The clever use of gradients in CSS

This time I will bring you the skillful use of gradients in CSS. What are the precautions for using gradients in CSS? The following is a practical case, let’s take a look.

Preface

This article mainly shares the relevant knowledge about linear-gradient and radial-gradient in CSS3, and brings you another way to use gradients. an angle. Interested friends, let’s take a look at the detailed introduction:

1. Linear gradient

You need to go here first Let’s take a look at the basic syntax and then look at the following examples.

    linear-gradient(90deg,red 20%,blue 50%,yellow 80%);

Obviously through this picture, you will roughly understand the role of setting these parameters. Although I didn't use any words to explain it. (So ​​when you can’t understand the definition, you must practice it.)

Next, we have to do something. We overlap the color separation points.

    width: 300px;
    height: 200px;
    background: linear-gradient(90deg,blue 100px,#fff 100px,#fff 200px,red 200px);

Yes, this is the effect produced by the above gradient code. Does it feel like it breaks your previous impression of gradients?

Next we use linear-gradient to achieve cooler effects, such as:

Do you feel that you have broken through your own understanding of gradients? know. Let me talk about the idea of ​​​​implementing this background: This is a regular pattern. We need to find its basic pattern. I believe you have found it.

Knowledge points we need to use:

• background supports the declaration of multiple linear-gradients, separated by commas;

• When you declare multiple linear-gradients, the one declared first is closer to the user. (Here we need to consider the issue of covering, usually transparent);

• I haven’t mastered the abbreviation of background yet, but it doesn’t work;

# A reasonable combination of
• ##background-repeat

  , background-size and background-position.

      width: 410px;
      height: 410px;
      background: linear-gradient(rgb(2,222,222) 10px, transparent 10px) repeat left top / 40px,
                  linear-gradient(90deg,rgb(2,222,222) 10px, transparent 10px) repeat left top / 40px;

Look, in the past, to achieve such an effect, we could only beg the artist to cut the image. Now in the wave of CSS3, we can be self-sufficient (^_^).

And through gradient we can animate the background color without consuming additional

HTML elements

to achieve the desired effect. Example:

    /*
     *  这里用scss写的，对新手不太友好，抱歉(-_-)
     */
    @mixin menuaction($color) {
        background: linear-gradient($color 100%, transparent 100%) no-repeat center bottom / 100% 10%;
        &:hover {
            background-size: 100% 100%;
            color: #fff;
        }
    }

2. Radial gradient

Basically, radial gradient is similar to linear gradient, except It spreads outward from the center point. So I won’t go into details here.

Without further ado, let’s draw concentric circles first:

    border-radius: 50%;
    background: radial-gradient(circle,rgb(22,222,111) 0,rgb(22,222,111) 50px,red 50px,red 100px, rgb(222,222,1) 100px, rgb(222,222,1) 150px,rgb(222,2,111) 150px);

What will it end with, haha, various discounts recently Coupon, then let’s use the knowledge of gradients to get a coupon:

The core code is as follows:

    width: 300px;
    height: 120px;
    background: radial-gradient(transparent 0, transparent 5px, rgb(247,245,201) 5px) no-repeat,
                radial-gradient(transparent 0, transparent 5px, rgb(247,245,201) 5px) no-repeat,
                radial-gradient(transparent 0, transparent 5px, rgb(247,245,201) 5px) no-repeat,
                radial-gradient(transparent 0, transparent 5px, rgb(247,245,201) 5px) no-repeat,
                radial-gradient(transparent 0, transparent 5px, rgb(247,245,201) 5px) no-repeat,
                radial-gradient(transparent 0, transparent 5px, rgb(247,245,201) 5px) no-repeat,
                radial-gradient(#fff 0, #fff 10px, rgb(247,245,201) 10px) no-repeat,
                radial-gradient(#fff 0, #fff 10px, rgb(247,245,201) 10px) no-repeat,
                linear-gradient(90deg,transparent 10px, rgb(247,245,201) 10px);
            background-size: 20px 20px,20px 20px,20px 20px,20px 20px,20px 20px,20px 20px,60px 60px,60px 60px,100% 100%;
            background-position: -10px 0,-10px 20px,-10px 40px,-10px 60px,-10px 80px,-10px 100px,60px -30px,60px 90px,left center;
