I have a site hosted with github pages built using Jekyll.
One of the plugins I have installed in html-proofer. This was working fine until I switched my images to use picturefill.
By using Picturefill, I am using the currently invalid <picture> tag. This causes html-proofer to fail when I deploy.
So my question - how can I tell html-proofer to ignore all <picture> tags?
My setup:
gemfile:
source 'https://rubygems.org'
gem 'github-pages'
gem 'html-proofer'
.travis.yml:
language: ruby
rvm:
- 2.1
script: script/cibuild
sudo: false
env:
global:
- NOKOGIRI_USE_SYSTEM_LIBRARIES=true # speeds up installation of html-proofer
script/cibuild:
set -e # halt script on error
bundle exec jekyll build
bundle exec htmlproof ./_site
UPDATE:
I've found that it's not actually the <picture> element that is causing the problem, but rather the <img> tag inside it. This is because the <img> does not have a src but rather a srcset:
<picture>
<!--[if IE 9]><video style="display: none;"><![endif]-->
<source srcset="examples/images/extralarge.jpg" media="(min-width: 1000px)">
<source srcset="examples/images/large.jpg" media="(min-width: 800px)">
<!--[if IE 9]></video><![endif]-->
<img srcset="examples/images/medium.jpg" alt="A giant stone face at The Bayon temple in Angkor Thom, Cambodia">
</picture>
Adding data-proofer-ignore to the img tag solves the problem, but I'd rather not have to do this on every instance.
I posted an issue on the html-proofer repo, where I was told that the srcset error is a bug.
Unfortunately, the maintainer indicated that there is no way to ignore specific tags when running the plugin:
