبت مثل هذا:
 | 
						|
 | 
						|
 `// Initialize here and run showSlide() to give your lightbox a default state. 
 | 
						|
 
 | 
						|
 let slideIndex = 1; 
 | 
						|
 showSlide(slideIndex); 
 | 
						|
 
 | 
						|
 // You are providing the functionality for your clickable content, which is 
 | 
						|
 // your previews, dots, controls and the close button. 
 | 
						|
 
 | 
						|
 function openLightbox() { 
 | 
						|
  document.getElementById('Lightbox').style.display = 'block'; 
 | 
						|
 } 
 | 
						|
 
 | 
						|
 function closeLightbox() { 
 | 
						|
  document.getElementById('Lightbox').style.display = 'none'; 
 | 
						|
 }; 
 | 
						|
 
 | 
						|
 // Note that you are assigning new values here to our slidIndex. 
 | 
						|
 
 | 
						|
 function changeSlide(n) { 
 | 
						|
  showSlide(slideIndex += n); 
 | 
						|
 }; 
 | 
						|
 
 | 
						|
 function toSlide(n) { 
 | 
						|
  showSlide(slideIndex = n); 
 | 
						|
 }; 
 | 
						|
 
 | 
						|
 // This is your logic for the light box. It will decide which slide to show 
 | 
						|
 // and which dot is active. 
 | 
						|
 
 | 
						|
 function showSlide(n) { 
 | 
						|
  const slides = document.getElementsByClassName('slide'); 
 | 
						|
  let modalPreviews = document.getElementsByClassName('modal-preview'); 
 | 
						|
 
 | 
						|
  if (n > slides.length) { 
 | 
						|
    slideIndex = 1; 
 | 
						|
  }; 
 | 
						|
 
 | 
						|
  if (n < 1) { 
 | 
						|
    slideIndex = slides.length; 
 | 
						|
  }; 
 | 
						|
 
 | 
						|
  for (let i = 0; i < slides.length; i++) { 
 | 
						|
    slides[i].style.display = "none"; 
 | 
						|
  }; 
 | 
						|
 
 | 
						|
  for (let i = 0; i < modalPreviews.length; i++) { 
 | 
						|
    modalPreviews[i].className = modalPreviews[i].className.replace(' active', ''); 
 | 
						|
  }; 
 | 
						|
 
 | 
						|
  slides[slideIndex - 1].style.display = 'block'; 
 | 
						|
  modalPreviews[slideIndex - 1].className += ' active'; 
 | 
						|
 }; 
 | 
						|
` 
 | 
						|
 | 
						|
وهذا كل شيء! الآن ضع كل الكود معا. يجب أن يكون لديك الآن lightbox وظيفية.
 | 
						|
