On my Ubuntu box I have installed htlm2ps in order to convert a simple html file to a GIF. My html file looks like this:
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset="utf-8">
</head>
<body style="width: 120px; height: 90px" >
<div>
<div>Gas Prices</div>
<div>Todays local Prices</div>
<div>Low Price 1.29</div>
<div>High Price 1.44</div>
</div>
</body>
</html>
and I run convert like this:
convert -size 120x90 gas.html gas.gif
However, the generated image is always of size 612x712. Same thing when converting to PNG or JPG.
Any ideas what I'm doing wrong?
The -size option in Imagemagick is ignored as the page size is determined by html2ps converting the HTML into PostScript. I believe you'll need to set the size of the page with CSS within the document. See #paper option under html2ps's documentation.
/*
Check your version of html2ps, as #paper my have been replace with #page selector
*/
#paper {
width: 120px;
height: 90px;
/* Note: Units may need to be converted to `em' or `pt' */
}

I'm maintain and old code that load css like below:
<style type="text/css">
<%= Rails.application.assets[filename].to_s.html_safe %>
</style>
It'd show in browser html like
<style type="text/css">
#charset "UTF-8";
/*
line 2, xxxx_path
*/
#div1 {
...
}
#div2 {
...
}
</style>
It works fine in local but when on production it shows in browser HTML like:
<style type="text/css">
#div1 {...}#div2{...}
</style>
and when I edit it as HTML it actually shows:
<style type="text/css">
#div1{...}#div2{...}
</style>
So it cause css selector is wrong because it seems #div1 instead #div1.
I want to know:
How to fix it?
why this happened?
why we use request to load CSS like stylesheet_link_tag will not have this problem?
BTW I tried rake asset:compile ENV=produciton still local is working fine.
I'm working with Sendgrid's template system and need to manually inline some css for content that will be included in the Sendgrid smtpapi call.
Premailer doesn't seem to be actually inlining the css styles. I can inspect the result of calling Premailer.new but the processed_doc and doc both do not have the styles inlined.
Different methods I've tried:
Including the css file directly:
header = <<-HTML
<div class="preview-content">
#{data["content"]}
</div>
HTML
p header
=> "<div class=\"preview-content\">\n<p>Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. </p>\n</div>\n"
premailer = Premailer.new(header, with_html_string: true, adapter: :nokogiri,css: [Rails.root.join('app', 'assets', 'stylesheets', 'email_base.css').to_s], input_encoding: "UTF-8", verbose: true)
p premailer.processed_doc.to_html
=> "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n<html><body>\n<div class=\"preview-content\">\n<p>Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean.</p>\n</div>\n</body></html>\n"
premailer.doc.to_html returns the same thing with no inlined css.
I checked that the css file is accessible and that the styles apply to .preview-content p.
Adding a header to the document
header = <<-HTML
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8"> <!-- utf-8 works for most cases -->
<meta name="viewport" content="width=device-width"> <!-- Forcing initial-scale shouldn't be necessary -->
<meta http-equiv="X-UA-Compatible" content="IE=edge"> <!-- Use the latest (edge) version of IE rendering engine -->
<title></title> <!-- The title tag shows in email notifications, like Android 4.4. -->
<link rel="stylesheet" href="/asset/email_base.css" media="all">
</head>
<body width="100%" height="100%" bgcolor="#ffffff" style="margin: 0; padding: 0 20px;">
<div class="preview-content">
#{data["content"]}
</div>
</body>
</html>
HTML
p header
=> '<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">\n <html xmlns=\"http://www.w3.org/1999/xhtml\">\n <head>\n <meta charset=\"utf-8\"> <!-- utf-8 works for most cases -->\n <meta name=\"viewport\" content=\"width=device-width\"> <!-- Forcing initial-scale shouldn't be necessary -->\n <meta http-equiv=\"X-UA-Compatible\" content=\"IE=edge\"> <!-- Use the latest (edge) version of IE rendering engine -->\n <title></title> <!-- The title tag shows in email notifications, like Android 4.4. -->\n <link rel=\"stylesheet\" href=\"/asset/email_base.css\" media=\"all\">\n </head>\n <body width=\"100%\" height=\"100%\" bgcolor=\"#ffffff\" style=\"margin: 0; padding: 0 20px;\">\n <div class=\"preview-content\">\n<p>Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean.</p></div>\n </body>\n </html>\n'
The desired css to be inline:
.the-excerpt,
.the-excerpt p,
.preview-content p
// +responsive-text(18px, 30px)
line-height: 1.8 !important
font-size: 18px
Is there something I'm missing to inline css manually? Both ways don't seem to yield any different results.
