Reply to the discussion (solution)
There are many ways , canvas, svg drawing, you can also use tables and divs to remove part of the border (but this kind of CSS requires a lot of writing).
I came out
Specifically, how to use tables and divs, how to remove borders with css
Do you want to use it for display or do you want to make a maze on the web page? , allows people to leave?
For the former, just paste the picture.
For the latter, use canvas JS.
<!doctype html><html lang="en"><head> <meta charset="UTF-8"> <title> 页面名称 </title><style type="text/css">#map { width: 124px; height: 124px;}#map div { width: 30px; height: 30px; float: left; border: 1px solid transparent; margin: 0px -1px -1px 0px;}#map .l {border-left: 1px solid #000;}#map .r {border-right: 1px solid #000;}#map .t {border-top: 1px solid #000;}#map .b {border-bottom: 1px solid #000;}</style></head><body><div id="map"> <div class="l t"></div> <div class="l"></div> <div class="t"></div> <div class="t r"></div> <div class="l"></div> <div class="t"></div> <div class="t l"></div> <div class="r"></div> <div class="l"></div> <div class="t"></div> <div class=""></div> <div class="l t r"></div> <div class="l t b"></div> <div class="b"></div> <div class="t b"></div> <div class="r b"></div></div> </body></html> Jsoup
Document doc1 = Jsoup.connect("http://www.paperyy.com/").get();
The following is the code to generate a perfect maze. Just pick two places on the edge as the entrance and exit respectively
