Css text from image

CSS: Placing text over an inline image

CSS is a very powerful tool that works best when kept as simple as possible. Unfortunately there are a lot of WYSIWYG applications and other HTML editors that produce CSS that is anything but simple.

A common request is to be able to display HTML text over an image that’s already embedded on the page. There are a number of valid solutions using either tables or CSS.

Using a TABLE to overlay text on an image

The HTML solution has been possible since Netscape 3 and is fairly simple to implement, but not so flexible as more recent options.

(text to appear over the image goes here)

The HTML approach is to set up a TABLE with a background image. Then a single TD is used to display the text. The width and height of the TABLE are set to match that of the background image. This is a valid approach according to HTML standards, but not so good if you look at the resulting code. Why should you have to use a TABLE to handle this kind of layout? Perhaps CSS has a cleaner solution.

Many years ago this was a novel approach, but these days it’s very much discouraged.

Using CSS to overlay text on an image

Indeed there is a simpler, more flexible solution. Instead of a TABLE we use a DIV and CSS positional attributes to place futher text and images with relation to that DIV.

As you can see, we are able to place any number of sub-elements within the surrounding div. In this case a div containing paragraphs with text (bottom left), and a paragraph by itself (top right).

The CSS approach is to use one DIV to define the area where the background image appears. This DIV has it’s position attribute set to relative in order that the items it contains can be properly placed.

This is done by setting the position attribute of contained items to absolute and placing them by setting one or more of the positional attributes: top, right, bottom and left.

This block has been positioned at the top, right

The position attribute may seem complicated at first, but it’s the key to implementing complicated layouts without excessive amounts of code. Remember that you need to have a container element with position: relative in order to place inner elements using position: absolute.

Without a container element all positioning will be in relation to the viewport (the corner of the screen). This in combination with position: fixed can create elements that stay in one corner of the screen and don’t move when the page scrolls, but only in browsers other than Explorer. On this site you might see a [top] link doing just that if you’re using a compatible browser.

Separating styles from content

Normally you will want to have your CSS in a separate file or at least it’s own style block rather than inline with the HTML. This can be easily achieved by assigning CSS classes to the various container elements:

The result is idential to the previous example, but now much easier to maintain as the HTML and CSS can be edited independently.

Showing text over an image on hover

Sometimes you only want text to appear when the mouse is over the image or the image has focus. One nice way of achieving this is to wrap the image in a link and use the title attribute to store the caption.

In the example below you can see this in action. We’ve set the outer link to position: relative and used its title attribute attr(title) to create some generated content and place it over the image.

The generated content is initially hidden opacity: 0 and then exposed using the hover/focus state and a CSS animation fader.

The slow fade may still not work in some browsers as they don’t support transition effects on generated content. It does fade in in Firefox 23.0.

The attr method in CSS is extremely useful as it allows you to embed data into HTML elements for use in generated content. In this case we’re using the title attribute, but you can also create your own custom attributes. In that case the custom is to name them data-* (e.g. data-hovertext).

Source code for this example:

You could also place HTML text over the images as in the earlier examples and have it show/hide the same way, but that’s not nearly as cool.

Converting Image to HTML/CSS

Converting Image to HTML/CSS

One of the most common questions is how long does it take to convert images into HTML codes. This question has a broad answer and we will try to give a detailed answer to it.

The conversion of the image to HTML / CSS code occurs when the project reaches the phase where the developers must implement the design. But do you know how to convert images to code if you don’t know what programming is and how to work with codes? Some tools will speed up the process of converting these designs into real websites.

What is HTML?

HTML (Hypertext Markup Language) is a programming language used to define parts of web pages or mobile applications for the web browsers that visit them. HTML is the simplest block in web development, which is why it is so important to learn.

HTML tells browsers which port is the header or footer of a web page, where any paragraph goes, where graphics, images, and videos, etc. are placed.

  • The browser takes HTML content and converts it to what people see on their device screen.
  • HTML is the standard language that all web browsers understand.
  • HTML is also the generally accepted standard for search engines like Google, Yahoo, or Bing to build websites based on relevant search queries.

Hand Coding or Image to Code Converters

Hand coding gives you maximum flexibility and insight into the inner workings of your site. It is important to know your site inside and out. This makes repairs easier because you usually have a much better understanding of what’s going on than you would otherwise. However, this requires a deep understanding of the code. If you are not a programmer, writing code by hand is simply impractical.

Let’s take a look at three simple cases of converting images to HTML and CSS codes.

  • Converting website template from PNG to HTML code — You may have designed your website layout and saved it in PNG format, but now you will need to convert them to HTML web pages. In this case, you need to know a thing or two about HTML and CSS, even more.
  • Converting the code image file to HTML text. You can get an image file that stores HTML text, and now you need to extract HTML text from PNG using OCR technology, and then copy and paste those texts into your HTML file.
  • Displaying an image in an HTML file. If you have an HTML file and need to display an image on a web page, you need to first upload the PNG image to your website server, and then add the HTML code to display the image appropriately.

Convert Code PNG Image to HTML text

To extract the code from the PNG image and then add it to the HTML file, OCR is required. OCR stands for Optical Character Recognition, it helps to recognize text from image-based files such as scanned files or text images. To convert PNG to HTML for free, we choose 3 free online tools.

#1 online-convert

There are dozens of online images to HTML converters, but Online-Convert is the only one that performs OCR on a PNG image and then exports it as an editable HTML format. It is a powerful online converter for working with archives, audio files, devices, documents, e-books, images, videos, etc.

  • Go to https://document.online-convert.com/convert-to-html;
  • Click “Choose Files” to upload the PNG image;
  • Change the settings according to your needs — (Optional);
  • Click “Start conversion” to turn PNG to HTML;
  • Once the conversion is done, click “Download” to export PNG as HTML format.

#2 convertio.co

Although the conversion does not support exporting PNG as HTML text directly, it is capable of performing OCR to save PNG in editable text, word, or other formats, then you just need to paste the recognized text into the HTML file.

Convertio OCR can save PDF and various images in 11 editable formats, it is also able to recognize multiple languages and process fast on the OCR job.

  • Go to Convertio OCR. https://convertio.co/ocr/;
  • Click “From Computer” to upload the PNG image;
  • Choose file language, output, and page range;
  • Click “Recognize” to turn PNG image to text;
  • Copy/paste the text to your HTML image and save it.

# 3 online2pdf

  • online2pdf is another platform that allows users to convert PDFs and images to various formats, it is capable of performing OCR on scanned PDFs or images and exporting them to editable formats such as text, Word, Excel, etc. This allows users to customize the file to a limited extent.
  • Go to the online2pdf website;
  • Click Select Files to upload PNG files;
  • Select output as text and select the language of the file;
  • Click «Convert» to export the PNG image as text;
  • Copy and paste the text into an HTML file, save the file.

Display Image in HTML file

As we know, an image can’t be directly added into an HTML file, we need to turn the image into code. To display an image in an HTML file, you need to upload a PNG image to the server and get the URL. Many platforms allow users to upload images online.

  • Step 1. Go to https://imgbb.com/;
  • Step 2. Click “Start Uploading” > “Upload” your PNG image to the website server;
  • Step 3. In the Insert Codes section, select Full HTML Link and then copy the codes as follows:
