data-uri

问题 I am using the js plugin that adds inside itself SVG images. I have added CSP policy to my website, but I can't configure it to allow plugin's code. Its code looks like: label=$("<object style='height:10px; width:10px;' type='image/svg+xml' data='data:image/svg+xml;charset=UTF-8," + "<svg xmlns=\"http://www.w3.org/2000/svg\">" + "<rect x=\"0\" y=\"0\" some parameters/>"+ "<text>SomeText</text></svg>'></object>"); el.html(label) I am looking for a configuration that allows SVG image that is

问题 I am using requests to get the image from remote URL. Since the images will always be 16x16, I want to convert them to base64 , so that I can embed them later to use in HTML img tag. import requests import base64 response = requests.get(url).content print(response) b = base64.b64encode(response) src = "data:image/png;base64," + b The output for response is: response = b'GIF89a\x80\x00\x80\x00\xc4\x1f\x00\xff\xff\xff\x00\x00\x00\xff\x00\x00\xff\x88\x88"""\xffff\... The HTML part is: <img src="

问题 I have some inline SVG with class names for styling via CSS selectors. I would like to bring the SVG into my CSS as a background-image data URI, but does this mean I can't use the CSS selectors anymore? I've read the existing StackOverflow responses, and the takeaway seems to be "You can't apply CSS because it's an image or resource from potentially another site". How do I change the colour of an SVG image in a CSS content property? Modify SVG fill color when being served as Background-Image

问题 Problem background: I am using katex to render some math on a page. I then want to create a PDF version of part of that page, so I create a HTML document that containing the part to be exported that inlines all CSS and pass it to the renderer. The renderer cannot access the node resources, that's why everything is inlined. It works perfectly, except for the fonts. I tried both url-loader and bas64-inline-loader, but the generated fonts are not inlined. I inspected the generated CSS in the

问题 I’m trying to implement mixin customizing underline of text, like polyfill for CSS3 text-decoration properties: line, style, color, which are not supported yet by browsers. My idea is to perform painting proper line in canvas, then convert it to data-uri and use it as background for target element. Problem is when compiling LESS with node.js, there is no canvas in environment. Technically I could use node-canvas to perform this task, but I don’t want to make any dependencies for node just to

问题 'Edge 75' will be (is?) the first Chromium Based Edge browser. How can I check if this browser is Edge on Chrome ? (What I really want to know is if the browser fully supports data-uri's - https://caniuse.com/#feat=datauri - so feature detection would even be better. If you know a way to do that, I can change the question) 回答1: You could use the window.navigator userAgent to check whether the browser is Microsoft Chromium Edge or Chrome. Code as below: <script> var browser = (function (agent)