I'm trying out Premailer right now, and having some problems of my own.. but the way that i see Premailer actually processing the content and getting something different back (it removes the classes with the proper configuration setting, at least) is using this method:
premailer = Premailer.new(html, { :with_html_string=>true, :verbose=>true, :remove_classes=>true })
return premailer.to_inline_css
The html looks like this:
<html>
<head>
<style type="text/css">
h1:before
{
content: '\292d';
}
</style>
</head>
<body>
<h1>Sample Text</h1>
</body>
</html>
So, I've already converted the '⤭' character to ASCII which shows fine in my desktop's browser; however, on iPhone, it's blank!
The problem could be with content: '\292d'; even though they say content is supported with safari 1.0 and up it still does not work properly.
i used it for displaying images and it used to show up in inspect element but not in browser window, the entity '\292d' is infact supported
instead Try putting it directly inside the tag, or use javascipt if you want it to be dynamically inserted
Help. Am learning HTML5/CSS. Things are going spiffy until I cannot debug my HTML/CSS markup.
Am using WeBuilder which auto-completes and has links to standard tools like Tidy and others.
Here is what I’ve tried
used an internal CSS link in my HTML: it works;
put the styles.css in same and in a css folder- BUMMER
have relocated both files to another HDD- BUMMER
both files validate with my available tools
I am sure the problem is in the HTML file and have fiddled with every modification I can find suggestions about. I have rewritten the HTML again using WeBuilder’s auto complete but have not done it in Notepad. I understand the basics of HTML and CSS plus am very familiar with files and folders so have directed the href correctly (even so have tried several ideas from W3C.
NOTE: I see in the "publish" here, it picks up the Arial font where mine has times. If Arial is not your default, I'm at a loss because the color doesn't show. Neither shows the color. If I can be of further help please advise. I really thank you for any help.
Here is my HTML markup:
<!DOCTYPE html5>
<html>
<head>
<title>A Simple Page</title>
<meta http-equiv="content-type" content="text/htm; charset=utf-8">
<meta name="description" content="">
<meta name="keywords" content="">
<style type="text/css">
<link rel="stylesheet" href="styles.css" />
</style>
</head>
<body>
<h1>First Title</h1>
<p>A paragraph of interesting content</p>
<h2>Second Title</h2>
<p>A paragraph of interesting content</p>
<h2>Third Title</h2>
<p>A paragraph of interesting content</p>
</body>
</html>
Here is the CSS:
h1, h2 {
color: #3366CC;
font-family: "Arial", sans-serif;
}
This makes no sense:
<style type="text/css">
<link rel="stylesheet" href="styles.css" />
</style>
It should simply be:
<link rel="stylesheet" href="styles.css" type="text/css" />
The <style> tags are only used for inline CSS in a page. So if you wanted to you could do this:
<style type="text/css">
h1, h2 {
color: #3366CC;
font-family: "Arial", sans-serif;
}
</style>
But it is really better to keep CSS in a separate file.
Also, there is a minor issue with your DOCTYPE at the top of your HTML file. An HTML5 DOCTYPE is simply:
<!DOCTYPE html>
And not:
<!DOCTYPE html5>
The purpose of HTML5 is to—among other things—simplify document formatting & readability. So there is no such thing as <!DOCTYPE html5> it is simply <!DOCTYPE html>.
Currently I am using the JavaFx Webview to load a HTML page. But there is a problem when it loads the HTML page. It doesn't read the letter-spacing or -webkit-letter-spacing attribute in CSS. It's fine with the Chrome browser. How can I make it work in JavaFx?
<!doctype html>
<html>
<head>
<meta charset="utf-8"/>
<title>test</title>
<style>
.text {
letter-spacing: 20px;
}
</style>
</head>
<body>
<div class="text">
abcdefg
</div>
</body>
</html>
Looks like this property is not supported in JavaFX/JDK 7, but works for me in JavaFX/JDK 8. As far as I know, some of the WebViews rendering bugs fixed in JDK 8 won't be backported to JDK 7 and this one seems like being one of such bugs.
