HTML use_html/css_WEB-ITnose

Please tell me how to set a color in pure HTML language. For example, I want to set a blue strip chart at the top.
And how to draw a waveform chart using HTML? I want to use HTML to make an embedded web Display voltage like an oscilloscope

No unless you use css HTML only controls the structure and css controls the style

Waveform chart It is recommended that you use a plug-in called flotr which is relatively simple

Pure HTML cannot be implemented. HTML is just a structure and must be combined with CSS to achieve style.

Please search for graphics plug-ins and JS tools...

It is recommended that you use HTML5 CSS3, but it may not support lower version browsers.
