These look like CSS custom properties (CSS variables) used by a design system or library to control an animation. Explanation:

• -sd-animation: sd-fadeIn;
  • Purpose: selects a named animation (here, “sd-fadeIn”) that the component or library will apply.
  • Usage: the library’s stylesheet likely maps that name to keyframes or animation presets.
• –sd-duration: 250ms;
  • Purpose: sets the animation duration to 250 milliseconds.
  • CSS type: time value; can be used in an animation shorthand or transition (e.g., animation-duration: var(–sd-duration);).
• –sd-easing: ease-in;
  • Purpose: sets the animation timing function to ease-in.
  • CSS type: timing-function; used like animation-timing-function: var(–sd-easing);.

Example usage in CSS (assuming the library reads these variables or you implement them):

.component {/* library-specific trigger /  -sd-animation: sd-fadeIn;  –sd-duration: 250ms;  –sd-easing: ease-in;
  / hookup if you implement the behavior yourself /  animation-name: var(–sd-animation); / requires the custom property to contain a keyframe name */  animation-duration: var(–sd-duration);  animation-timing-function: var(–sd-easing);  animation-fill-mode: both;}

If the library uses named presets instead of raw keyframe names, set -sd-animation to the preset name and the library will apply the corresponding animation, duration, and easing automatically. To change behavior, adjust the variables or override them in a more specific selector.

Quickly Convert PDF to Text: Fast Methods for Any Device

Converting a PDF to editable text can save time and make document editing, searching, and repurposing much easier. Below are fast, reliable methods you can use on Windows, macOS, Linux, Android, and iPhone—plus tips for accuracy and batch processing.

1. Use built-in tools (fastest for simple PDFs)

• Windows: Open the PDF in Microsoft Word (2013 or later) — Word will convert many PDFs to editable text automatically; then save as .docx or copy the text.
• macOS: Open the PDF in Preview, select text and copy. For longer docs, open in Pages or use Automator’s “Extract PDF Text” action.
• Linux: Use pdftotext (poppler-utils) in terminal:
  pdftotext input.pdf output.txt

  This is fast and preserves text flow for most PDFs.

2. Use free online converters (best for quick, small files)

• Upload the PDF to a reputable online converter, download the .txt or .docx output. Good for one-off conversions but avoid uploading sensitive documents.

3. Use OCR for scanned PDFs

• If the PDF is an image scan, use OCR (Optical Character Recognition):
  • Desktop: Adobe Acrobat Pro (Recognize Text), ABBYY FineReader.
  • Free: Tesseract OCR (command line) — example:
    tesseract input.pdf output -l eng pdf

  • Mobile: Google Drive (upload image PDF → Open with Google Docs) or dedicated OCR apps.

4. Batch conversion for many files

• Command-line tools are ideal:
  • pdftotext for native PDFs:
    for f in.pdf; do pdftotext “\(f" "\){f%.pdf}.txt”; done

  • Use OCR in batch with Tesseract or scripts that call commercial OCR engines.

5. Maintain formatting and accuracy

• PDFs with complex layouts (columns, tables) may need post-conversion cleanup.
• For tables, convert to .docx or .xlsx and check cell alignment.
• Proofread OCR output; use spell-check and search/replace to fix common OCR errors.

Quick workflow recommendations

• For editable PDFs: use pdftotext or Word/Pages.
• For scanned PDFs: use OCR (Tesseract for free, ABBYY/Adobe for higher accuracy).
• For many files: script pdftotext or OCR tools in batch.
• For sensitive files: convert locally with desktop tools rather than online services.

Tools at a glance

• Lightweight/free: pdftotext, Tesseract, Google Drive (Docs).
• Desktop paid/high-accuracy: Adobe Acrobat Pro, ABBYY FineReader.
• Mobile: Microsoft Lens, Adobe Scan, OCR apps.

