如何解决使用Unicode将FontAwesome绑定到:: before-显示crypdo-icon
我试图将FontAwesome包含在:: before-element中。 该网站的include起作用（我的网站上i元素中还有其他Icon），但unicode方式不起作用。
我试图像这样在fontAwesome中为上一个按钮添加一个图标：
.owl-carousel .owl-nav button.owl-next,.owl-carousel .owl-nav button.owl-prev,.owl-carousel button.owl-dot {
font-family: "fontAwesome";
}
.owl-carousel .owl-nav .owl-prev::before{
content: "\f053";
font-family: FontAwesome;
margin-right:10px;
}
但是它只是这样显示：
我测试了添加高度和宽度，使其成为块元素..似乎没有任何效果。我正在使用Contao CMS。
解决方法
当我通过开发工具将{{1}}插入按钮之前，然后对其进行检查时，它显示function generateThumbnail(outputPath,filename,thumbnailPath) {
return new Promise((resolve,reject) => {
gm(outputPath) // The name of your pdf
.setFormat("jpg")
.resize(200) // Resize to fixed 200px width,maintaining aspect ratio
.quality(75) // Quality from 0 to 100
.write(`${thumbnailPath}/${filename}.jpg`,function (error) {
// Callback function executed when finished
if (!error) {
resolve("Thumbnail generated")
} else {
reject(`error from gm,${error}`)
}
})
})
}
function libreConverter(readFile,outputPath) {
return new Promise((resolve,reject) => {
console.log('Conversion to PDF started');
libre.convert(readFile,"pdf",undefined,(err,done) => {
if (err) {
reject(`Libre error: ${err}`)
} else {
fs.writeFileSync(outputPath,done);
resolve("Converted to PDF");
}
});
})
}
function pdf2picConverter(outputPath,pdf2PicOptions) {
return new Promise((resolve,reject) => {
const pdf2pic = new PDF2Pic(pdf2PicOptions)
pdf2pic.convertBulk(outputPath,-1).then(() => { //resolve
resolve("PDF converted to png")
}).catch((err) => {
reject("error from PDF2Pic",err)
})
}
)
}
function converttoVideo(exportPath,videoOptions,videoPath) {
return new Promise((resolve,reject) => {
fs.readdir(exportPath,data) => {
if (!err && !_.isEmpty(data)) {
const imagePaths = data.map(item => `${exportPath}/${item}`)
videoshow(imagePaths,videoOptions)
.save(`${videoPath}/${filename}.mp4`)
.on('start',function (command) {
console.log('videoshow process started:',command)
})
.on('error',function (err,stdout,stderr) {
reject('videoshow Error:',err)
})
.on('end',() => {
resolve("Video saved")
})
} else {
reject("error from readdir",err)
}
})
}
)
}
function p2vConverter(filepath,pdf2PicOptions,videoPath,thumbnail,thumbnailPath) {
return new Promise(async (resolve,reject) => {
try {
const outputPath = path.join(__dirname,"../uploads/",`Folder_${filename}/`,`${filename}.pdf`)
const exportPath = path.join(__dirname,"outputs")
const dir = path.join(__dirname,`Folder_${filename}`)
fs.mkdir(exportPath,{ recursive: true },(err) => {
if (err) throw err;
});
const readFile = fs.readFileSync(filepath);
await libreConverter(readFile,outputPath).then(libreMessage => console.log(libreMessage)).catch(err => console.log(err))
if (thumbnail) {
await generateThumbnail(outputPath,thumbnailPath).then(thumbnailMessage => console.log(thumbnailMessage)).catch(err => console.log(err))
}
pdf2PicOptions.savedir = exportPath
pdf2PicOptions.savename = filename
await pdf2picConverter(outputPath,pdf2PicOptions).then(p2pMessage => console.log(p2pMessage)).catch(err => console.log(err))
await converttoVideo(exportPath,videoPath).then(ctvMessage => {
return ctvMessage
}).catch(err => console.log(err))
fs.rmdir(dir,(err) => {
if (err) {
reject("error from rmdir",err)
}
console.log(`${dir} is deleted!`);
});
resolve(`${videoPath}/${filename}.mp4`)
} catch {
reject()
}
})
}
const videoOptions = {
fps: 25,loop: 5,// seconds
transition: true,transitionDuration: 1,// seconds
videoBitrate: 1024,videoCodec: 'libx264',size: '640x?',format: 'mp4',pixelFormat: 'yuv420p'
}
const pdf2PicOptions = {
density: 100,// output pixels per inch
format: "png",// output file format
size: "600x600" // output size in pixels
}
const videoPath = path.join(__dirname,"../uploads/")
const thumbnail = true;
const thumbnailPath = path.join(__dirname,"../uploads/")
await p2vConverter(file.path,file.filename,thumbnailPath).then(output => console.log(`video saved at: ${output}`))
元素的字体系列为<i class="fas fa-chevron-left"></i>-您使用了i代替按钮"Font Awesome 5 Free"元素。
