如何減少梯度誤差？

Question

我只是想驗證一個大的CSS文件，並最終有89個錯誤！爲了節省時間，我嘗試在color zilla上使用跨瀏覽器漸變生成工具。這些生成的梯度最終導致我的錯誤的約90％：

background: rgb(56,115,160); /* Old browsers */ 
background: -moz-linear-gradient(top, rgba(56,115,160,1) 0%, rgba(55,107,147,1) 100%); /* FF3.6+ */ 
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(56,115,160,1)), color-stop(100%,rgba(55,107,147,1))); /* Chrome,Safari4+ */ 
background: -webkit-linear-gradient(top, rgba(56,115,160,1) 0%,rgba(55,107,147,1) 100%); /* Chrome10+,Safari5.1+ */ 
background: -o-linear-gradient(top, rgba(56,115,160,1) 0%,rgba(55,107,147,1) 100%); /* Opera 11.10+ */ 
background: -ms-linear-gradient(top, rgba(56,115,160,1) 0%,rgba(55,107,147,1) 100%); /* IE10+ */ 
background: linear-gradient(top, rgba(56,115,160,1) 0%,rgba(55,107,147,1) 100%); /* W3C */ 
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#3873a0', endColorstr='#376b93',GradientType=0); /* IE6-9 */ 

我的錯誤讀：

391  #nav Value Error : background Too many values or values are not recognized : -moz-linear-gradient(top,rgba(21,60,91,1) 0%,rgba(43,63,81,1) 100%) 

392  #nav Value Error : background Too many values or values are not recognized : -webkit-gradient(linear,left top,left bottom,color-stop(0%,rgba(21,60,91,1)),color-stop(100%,rgba(43,63,81,1))) 

393  #nav Value Error : background Too many values or values are not recognized : -webkit-linear-gradient(top,rgba(21,60,91,1) 0%,rgba(43,63,81,1) 100%) 

394  #nav Value Error : background Too many values or values are not recognized : -o-linear-gradient(top,rgba(21,60,91,1) 0%,rgba(43,63,81,1) 100%) 

395  #nav Value Error : background Too many values or values are not recognized : -ms-linear-gradient(top,rgba(21,60,91,1) 0%,rgba(43,63,81,1) 100%) 

396  #nav Value Error : background Too many values or values are not recognized : linear-gradient(top,rgba(21,60,91,1) 0%,rgba(43,63,81,1) 100%) 

397  #nav attempt to find a semi-colon before the property name. add it 

397  #nav Property progid doesn't exist : DXImageTransform 

397  #nav Parse Error DXImageTransform.Microsoft.gradient(startColorstr='#153c5b', endColorstr='#2b3f51',GradientType=0); 

梯度在所有瀏覽器很好看。我應該關心這些錯誤嗎？ 如果是這樣，我最好的選擇是什麼？

Answer 1

您不應該擔心這些錯誤。因爲它們是供應商特定的，所以它們不會進行驗證。我建議下次驗證時不要檢查供應商特定的前綴。

Answer 2

不要期望你的CSS完全通過W3C驗證器驗證。請參閱http://na.isobar.com/standards/#_css_validation