Converting PDFs to text is straightforward once you pick the right tool for the file type (native vs scanned) and volume. For most users, pdftotext or Word/Pages covers quick needs; use OCR when necessary to extract text from images.

Those are CSS custom properties (CSS variables) likely used by a library or component for controlling an animation. Breakdown:

• –sd-animation: sd-fadeIn;
  • Name of the animation to apply (likely mapped to a keyframes rule called sd-fadeIn).
• –sd-duration: 0ms;
  • Duration of the animation; here set to 0ms so the animation will have no visible duration (instant).
• –sd-easing: ease-in;
  • Timing function controlling the animation’s acceleration curve; “ease-in” starts slow and speeds up.

How they’re used (example):

.element {animation-name: var(–sd-animation);  animation-duration: var(–sd-duration);  animation-timing-function: var(–sd-easing);}@keyframes sd-fadeIn {  from { opacity: 0; transform: translateY(8px); }  to   { opacity: 1; transform: translateY(0); }}

Notes:

• p]:inline” data-streamdown=“list-item”>These variables allow easy theming per-component or runtime overrides.

Easy 7-Zip Tricks: Compress, Encrypt, and Share in Minutes

Why 7-Zip?

7-Zip is a free, open-source file archiver that offers high compression ratios, strong AES-256 encryption, and a simple interface. It works on Windows (with unofficial ports for macOS/Linux) and supports formats like 7z, ZIP, TAR, and more. These tricks will help you save space, protect sensitive files, and share archives quickly.

1) Quick compression for everyday files

1. Select the files or folder.
2. Right-click and choose 7-Zip → Add to archive….
3. Set Archive format to 7z (better compression) or zip (more compatibility).
4. For balanced speed and size, choose Compression level: Normal and Compression method: LZMA2.
5. Click OK.

Tip: Use “Add to archive” with the default settings for a fast, small archive when you don’t need maximum compression.

2) Fast batches with “Add to .7z”

• Right-click any file or folder and pick 7-Zip → Add to “filename.7z” to instantly create an archive using default settings.
• Use this for many small tasks when you don’t need to tweak options.

3) Split large archives for sharing

1. In Add to archive…, set Split to volumes, bytes (e.g., 100M for 100 MB chunks).
2. Click OK. 7-Zip creates multiple .7z.001, .7z.002 files that recombine when extracted.

Useful when email or cloud services limit single-file sizes.

4) Strong encryption with AES-256

1. In Add to archive…, enter a password under Encryption.
2. Choose Encryption method: AES-256.
3. For extra protection, set Archive format: 7z (ZIP AES support is limited).
4. Click OK.

Warning: If you lose the password, encrypted archives cannot be recovered.

5) Create self-extracting archives (SFX)

1. Choose Archive format: 7z.
2. Check Create SFX archive.
3. Click OK. The output is an .exe that extracts without needing 7-Zip installed — handy for recipients who aren’t tech-savvy.

Note: Some email services block .exe attachments; use cloud links instead.

6) Command-line shortcuts for power users

• Compress a folder:

7z a archive.7z C:\path\to\folder

• Encrypt and compress:

7z a -t7z -mhe=on -pYourPassword archive.7z C:\path\to\files

• Split archive into 100MB volumes:

7z a -v100m archive.7z C:\path\to\files

7) Verify archive integrity

• After creating, right-click the archive → 7-Zip → Test archive. 7-Zip reports errors if the file is corrupted.

8) Share safely and efficiently

• For large files: split into volumes or upload to cloud storage and share a link.
• For encrypted files: send the password via a different channel (e.g., SMS or phone call).
• Consider using ZIP format if recipients use macOS without 7-Zip.

Quick workflow example

1. Select folder → Right-click → Add to “backup.7z”.
2. If >100 MB, recreate with Split to volumes, bytes: 100M.
3. Add password with AES-256 and Create SFX if needed.
4. Upload to cloud and send link; share password separately.

Closing tips

• Keep 7-Zip updated for best performance and security.
• Use AES-256 for sensitive data.
