How to make a buttons with colors of the rainbow in my cycle in html?












0














My project is made on jango framework.



{% for tag in tags %}
<div class="btngroup" role="group" aria-label="tags">
<h3><a href="{{ tag.get_absolute_url }}" class="btn btn-primary">{{tag.title}}</a></h3>
</div>
{% endfor %}


I will explain a little. In this cycle, I get link tags from the database, which I want to wrap in buttons of different colors of the rainbow. But how to do that ?

          You can use HSL to easily create a color based on the item index and the total items in your array. H is for Hue, which is from 0 to 360. 0 is red, 120 is green, 240 is blue. You can simply calculate the percentage of 360 based on the index of the item in the loop.



          So first, you need to create a filter because you won't be able to do calculations directly in a Django template. Create a folder named templatetags with two files inside: an empty __init__.py and rainbow.py with the following content:



          from django import template
          register = template.Library()

          @register.filter()
          def rainbow(i, array):
          return 360 * i / len(array)


          Then, modify your code like this, so the background is changed with CSS, defining HSL colors. Make sure to include the filter:



          {% load rainbow %}
          {% for tag in tags %}
          <div class="btngroup" role="group" aria-label="tags">
          <h3>
          <a href="{{ tag.get_absolute_url }}" style="background:hsl({{ forloop.counter|rainbow:tags }},80%,50%)" class="btn btn-primary">{{tag.title}}</a>
          </h3>
          </div>
          {% endfor %}


          forloop.counter in Django will get the index of the current item in the loop. 80% is for S(saturation) and 50% for L(lightness). You might want to fine-tune this to match your design.

          You can use background-image: linear-gradient on your .btngroup class. Set the height and width to what you prefer:






          .btngroup {
          display: flex;
          justify-content: center;
          align-items: center;
          width: 100px;
          height: 50px;
          background-image: linear-gradient(to right, red,orange,yellow,green,blue,indigo,violet);
          border-radius:4px;
          color: white;
          }

          <div class="btngroup">Button<div>

                You can use background-image: linear-gradient on your .btngroup class. Set the height and width to what you prefer:






                .btngroup {
                display: flex;
                justify-content: center;
                align-items: center;
                width: 100px;
                height: 50px;
                background-image: linear-gradient(to right, red,orange,yellow,green,blue,indigo,violet);
                border-radius:4px;
                color: white;
                }

                <div class="btngroup">Button<div>








                .btngroup {
                display: flex;
                justify-content: center;
                align-items: center;
                width: 100px;
                height: 50px;
                background-image: linear-gradient(to right, red,orange,yellow,green,blue,indigo,violet);
                border-radius:4px;
                color: white;
                }

                <div class="btngroup">Button<div>





                .btngroup {
                display: flex;
                justify-content: center;
                align-items: center;
                width: 100px;
                height: 50px;
                background-image: linear-gradient(to right, red,orange,yellow,green,blue,indigo,violet);
                border-radius:4px;
                color: white;
                }

                <div class="btngroup">Button<div>
